CS700 Signal Generator

The CS700 Signal Generator is a plug-in module for the CS328 and CS320 Oscilloscopes. It can be factory fitted if ordered with a CS320 or CS328 or it can be fitted later by the user.

The CS700 Signal Generator generates sine, square and triangle output waveforms. The amplitude may be varied between 0 and 5V pk-pk, in 10mV steps. The offset may be varied from 4 to +4V in 10 mV steps. The generator can be modulated (FSK or PSK) and frequency swept. The sweep may be synchronized with the Spectrum Analyser to carry out transfer response measurements. Two of the digital inputs may be allocated to switch between either of the two frequencies or two phases.
