Special Features

True Arb Technology

With SIGLENT's TrueArb technology, the generator retains the advantages of DDS technology while overcoming the serious weaknesses of DDS jitter and distortion. Because TrueArb technology generates arbitrary waveform in a point-by-point fashion, every data point is used to generate the output signal which has been stored in memory. Date points will not missed or repeated and arbitrary waveforms possess very low jitter (< 150 ps). It supports any 8 pts ~ 8 Mpts Arb waveform with a sampling rate in a range of 1 μSa/s ~ 75 MSa/s.

Easy Pulse Technology

The innovative EasyPulse technology is capable of generating lower jitter Square or Pulse waveforms, brings a wide range and extremely high precision in pulse width and rise/fall times adjustment. When a Square/Pulse waveform is generated by DDS, there will be a one-clock-jitter if the sampling 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.

Rich Modulation Features

A wide range of analog and digital modulation modes are supported, including "internal" and "external" modulation. Supported modulation types: AM, FM, PM, FSK, ASK, DSB - AM

Burst Function

Burst signal for sine, square, ramp, pulse or arbitrary waveforms can be generated. Start phase ranges from 0° to 360° and burst period ranges from 1 µs to 1000s are supported, as well as two burst modes "N cycle" and "Gated”.

Sweep Function

Supports both logarithmic and linear sweep modes with "up" or "down" sweeping using one of the following waveforms: sine, square, ramp and arbitrary waveform. In sweep mode it can generate signals with variable frequency in a sweep time range from 1 ms to 500 s. The trigger source could be selected from internal, external and manual trigger.

Frequency Counter

The devices have a built-in high precision frequency counter with an input frequency range of 0.1 Hz to 200 MHz. Because of the separate input connector the frequency counter is independent of the two output channels.
