The SDG1050 Function/Arbitrary Waveform Generator is a terrific addition to the SIGLENT family of arbitray waveform generators. The ergonomic friendly design features a 3.5 inch TFT-LCD display; Built-in Chinese/English language selector; Online help function; Support for USB and internal storage to facilitate file management; Special connection terminal for grounding. The SIGLENT SDG1050 utilyzes DDS (Direct Digital Synthesizer) technology and provides many technical advantages over older analog Function/Waveform generators including much improved frequency agility, improved phase noise and more precision when controlling the output phase across frequency switching transitions.

Arbitrary Waveform Generation Capabilities:

The SDG1050 generates 14-bit 16kpts arbitrary output waveforms, Arbitrary editing software (EasyWave) provides 9 standard waveforms: Sine, Square, Ramp, Pulse, ExRise, Exponential Fall, Sinc, Noise and DC, which meets all engineers’ basic needs; Develop your own waveforms using EasyWave drawing software with your computer mouse. Supports point-to-point line segment drawing and arbitrary point drawing.making it easy to create complex waveforms. Multi-file screen management helps users edit multiple-waveforms simultaneously. It provides 10 Storage locations in non-volatile RAM. You can edit and store more waveforms on your PC by using EasyWave.

Arbitrary waveform output:

Built-in 48 arbitrary waveforms, including math, engineering and other commonly-used waveforms.

Complete set of modulation functions, sweep output, burst output.

Complete set of modulation functions: AM, DSB-AM, FM, PM, FSK, ASK, PWM, the modulation waveform can be observed directly, which it is desirable for education and training sessions;
Sweep output: varies output frequency from start frequency to stop. Sweep time range: 1ms~500s. The carrier can be Sine, Square, Triangle and Arbitrary waveforms.
Burst output: It can periodically generate pulse sequences. Internal counter and external control signal are available to control burst output.

Dual-channel Synchronization:

Duplicating function

Channel coupling: after setting the primary channel and coupling frequency/phase differences, the frequency/phase of the second channel will change in relation to the primary channel, maintaining the frequency /phase difference .
Channel duplicating: allows user to duplicate parameters from one channel to the other.

Built-in frequency counter:

Wide frequency range: 0.1Hz~200MHz. Measurable parameters: frequency, period, duty-cycle, positive pulse width, negative pulse width Ssetting: Adjustable parameters include DC/AC coupling, trigger level and high frequency rejection.
