Carefully read the following safety precautions to avoid any personal injury or damage to
the instrument and any products connected to it. To avoid potential hazards, please use the
instrument as specified.
Use Proper AC Power Line
Only the power cord designed for the instrument and authorized by the local country
should be used.
Ground the Instrument
The instrument is grounded through the protective earth conductor of the power line. To
avoid electric shock, please make sure the instrument is grounded correctly before
connecting its input or output terminals.
Connect the Probe Correctly.
If a probe is used, do not connect the ground lead to high voltage since it has an isobaric
electric potential as the ground.
Look Over All Terminals’ Ratings
To avoid fire or electric shock, please look over all ratings and sign instruction of the
instrument. Before connecting the instrument, please read the manual carefully to gain
more information about the ratings.
Use Proper Overvoltage Protection
Make sure that no over-voltage (such as that caused by a thunderstorm) can reach the
product, or else the operator might be exposed to danger of electrical shock.
Electrostatic Prevention
Operate the instrument in an electrostatic discharge protective area environment to avoid
damages induced by static discharge. Always ground both the internal and external
conductors of the cable to release static before connecting.
Maintain Proper Ventilation
Inadequate ventilation may cause increasing of the instrument’s temperature, which will
eventually damage the instrument. So keep well ventilated and inspect the intake and fan
regularly.
Avoid Exposed Circuit or Components
Do not touch exposed contacts or components when the power is on.
Do Not Operate Without Covers
Do not operate the instrument with covers or panels removed.
Use Only the Specified Fuse.
Keep Product Surfaces Clean and Dry.
To avoid the influence of dust and/or moisture in the air, please keep the surface of the
device clean and dry.
Do Not Operate in Wet Conditions.
In order to avoid short circuiting to the interior of the device or electric shock, please do not
operate the instrument in a humid environment.
Do Not Operate in an Explosive Atmosphere.

2.2.1.4 Average Type
Choose one of the following averaging types: log power (video), power (RMS), or voltage
averaging. When trace average is on, the average type is shown on the left side of the display.
1. Log Power
Select the logarithmic (decibel) scale for all filtering and averaging processes. This scale is
"Video" because it is the most common display and analysis scale for the video signal within a
analyzer. This scale is excellent for finding Sine/CW signals near noise.
2. Power Average
In this average type, all filtering and averaging processes work on the power (the square of the
magnitude) of the signal, instead of its log or envelope voltage. This scale is best for
measuring the true time power of complex signals.
3. Voltage Average
In this Average type, all filtering and averaging processes work on the voltage of the envelope
of the signal. This scale is good for observing rise and fall behavior of AM or pulse-modulated
signals such as radar and TDMA transmitters.
2.2.1.5 Filter
Set the RBW filter type. The analyzer supports two kinds of RBW filters: “Gauss” (-3 dB

maximum level is detected in successive sweeps. Max Hold is very effective when measuring
events that may take successive scans to measure accurately. Some common applications
include FM Deviation, AM NRSC, and frequency hopping or drift.
3. Min Hold
Display the minimum value from multiple sweeps for each point of the trace and update the
data if a new minimum is generated in successive sweeps.
4. View

Set the number of averages of the selected trace.
More averages can reduce the noise and the influence of other random signals; thus
highlighting the stable signal characteristics. The larger the number of averages is, the
smoother the trace will be. Enabling averaging increases the length of time to collect the full
spectral information because the analyzer will need to execute the sweep count that
corresponds to the average setting. The displayed data is averaged in a first-in-first-out

processed data (a single data point) on the screen.
Select an appropriate detector type according to the actual application in order to ensure the
accuracy of the measurement.
The available types are Pos Peak, Neg Peak, Sample, Normal, Average and Quasi Peak.
The default is Pos peak.
1. Positive Peak
For each trace point, Positive Peak detector displays the maximum value of data sampled
within the corresponding time interval.
2. Negative Peak
For each trace point, Negative Peak detector displays the minimum value of data sampled
within the corresponding time interval.
3. Sample
For each trace point, Sample detector displays the transient level corresponding to the central
time point of the corresponding time interval. This detector type is applicable to noise or
noise-like signal.
4. Normal
Normal detector (also called rosenfell detector) displays the maximum value and the minimum
value of the sample data segment in turn: Odd-numbered data points display the maximum
value and even-numbered data points display the minimum value. In this way, the amplitude

5. Average
For each trace point, Average detector displays the average value of data sampled within the

6. Quasi-Peak
Quasi-Peak (QP) detector, which is a weighted form of peak detector, is used for EMC pulse
testing. The SVA QP detector is designed to follow CISPR-16 response specifications. For a
single frequency point, the detector detects the peaks within the QP dwell time.
The peaks detected are weighted using a digital model that follows a defined response curve
as well as the time constant specified in the CISPR 16 standards. The measurement time for
QP is far longer than Peak Detector.

