Introduction of SDG1000 Series
The manual covers SDG1000 Series Function/Arbitrary Waveform
Generators.
SIGLENT SDG1000 Series Function/Arbitrary Waveform Generators adopt
the direct digital synthesis (DDS) technology, which can provide stable,
high-precision, pure and low distortion signals. Its combination of excellent
system features, easiness in usage and versatile functions makes this
generator a perfect solution for your job now and in the future.
SDG1000 Series Function/Arbitrary Waveform Generator has a clear and
simple front-panel. The user-friendly panel layout and instructions, versatile
terminals, direct graph interface, built-in instructions and help system have
greatly simplified the operation process, with the help of which, users do not
have to spend a great deal of time learning and familiarizing the operation of
the generator before they can use it proficiently. The built-in AM, FM, PM,
ASK, FSK and PWM modulation functions generate modulated waveforms at
ease, without the help of a separate modulating source. USB I/O is a
standard accessory, while GPIB is optional. Remote instructions meet the
SCPI specification requirements.
From the characteristics and specifications given below, you will understand
how SDG1000 can satisfy your requirements.
DDS technology provides precise, stable and low distortional output

2.7. To Generate the Modulated Waveform
Use the Mod button to generate modulated waveform.SDG1000 Series can
generate AM, FM, ASK, FSK, PM, PWM and DSB-AM modulated waveforms.
Modulating parameters vary with the types of the modulation. In AM, users
can set the source (internal/external), depth, modulating frequency,
modulating waveform and carrier waveform; In FM, users can set the source
(internal/ external),modulating frequency, frequency deviation, modulating
waveform and carrier waveform; In ASK, users can set the source
(internal/external), Key Freq and carrier waveform; In FSK, users can set the
source (internal/external), key frequency, Hop Freq and carrier waveform; In
PM, users can set the source (internal/external),phase deviation, modulating
frequency, modulating waveform and carrier waveform.
We will cover how to set these parameters in details according to the
modulation types.

Modulation Depth
The amplitude range (also called ‘Percentage Modulation’). Modulation depth
varies from 1% to 120%.
In the 0% modulation, the output amplitude is the half of the set one.
In the 100％ modulation, the output amplitude is the same with the set
one.
For an external source, the depth of AM is controlled by the voltage level of
the connector connected to the [Modulation In]. ±6V corresponds to the
currently set depth 100%.
FM
The modulated waveform consists of two parts: the carrier waveform and the

Frequency Deviation
The deviation should be equal to or less than the carrier waveform
frequency.
The sum of the deviation and the carrier frequency should be equal to or
less than maximum frequency of the selected function.
For an external source, the deviation is controlled by the voltage level of
the connector connected to the [Modulation In]. +6V corresponds to the
selected deviation and -6V to the negative selected deviation.

ASK
ASK is a form of modulation that represents digital data as variations in the
amplitude of a carrier wave. The amplitude of an analog carrier signal varies

To Set the Sync Output
The generator provides Sync output through the [Sync] connector on the rear
panel. All standard output functions (except DC and Noise) have a
corresponding Sync signal. For some applications, they can be disabled if
users do not want to use it,
In the default setting, the Sync signal should be connected to the [Sync]
connector (activated). When the Sync Signal is disabled, the output
voltage of the [Sync] connector is level low.
In the Inverse Mode, the Waveform that corresponds to the Sync Signal
does not inverse.
The Sync Signal is a Pulse Signal with fixed positive pulse width, which is
more than 50ns.
For non-modulated waveform, the Sync Signal reference is the carrier.
For internal modulating AM, FM and PM, the Sync signal reference is the
modulated signal (not the carrier signal).
For ASK and FSK, the Sync Signal Reference is the keying Frequency.
For a Sweep, when the sweep starts, the Sync Signal becomes TTL
Level High. The Sync frequency equals the specific Sweep time.
For the Burst, when the burst starts, the Sync Signal is Level High.
For the External Gated Burst, the Sync Signal follows the External Gated
Signal.
