range, and the sweep is restarted every time you change the frequency parameters.
The frequency range of a channel can be expressed by either of two groups of parameters: Start
Frequency and Stop Frequency（
fstart/fstop）; or Center Frequency and Span（fcenter/ fspan）. If any
of the parameters is changed, the others would be adjusted automatically in order to ensure the
coupling relationship among them:

Center Freq
Set the center frequency of the current channel. Press this key to switch to center frequency input
mode and the center frequency is displayed at the lower left and right sides of the grid
respectively.
Key Points:
• The start and stop frequencies vary with the center frequency when the span is constant.
• Changing the center frequency horizontally shifts the current channel and the adjustment is
limited by the specified frequency range.
• In Zero Span mode, the start frequency, stop frequency and center frequency are always
the same.
• You can modify this parameter using the numeric keys, knob or direction keys. Refer to
“Parameter Setting” for more details.

Set the step of center frequency. Changing the center frequency in a fixed step continuously
switches the channel to be measured. Key Points:
• The CF step can be set in “Manual” or “Auto” mode. In Auto mode, the CF step is 1/10 of the
span in Non-zero span mode or equals the RBW while in Zero span mode; in Manual mode,
you can set the step using the numeric keys.
• After you set an appropriate CF step and select Center Freq, use up and down direction keys
to switch between measurement channels in a specified step in order to sweep the adjacent
channel manually.
• You can modify this parameter using the numeric keys, knob or direction keys. For more

3.1.2 SPAN
Set the span of the analyzer. The change of this parameter will affect the frequency parameters
and restart the sweep.
Span
Set the frequency range of the current channel. Press this key to switch to center frequency/span
input mode and the center frequency and span are displayed at the lower left and right sides of
the grid respectively.
Key Points:
• The start and stop frequencies vary with the span automatically.
• In manual span mode, the span can be set down to 100 Hz (the only way into the zero-span
mode is pressing the Zero Span menu option) and up to the full span described in
“Specifications”. When the span is set to the maximum, the analyzer enters full span mode.
• Modifying the span in non-zero span mode may cause an automatic change in both CF step
and RBW if they are in Auto mode, and the change of RBW may influence VBW (in Auto
VBW mode).
• Variation in the span, RBW or VBW would cause a change in the sweep time.
• You can modify this parameter using the numeric keys, knob, or direction keys. For more
details, please refer to “Parameter Setting”.

Zero Span
Set the span of the analyzer to 0 Hz. Both the start and stop frequencies will equal the center
frequency and the horizontal axis will denote time. The analyzer measures the time domain
characteristics of the amplitude of the corresponding frequency point on the input signal. Key
Points: As opposed to the Non-zero span, the screen shows the time domain characteristics of
the fixed frequency component in zero span mode.The following functions are invalid in Zero span
mode:
“Zoom In” and “Zoom Out” in SPAN
Zoom In
Set the span to half of its current value. At this point, the signal on the screen is zommed in on to
observe signal details.
Zoom Out
Set the span to twice the current value. At this point, the signal on the screen is zoomed out on to
gain more information about the signal.
3.1.3 AMPT

• By changing the scale, the amplitude range available is adjusted.
Scale Type
Set the scale type of Y-axis to Lin or Log, the default is Log. Key Points:
• In Log scale type: the Y-axis denotes the logarithmic coordinate, the value shown at the top
of the grid is the reference level and each grid represents the scale value. The unit of Y-axis
will automatically switch to the default “dBm” in Log scale type when the scale type is
changed from Lin to Log.
• In Lin scale type: the Y-axis denotes the linear coordinate, the values shown at the top of the
grid and the bottom of the grid are the reference level and 0 V respectively. Each grid
represents 10% of the reference level and the Scale/Div is invalid. The unit of Y-axis will
automatically switch to the default “Volts” in Lin scale type when the scale type is changed
from Log to Lin.
• The scale type does not affect the unit of Y-axis.
Units
Set the unit of the Y-axis to dBm, dBmV, dBuV, Volts or Watts. Wherein, dBm, dBmV, and dBuV
are for Log scale; Volts and Watts are for Linear scale. The default is dBm.

