1.5 Mhz square wave programmable frequency generator.

Out of stock


Note: Due to components shortages, the F125 is no longer available. The F165 is still available and programs written for the F125 run without any modifications on the F165. The F165 has all the features (and more) of the F125 and is fully compatible with the F125.


The F125 can run standalone up to 1500 program files copied from a PC or Mac. It is also possible to connect the F125 to a computer via a USB port and control it with the F100 software.

Note 2: The F125 has 2 independent internal frequency generators (A,B) and 2 BNC output connectors (1,2). A programmable multiplexer allows you to assign any internal channel(s) to any external BNC output(s) in any combination. For example, BNC connectors 1 or 2 can be individually programmed to output channels A , B, AB. When more than one internal channel is output from one of the BNC connectors, the channels are mixed with a logic AND operation.
