Function and Signal Generators

Function and signal generators are test instruments that produce waveforms such as sine, square, ramp and pulse at a set frequency and amplitude. They are used to apply a known input signal to a circuit when testing amplifier, filter and sensor circuits, in communication and embedded system development, and in training laboratories. The category includes single- and dual-channel models such as the Unit UTG932E, UTG1010A, UTG2025A, UTG2082B, UTG2122B and UTG4162A; the product data includes 14- and 16-bit vertical resolution, sampling rates such as 125 MSa/s, 200 MSa/s and 500 MSa/s, and modulation types such as AM, FM, PM and FSK. Compare the highest frequency you need to produce, the channel count, the sampling rate and vertical resolution, the modulation types, the sweep and burst modes, and the built-in frequency counter. For waveforms such as square and ramp, the upper frequency limit is lower than for sine; the ramp frequency range in the product data shows this. A function generator produces a test signal; it does not replace the oscilloscope that displays the signal or the power supply that feeds the circuit.

How to choose Function and Signal Generators

Function and signal generators are test instruments that produce waveforms such as sine, square, ramp and pulse at a set frequency and amplitude. They are used to apply a known input signal to a circuit when testing amplifier, filter and sensor circuits, in communication and embedded system development, and in training laboratories.

  • Identify the measurement or fastening task and the required insulation safety rating.
  • Select jaw profile, cross-section range and accessories for the conductor or fastener standard.
  • Check CAT voltage category and replacement tip or die availability for field conditions.
