Siglent SDG1025 25MHz Arbitrary Waveform Generator

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.

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.
