SG1639A Function Generator with Frequency Counter

Function Generator with Frequency Counter

Model: SG1639A

SG1639 series instrument is a kind of precise function generator / counter, the frequency range of main generator is from 0.02Hz to 3MHz (SG1639A) and 0.05Hz to 6MHz (SG1639B). The digital frequency counter can show the operating frequency of generator and test EXT signal’s frequency which less than 15MHz.

This unit can be replaced for sine wave generator, square wave generator, triangle wave generator and the frequency counter with the broad frequency range. And so, it is especially suitable for the teaching, science research and experiment about electron circuit and pulse circuit.
