The signals available include sine wave, triangle wave, square wave, TTL pulses and CMOS pulses. The FG3C provides linear or logarithmic sweep of any of the selected signal outputs and performs either amplitude or frequency modulation with internal or external modulating frequencies. Duty-cycle control allows the 50% duty-cycle of output signals to be changed to any desired value. This produces short duration pulses or sawtooth (ramp) signals. An invert button allows you to quickly change the polarity of the signal. Its built-in, LED digital display frequency counter eliminates the need to connect an external counter to verify frequency settings. In addition, the LED counter can be used as a stand-alone counter for measuring external signals up to 150MHz. A voltage controlled frequency (VCF) feature allows you to vary the frequency as a function of the VCF input. A switchable 20dB output attenuator is available where low signal levels are needed. The FG3C is housed in a modern case with a dual-purpose carrying handle-tilt stand for both portable and bench-top applications. The instrument comes complete with test leads, Operator’s Manual (Multi-lingual: English, Spanish, French and German), spare fuse and a removable power cord.
