Introduction of SDG1000 Series

The manual covers the following 5 types of SDG1000 Series

Function/Arbitrary Waveform Generators: SDG1005, SDG1010, SDG1020,

SDG1025, SDG1050.

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.

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.

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%. z In the 0% modulation, the output amplitude is the half of the set one. z In the 100% modulation, the output amplitude is the same with the set one. z 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 modulating waveform. In FM, the frequency of the carrier waveform varies with the instantaneous voltage of the modulating waveform. The parameters for the FM are as shown in Figure 2- 30.

Frequency Deviation

z The deviation should be equal to or less than the carrier waveform frequency. z The sum of the deviation and the carrier frequency should be equal to or less than maximum frequency of the selected function. z 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 in accordance with the bit stream (modulating signal), keeping frequency and phase constant. The parameters for the ASK are as shown in Figure 2- 32

1. 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.

Steps for setting the load:

Press Utility →Output Setup→ Load, to enter the following interface.

Please note that the load parameter shown on the right bottom is the default setting when the power is on or the pre-set load value. If the current value is valid for the output, then current value will be used.

Figure 2- 59 Set the Output Load

Instruction

SDG1000 Series has a fixed 50Ω Series Impendence. No matter what value the set parameter is, if the real load is different from the set one, the displayed voltage will not equal the real voltage.

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 a corresponding Sync signal. For some applications, they can be disabled if users do not want to use it, z 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. z In the Inverse Mode, the Waveform that corresponds to the Sync Signal does not inverse. z The Sync Signal is a Pulse Signal with fixed positive pulse width, which is more than 50ns. z For non-modulated waveform, the Sync Signal reference is the carrier. z

For internal modulating AM, FM and PM, the Sync signal reference is the modulated signal (not the carrier signal). z For ASK and FSK, the Sync Signal Reference is the keying Frequency. z

For a Sweep, when the sweep starts, the Sync Signal becomes TTL Level

High. The Sync frequency equals the specific Sweep time. z For the Burst, when the burst starts, the Sync Signal is Level High. z

For the External Gated Burst, the Sync Signal follows the External Gated

Signal.
