Siglent SDG1025 25MHz Arbitrary Waveform Generator Review & Features

High Level Performance for a Reasonable Price

Shipped & Supported from the USA

3 Year limited warranty

The SDG1025 Function/Arbitrary Waveform Generator represents a new level of price performance  value from SIGLENT.  The ergonomic design features a 3.5 inch TFT-LCD display;  Online help feature; Support for USB and internal storage to accomodate file management; . The SIGLENT SDG1025 implements a  DDS  ( Direct Digital Synthesizer) design which provides several technical advantages over older analog Function/Waveform generators including enhanced frequency agility, better phase noise and more precision to control the output phase across frequency switching transitions. 

Arbitrary Waveform Generation Capabilities:

The SIGLENT SDG1025 generates 14-bit 16kpts arbitrary waveforms, Arbitrary editing software (EasyWave) provides 9 standard waveforms: Square, Sine, Pulse, Ramp, Exponential Fall, Exponential lRise, Sinc, Noise and DC, which meets’ basic needs of all engineers; It is easy to 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 the engineer  edit multiple-waveforms at the same time. It provides ten (10) Storage locations in non-volatile RAM. You can edit and store more waveforms on your PC by using the EasyWave sofware.

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 .
