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.
