Nida Model 442
Function Generator
Description
The Nida Model 442 Function Generator provides the student with an instrument for generating external signal sources. The Model 442 provides Sine, Triangle, Square, ±Pulse, and ±Ramp waveforms with a frequency range of 0.2 Hz to 20 MHz. A continuously variable DC offset allows the output to be injected directly into circuits at the correct bias level. A variable duty cycle permits the adjustment of pulse and ramp signals. For added versatility, this model includes amplitude and frequency modulation. Measurement modes and ranges are front panel selectable and are presented by Computer Assisted Instruction (CAI), as well as the hardcopy text experiments for the Nida training programs.
