4 MHz PULSE/ FUNCTION GENERATOR

Informação

The Wavetek model 187, a 4 MHz Pulse/Function Generator, is a precision source of sine, triangle, square and pulse waveforms plus dc voltage. All waveforms are front panel variable from 4 mHz to 4 MHz and can be frequency modulated and swept with an external signal. Variable width and delay, single or double pulses can be output inverted or normal. Amplitude of the waveforms is variable from 10V peak-to-peak into 50Ω down to 30 mV peak- to-peak. DC reference of the waveform can be offset positively or negatively. The two selectable waveform outputs are a 20V peak- to-peak maximum and a 2V peak-to-peak maximum (20 dB down from 20 Vp-p); both may be varied over a 30 dB range. A TTL level signal at Generator frequency is simultaneous with the waveform outputs for synchronization.
