SIGLENT SDG7000A Series Arbitrary Waveform Generators

Product Overview
SIGLENT’s SDG7000A is a family of dual-channel Arbitrary Waveform Generators that feature up to 1 GHz bandwidth, a maximum sample rate of 5 GSa/s and 14-bit vertical resolution. It can generate arbitrary waveforms point by point with a maximum 2.5 GSa/s sample rate and vector signal with a maximum 500 MS/s.
It also has the ability to generate a variety of signals such as continuous wave, Pulse, Noise, PRBS patterns, and a 16-bit digital bus. It supports the generation of complex signals such as modulation, sweeping, bursting and dual channel copying/coupling/tracking and superposition. The output are differential/single-ended and support a maximum output range of ± 24 V. The instrument can ensure a large amplitude under high-frequency which eliminates an external power amplifier in some applications and addresses a wider range of requirements.

Characteristics

Multi-functional Waveform Generator
 

The SDG7000A series integrates multiple waveform generator functions from DC to continuous waves up to 1 GHz, which can replace RF signal generators in some applications. It adopts Siglent’s TrueArb point by point arbitrary waveform generation technology, whic h enables user adjustable output sample rates from 0.01 Sa/s to 2.5 GSa/s with excellent jitter performance and the generation of I/Q vector signals with a maximum settable bandwidth greater than 500 MHz. Using the benefits of Siglent’s EasyPulse architect ure, a low jitter pulse with a minimum pulse width of 1 ns can be generated. The SDG7000A also features a Gaussian noise output with adjustable bandwidth, Pseudo random code generation, an optional 16 channels of digital signal output for synthesizing digi tal communications, and much more.



Wide Range Amplitude Output
 

24Vpp analog output superimposed with ±12 Vdc offset, providing a maximum output range of ± 24 V (48 V).

Excellent Arbitrary Waveform Generation

AFG mode uses traditional DDS technology to generate arbitrary waveforms.
AWG mode uses the innovative TrueArb technology, with an adjustable sample rate from 0.01 Sa/s~ 2.5 GSa/s and jitter less than 20 ps. It not only has all the advantages of traditional DDS technology, but also overcomes its intrinsic jitter and distortion defects. The flexible platform also provides zero order hold, linear and sinc interpolation methods for increased flexibility when creating complex waveforms.

Sequence editing and playback The SDG7000A supports up to 1024 arbitrary wave segments, each of which can be set with a maximum of 65535 repetitions. When switching between segments, the output seamlessly moves from the last point of the previous segment to the first point of the next segment without generating an idle level. It is suitable for applications with high requirements for waveform switching.

EasyWaveX Supports extensive arbitrary wave editing functions including manual, linear, coordinate, and equation drawing that facilitate rapid generation of the required waveforms. The EasyWaveX editing software is embedded in the SDG7000A, and can also be installed in a computer, interacting with the SDG7000A over USB or LAN interfaces.

High-Speed Low Jitter Pulse
 

Low jitter When a Square/Pulse waveform is generated by traditional DDS, there can be additional jitter if the sample rate is not an integer-related multiple of the output frequency. EasyPulse technology successfully overcomes this weakness in DDS designs and helps to produce low jitter Square/Pulse waveforms.

High speed The minimum 1 ns pulse width, can be generated at any frequency. The pulse width can be finely adjusted in steps of 10 ps.

Flexible edge Adjustable fine step resolution to 100 ps. The minimum edge is 500 ps and can be generated at any frequency. The rising/ falling edge can be set respectively and can be used to generate asymmetric pulse.

Vector Signal Output (Optional)

The SDG7000A can generate common modulation types of IQ signals, such as ASK, FSK, PSK, QAM. With the innovative resampling technology, excellent EVM performance can be obtained at any symbol rate between 250 S/s ~ 500 MS/s. The built-in digital quadrature modulator can modulate the carrier of the IQ signal to any frequency between 0 Hz~1 GHz. The EasyIQ software can be used to generate and edit various types of IQ signals.

Complex Signal Generator
 

Modulation A variety of analog and digital modulation modes such as AM, FM, PM, FSK, ASK, PSK, DSB-SC, and PWM are supported. There are three modulation sources: Internal, External, and Channel.

Sweep and Burst Sweep supports "Line" and "Log" modes, while Burst enables "NCycle" and "Gated" modes. Both Sweep and Burst support trigger sources: Internal, External, and Manual.

Harmonics Function Provides the ability to add higher-order elements to your signal.

16 Channel Digital Output (Optional)

Purchase the corresponding digital bus kit to get 16-channel LVTTL or LVDS output with a bit rate of 1 μbps ~ 1 Gbps. Combine the digital bus with the analog channels to realize mixed-signal outputs.

Enhanced Dual Channel Functionality

Two Dual-Channel Operation Mode
 

Independent mode Enables the two channels to be used as two independent generators. Independent mode also eliminated the discontinuity on the output when parameters (frequency, amplitude) change.

Phase-Locked mode Automatically aligns the phases of each output.

Track/Copy/Coupling The track, copy and coupling functions between the two channels can quickly transfer the parameters of one channel to the other according to the requirements, greatly simplify the operation and meet the requirements of fast and synchronous switching waveforms.

Waveform Combining Superimposes CH1 and CH2 waveforms internally and provides the combined waveform to a user-selected output. It easily combines basic waveforms, random noise, modulation signals, sweep signals, burst signals, EasyPulse waveforms, and TrueArb waveforms without external connections or complex editing.

Channel Modulation One channel can modulate the other without external connections. This feature provides an easy method for complex modulation waveform creation. The modulating wave channel can be directly output and compared with the modulated signal.
