Wavetek MODEL FG3B
* Sine, square, triangle, TTL & CMOS outputs
* 7 Frequency ranges from 0.2Hz to 2MHz * Linear or Logarithmic sweep z
* Internal/external AM or FM * Built-in 5-Digit frequency counter with external input.
* Voltage controlled frequency (VCF)* Switchable 20dB output Attentuator * Variable duty cycle
The FG3B Sweep Function Generator features outstanding versatility and performance with five signals available: sine wave, triangle wave, square wave, TTL and CMOS pulse outputs. The FG3B can provide linear or logarithmic sweep of any of the selected signal outputs, or perform either amplitude or frequency modulation with internal or external modulating frequencies. Duty cycle control allows the 50% duty cycle of the output signals to be changed to any desired value, which can be used to produce short duration pulses or sawtooth (ramp) signals. The invert button allows you to change polarity of the signal. A built-in 5-digit frequency counter eliminates the need to connect an external counter for accurate verification of frequency settings. In addition, it can be used as a stand alone counter for measuring external signals up to 10MHz with excellent accuracy and 25mV sensitivity. A voltage controlled frequency option allows the user to vary frequency as a function of the VCF input. A switchable 20dB output attentuator is available where low signal levels are needed.
