F104 Frequency Generator board


2.5 Mhz square wave programmable frequency generator.


The F104 square wave frequency generator is a USB and WiFi connected, dual channel , 2.5 MHZ square wave generator. It can be driven from a PC , Mac or Linux computer. It can also run one program file in standalone mode, not connected to a computer. The F104 needs a USB or wireless Wifi connection to a computer  to be programmed using the F100 7.x software. Program files written for our F125/165/170/101/102 are compatible with the new F104. The F104 has a single 5V TTL BNC output.
