3 MHz Function Generator

This is a stable low distortion instrument, which generates signals in the frequency range up to 3MHz. Typical applications include a wide range of audio response testing applications, vibration testing, servo system evaluation, ultra sound applications, etc. The GFG-8215A includes logarithmic and linear sweep capabilities and a built in frequency counter. The sweep capability simplifies the task of finding resonant points of speakers, filter networks and other networks / structures. An oscilloscope may be connected to this instrument to display the response. The counter can be switched to measure and display the frequency of an external signal up to 150MHz.
