CS700A
Signal Generator (0-10MHz, Sine, Square, Triangle)
The CS700A Signal Generator is a plug-in module for the CS328A and CS320A Oscilloscopes. If you order at the same time as a CS328A or CS320A, the module will be factory fitted. The CS700 and CS700A have similar specifications but will only work in the relevant systems. "A" versions have serial numbers starting from 4000 The CS700A 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 maybe varied from –4 to +4V in 10 mV steps. The generator can be FSK and PSK modulated, and Frequency swept. The sweep may be synchronized with the Spectrum Analyser to carry out transfer response measurement. Two of the digital inputs may be allocated to switch between either of the two frequencies or two phases. Specifications:
