Introduction of SDG5000 Series

The manual covers the following 3 types of SDG5000 Series

Function/Arbitrary Waveform Generators: SDG5082, SDG5122, SDG5162.

SDG5000 Series 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.

SDG5000 Series have 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, 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.

1.1. General Inspection

When you get a new SDG5000 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 whole machine 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.

Use the Mod button to generate modulated waveform.SDG5000 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%.

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.

SDG5000 User Manual 52

ASK

ASK is a form of modulation that represents digital data as variations in the amplitude of a carrier wave.

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

SDG5000 User Manual 79

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.
