Product Description:
The model FG3B Sweep/Function Generator is a stable, low distortion instrument, capable of generating signals in the 0.2Hz to 2.0MHz frequency range. It is suitable for vibration testing, servo system evaluation, general-purpose audio response testing, ultrasound applications and much more.
Features that make this instrument unique include linear or logarithmic sweep capabilities and a built-in frequency counter. The sweep capability simplifies the often tedious task of finding resonant points in speakers, filters, and structures. You may connect an oscilloscope to the equipment and observe a display of responses automatically. The counter makes it easy to set the frequency control knob to the precise value desired. In addition, the counter may be switched to measure and display external signals up to 100MHz.
Other features include:
- Low-distortion sine wave, triangle wave, square wave and ramp signals.
- Signal outputs in seven decade increments from 0.2Hz to 2.0MHz.
- Adjustable sweep time, sweep width and linear/log sweep mode controls.
- AM and FM capability with internal or external modulation control.
- Duty cycle control with inversion feature.
- External VCF (Voltage Controlled Frequency).
- Main signal 50 Ohm output with DC offset adjustment and 20dB attenuation capability.
- Second output for TTL or adjustable CMOS pulses.
- Self-extinguishing plastic case, two BNC test cables and AC power cord.