Ref Offset
Assign an offset to the reference level to compensate for gains or losses generated between the
device under measurement and the analyzer.
Key Points:
The change of this value changes both the reference level readout and the amplitude readout of
the marker, but does not impact the position of the curve on the screen.
You can modify this parameter using the numeric keys. For more details, please refer to

3.2 Sweep and Function Settings
3.2.1 BW
Set the RBW (Resolution Bandwidth), VBW (Video Bandwidth) and detector type parameters of
the analyzer.
RBW
Set the desired resolution bandwidth in order to distinguish between signals which are close in
frequency.
Key Points:
• Reducing RBW will increase the frequency resolution, but will increase the sweep time
(Sweep Time is affected by a combination of RBW and VBW when it is in Auto mode).
• RBW decreases with the span (non-zero span) in Auto RBW mode.
• You can modify this parameter using the numeric keys, knob or direction keys. For more
details, please refer to “Parameter Setting”.
Note: if detector type is “Quasi-Peak” or filter type is “EMI”, RBW can be 200 Hz, 9 kHz or 120
kHz only.

Video Bandwidth
Set Video Bandwidth, shortform is VBW, to filter the noise out of the video band.
Key Points:
• Reduce VBW can make the spectral line be smooth, and the small signal which is submerged
in noise can stand out. But the scan time will be longer. (When scan time is automatic, it is
influenced by RBW and VBW together).
• When VBW is automatic, it changes with RBW. But it is not influenced by RBW when
manually.
• You can use numeric keys, knobs or direction keys to modify this parameter. The detail
method refers to the specification in “Parameter Setting”.

Chapter4 Test Case
Testing Low Level Signal
Testing Signal Distortion
4.1 Testing Low Level Signal
This section introduces how to test low level signal, and how to differentiate it with the
noice in the same spectrum. The following is three methods to test low level signal.
4.1.1 Reduce the Loss of Input
The ability of spectrum analyzer to test low signal is limited by the noice produced
internally. The level is influenced by input attenuator when signal passes the
spectrum analyzer. If the signal is very close to the bottom of noise, it can differentiate
the signal with the noice to reduce the loss of input.
1) Reset spectrum analyzer
2) Set the frequency of signal source and amplitude as 1 GHz and -80 dBm. Connect
the RF OUT port of signal source to the RF IN port of spectrum analyzer and turn
on the signal output.
3) Set center frequency, span and reference level:
Press FREQ → 1GHz
Press SPAN → 5MHz
Press AMPT→ - 40dBm
4) Move the peak value that needed to the center of screen.
Press MARKER → Peak
1) Reduce the span to 1 MHz. If need, move the peak value to the center of screen
again.
Press SPAN →1 MHz
2) Set the attenuation as 20 dB. Pay attention that when the attenuation increases,
the bottom of noice will be more close to signal level.
Press AMPT→Attenuation→ 20dB
3) Press AMPT →Attenuation→ 0 dB, set the attenuation as 0 dB.
4.1.2 Reduce the Resolution Bandwidth
The internal noice level is influenced by resolution bandwidth, but continuous wave
signal is not. Decrease RBW into 10%, and the bottom noise will also decrease 10
dB.
1) Reset spectrum analyzer
2) Set the frequency of signal source and amplitude as 1 GHz and -80 dBm.
Connect the RF OUT port of signal source to the RF IN port of spectrum
analyzer and turn on the signal output.
3) Set center frequency, span and reference level:
Press FREQ → 1GHz
Press SPAN → 5MHz
Press AMPT→ - 40dBm
4) Reduce resolution bandwidth.
Press BW, and press manual. The resolution bandwidth can be reduced by
knobs and arrow key. Because the noise level reduces, the low level signal
will be clearer, as following picture.
4.1.3 Trace Average
Taking the average is the digital processing. It is to plus current value in each trace
point and previous average value, and then take the average. Choose the operation
of taking average. When spectrum analyzer is doing the automatic coupling, it can
make the displayed noise level get smooth to change detection mode into sampling
mode.
1) Reset spectrum analyzer
2) Set the frequency of signal source and amplitude as 1 GHz and -80 dBm.
Connect the RF OUT port of signal source to the RF IN port of spectrum
analyzer and turn on the signal output.
3) Set center frequency, span and reference level:
Press FREQ → 1GHz
Press SPAN → 5MHz
Press AMPT→ - 40dBm
4) Press TRACE →Average (ON) to turn on the average function.
Press 100 → ENTER, set the number of average as 100. Because the
operation of taking the average will make the trace be smooth, and the low
level signal will be clearer.
4.2 Measuring Signal Distortion
This selection introduces how to recognize and measure signal distortion.
Recognize the distortion produced by spectrum analyzer.
The high level input signal may cause the distortion signal produced by spectrum
analyzer. This distortion signal will cover the true signal that needs to be measured in
the input signal. The user can recognize these signals through trace and RF
attenuator. If yes, this distortion is produced inside the instrument. In this case, we
use a signal output by a function generator as signal source to recognize whether the
harmonic distortion component is produced by spectrum analyzer.
1. Connect function generator to RF IN of spectrum analyzer. Set the input
frequency and amplitude of signal source as 200MHz, -10dBm.
2. Set center frequency and span of spectrum analyzer.
Press [PRESET] (to restore factory settings) •
Press [FREQ] → 400MHz
Press [SPAN] → 700MHz
The harmonic distortion component produced by this signal at the inputmixer of
spectrum analyzer (arranged in turn with original 200MHz signal at 200MHz
interval).
1. The center frequency should be changed as the frequency value at the first
harmonic wave.
Press [MARKER] → PEAK
2. Change the span as 50 MHz, and display the signal in the center of screen again.
Press [SPAN] → 50MHz
Press [MARKER] → PEAK
3. Set the attenuation as 0 dB：
Press [AMPT] → Attenuation → 0dB
4. To recognize whether the harmonic distortion component is produced by
spectrum analyzer, firstly display the input signal in trace 2：
Press [TRACE] → Trace 2
Press [TRACE] → Clear
5. Place a Delta mark in the harmonic distortion component of trace 2:
Press [MARKER] → peak
Press [MARKER] → Delta
6. Press [AMPT] → Attenuation → 10dB to turn up the RF attenuation to 10 dB.
The reading of amplitude difference is influenced by two factors:
1) To increase input attenuation will make signal to noise ratio (SNR) worse which will
cause the reading to be positive.
2) The loss of harmonic wave caused by internal circuit of spectrum analyzer will
make the reading to be negative. To set the input attenuation can produce minimum
reading.

