DDS function generators

23 January 2013 Test & Measurement

The digimess FG300 series of general purpose direct digital synthesis (DDS) function generators provides frequencies to 3 MHz (FG303) and 8 MHz (FG308) with 100 mHz resolution. Frequency setting is by keypad entry or rotary control, and the combination of soft touch buttons and rotary controls for the remaining features result in an easy to use instrument.

The generators have a 6-digit frequency display for internal or external signals and a 4-digit output amplitude display. They also have an output on/off switch and a variable TTL/CMOS amplitude control. Further features include LED indicators for frequency, amplitude and attenuation ranges as well as the selected waveform shape.

The instruments are capable of producing sine, square and triangle waveforms at levels from 20 mV to 20 V peak-to-peak. DC offset is adjustable to ±10 V and duty cycle from 20% to 80%.
