SDG800 User ManualVIntroduction of SDG800 Series
The manual covers the following three types of SDG800 Series
Function/Arbitrary Waveform Generators: SDG830,SDG810, SDG805.

SDG800 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 perfectsolution for your job now and in the future.

SDG800 Series Function/Arbitrary Waveform Generator has a clear andsimple front-panel. The user-friendly panel layout and instructions, versatileterminals, direct graph interface, built-in instructions and help system havegreatly simplified the operation process, with the help of which, users do nothave 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, DSB-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.

SDG800 User Manual11.1. General Inspection
When you get a new SDG800 Series Function/Arbitrary Waveform Generator,
you are suggested to take the following steps to inspect the instrument.

1. Inspect the shipping container for damage.
If there are damages in the packing or foam, keep them until the wholemachine and the accessories pass the electric and mechanical testing.

2. Check the accessories.
Accessories supplied with the instrument are listed in chapter 6‘Appendix A: Accessories’.
If the contents are incomplete or damaged, please notify your sales
representative.

3. Inspect the instrument.
In case any mechanical damage or defect, or if the instrument does notoperate properly or pass performance tests, notify your sales
representative. If the shipping container is damaged, or the cushioning
materials show signs of stress, notify the carrier as well as your sales
office. Keep the shipping materials for the carrier’s inspection. Offices
will arrange for repair or replacement at their option without waiting forclaim settlement.

To Set the Output Load

For the [Output] connector on the front panel, the generator has a built-in
50Ω series impendence. If the actual load does not match the set one,the displayed amplitude and offset will be incorrect. This function is used
to match the displayed voltage with the expected one.

2. To Set the Invert Waveform

Press Utility →Output Setup→ Invert, to set the Inverse Waveform Output.
When the waveform is inverse, no offset will change.

3. 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 acorresponding 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, theoutput 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 thecarrier.



For internal modulating AM, FM and PM, the Sync signal referenceis 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.

SDG800 User Manual67

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.

General Inspecting
After receiving a new SDG800 Series Function/Arbitrary Waveform
Generator, please inspect the instrument as followed:
1. Inspect the shipping container for damage.
Keep the damaged shipping container or cushioning material until thecontents of the shipment have been checked for completeness and the
instrument has been checked mechanically and electrically.

2. Inspect the whole instrument.
In case there is any mechanical damage or defect, or the instrument
does not operate properly or fails performance tests, notify the SIGLENT
sales representative.
If the shipping container is damaged, or the cushioning materials show
signs of stress, notify the carrier as well as the SIGLENT sales
department. Keep the shipping materials for carrier’s inspection.

3. Check the accessories.
Accessories supplied with the instrument are listed below. If the contents
are incomplete or damaged, notify the SIGLENT sales representative.
