Saelig has introduced the Rigol DG800 Pro/DG900 Pro Function/Arbitrary Waveform Generators which feature up to 625/1250MSa/s sampling and 2/16Mpts/ch memory depth with 16-bit precision.

They are cost-effective function/arbitrary waveform generators that combine multiple functions including Function Generator, Arbitrary Waveform Generator, White Noise Generator, Pulse Generator, Harmonic Generator, Analog/Digital Modulator and Counter. The 7-digit counter has a maximum frequency input of 500MHz/1GHz, while the signal generator output, with its peak output of 20Vpp, features a wealth of internal and external modulation types, including Sweep, AM, FM, PM, ASK, FSK, PSK, and PWM. 148 built-in waveforms are available for engineering, medical, automobile, math, and other fields, and sequences of up to 64 waveforms can be created. 

With their compact size (10.5” x 6.5” x 3.2”) and convenient 7” capacitive colour touchscreen, these instruments are very portable, making them useful for a wide range of working environments. These test instruments feature rear-panel VESA mount capability for saving valuable desk space, while for field use, they can be powered externally from a USB-C interface.
