2. INTRODUCTION
The GFG-8210A Function Generator is a stable low distortion
instrument which generate signals in the frequency range up to 10MHz.
Typical applications include a wide range of audio response testing
applications, vibration testing, servo system evaluation, ultra sound
applications, and etc.
The instrument includes the following features: logarithmic and linear
sweep capabilities, together with 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 for the response to be displayed. The
counter can be switched to measure and display the frequency of an
external signal up to 150MHz.
z ADDITIONAL FEATURES
1. Low distortion waveforms (sine, triangular and square).
2. Signal output in eight decade stages, 0.1Hz to 10MHz.
3. Adjustable sweep time and sweep width both in linear and
logarithmic modes.
4. Duty cycle control with signal inversion capability.
5. External Voltage controlled Frequency (VCF).
6. A second output for TTL or adjustable CMOS pulses.
7. 50 ohm main signal output with DC offset adjustment and 20dB
attenuation capability.
8. Supplied with two BNC test leads and AC power cord set.
