F125 Frequency Generator 1.5 Mhz


1.5 Mhz square wave programmable frequency generator.

Out of stock


The F125 square wave frequency generator replaces our F150/155/105 frequency generators. It is a completely new design with many new features. The main one being that it 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 4.x software for MS-Windows in the same way our F150/155/105 operate from a PC. Program files written for our current F150/155/105 are compatible with the F125.

F125 Technical Specifications

  • Standalone DDS square wave frequency generation controlled by internal 32 bit processor
  • 2MB internal flash memory to store up to 1800 individual frequency program files
  • Backlit LCD display (2 lines x 16 characters) and 16 key keypad to open/run files

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.