can be set in “Auto” or “Manual” mode and the default is “Auto”.
In non-zero span, the analyzer selects the shortest sweep time on the basis of the current
RBW and VBW settings if Auto is selected.
Decreasing the sweep time will decrease measurement time. However, an error may be
caused if the specified sweep time is less than the minimum sweep time in Auto coupling;
at this point, “UNCAL” is shown in the status bar on the screen. Measurements taken with
“UNCAL” showing may not meet the specifications of the instrument and can have

2.3 Marker
2.3.1 Marker
The marker appears as a rhombic sign (as shown below) for identifying points on a trace. You
can easily read the amplitude, frequency and sweep time of the marked point on the trace.
The analyzer allows for up to eight/four pairs of markers to be displayed at one time, but
only one pair or a single marker is active every time.
You can use the numeric keys, knob or direction keys to modify the desired frequency or
time as well as view the readouts of different points on the trace.
2.3.1.1 Select Marker
Select one of the four markers. The default is Marker1. When a marker is selected, you can set
its type, trace to be marked, readout type and other related parameters. The enabled marker
will appear on the trace selected through the Select Trace option and the readouts of this

One of the marker types. It is used to measure the X (Frequency or Time) and Y (Amplitude)
values of a certain point on the trace. When selected, a marker with the number of the current
marker (such as “1”) appears on the trace.
If no active marker exists currently, a marker will be enabled automatically at the center
frequency of the current trace.
You can use the numeric keys, knob or direction keys to move the marker. The readouts
of the marker will be displayed at the upper right corner of the screen.
SIGLENT
SVA1000X User Manual 42
The readout resolution of the X-axis (frequency or time) is related to the span. For higher
readout resolution, reduce the span.
2.3.1.4 Delta
One of the marker types. It is used to measure the delta values of X (Frequency or Time) and Y
(Amplitude) between the reference point and a certain point on the trace. When selected, a
pair of markers appears on the trace: Fixed Related Marker (marked by a combination of the
marker number and letter “+”, such as “2+”) and the Delta Marker (marked by the “∆”, such as
“1∆2”).
After the marker selects “Delta”, the original marker will become the delta measurement
marker, and the related marker of the incrementing sequence number will become the
reference “fixed” marker
The delta marker is in the "relative to" state, and its X-axis position can be changed; the
related marker is in the "fixed" state by default (the X-axis and Y-axis positions are fixed),
but the X-axis can be adjusted by changing to the "normal" state.
The first row in the upper right corner of the trace area shows the frequency (or time)
difference and amplitude difference between the two markers; the second row in the
upper right corner of the trace area shows the X axis and amplitude value of the related
marker.
2.3.1.5 Fixed
One of the marker types. When “Fixed” is selected, the X-axis and Y-axis of the marker will not
change by the trace and can only be changed through the menu. The fixed marker is marked
with "+".
After the marker selects “Delta”, the original marker will become the delta measurement
marker, and the related marker of the incrementing sequence number will become the
reference “fixed” marker
2.3.1.6 Off
Turn off the marker currently selected. The marker information displayed on the screen and
functions based on the marker will also be turned off.
2.3.1.7 Relative To
“Relative to” is used to measure the delta values of X (Frequency or Time) and Y (Amplitude)
between two markers which can mark on different traces.
After the marker selects “Delta”, the original marker will become the delta measurement
marker, and the related marker of the incrementing sequence number will become the

The range of this distance is limited by the velocity factor and is proportional to the velocity
factor. When the velocity factor is 1, the length that can be measured is the maximum.

Parameter
Explanation
Default
34.00 m
Unit
m, feet
Selecting the appropriate frequency span (= start freq – stop freq) is not as obvious as it may
seem. The resolution and maximum distance range are dependent upon the span, the number
of frequency data points and the velocity factor of the cable. Therefore, the frequency span
SIGLENT
SVA1000X User Manual 71
must be chosen carefully.
There is a constraint that limits the frequency range:
The wider the span is, the smaller the maximum distance that can be measured. In another
words, long distance measurements require small span settings.
Meanwhile, there is also a relationship between resolution and the span.
The wider the span is, the smaller the resolution. Wider frequency sweeps improve the
resolution of DTF measurements.

Set the attenuation factor of the cable-under-test. It is used to compensate the amplitude of

has been attenuated by the cable, thus the amplitude of peaks cannot show exactly where the
mismatch position is. So the cable atten is used to compensate by length.

included in PC’s OS initially.
Socket LAN is a method used to communicate with the analyzer over the LAN interface using
the Transmission Control Protocol/Internet Protocol (TCP/IP). A socket is a fundamental
technology used for computer networking and allows applications to communicate using
standard mechanisms built into network hardware and operating systems. The method
accesses a port on the analyzer from which bidirectional communication with a network
computer can be established.
Before you can use sockets LAN, you must select the analyzer’s sockets port number to use:
Standard mode: Available on port 5025. Use this port for programming.
Telnet mode: The telnet SCPI service is available on port 5024.