5.1 SCPI Brief Introduction
SCPI (Standard Commands for Programmable Instrument) is an ASCII- based instrument
command language designed for test and measurement instruments, with the goal of reducing
automatic test equipment (ATE) program development time. SCPI accomplishes this goal by
providing a consistent programming environment for instrument control and data usage. This
consistent programming environment is achieved by the use of defined program messages,
instrument responses, and data formats across all SCPI instruments. By providing a consistent
programming environment, replacing one SCPI instrument with another SCPI instrument in a
system should require less effort than with non- SCPI instrument.
SCPI is not a standard which completely provides for interchangeable instrumentation. SCPI
helps move toward interchangeability by defining instrument commands and responses, but not
functionality, accuracy, resolution, and so forth.
5.1.1 Basic Knowledge Requirement
Programming with SCPI requires knowledge of:
• Computer programming languages, such as C or C++.
• The language of your instrument. A HAS Series spectrum analyzer employs SCPI as its
programming language.SCPI.
5.1.2 Command Syntax
Command syntax includes standard notations and statement rules.
Command Statement Rules Overview
• Command statements read from left to right
• Use either long form or short form of keywords, but do not use both
• No separating space between the keywords, only use a colon to separate keywords of
different levels
• Always separating a keyword from a variable with a space
• Always separating a variable from its unit with a space (if variable has a unit)
5.1.3 Standard Notations
A command consists of mnemonics (keywords), parameters and punctuation. Before you start to
program your analyzer, familiarize yourself with the standard notation of each of them.
Keywords
Many commands have both a long and a short form: use either one. (a combination of the two is
not allowed). Consider the: FREQuency command for example:
• Short form : FREQ
