F170 Frequency Generator 20 Mhz


20 Mhz square wave programmable frequency generator.


The new F170 square wave frequency generator is based on the same hardware as the F165. It has all the features of the F165 plus 3 additional internal channels for a total of 6 programmable channels. It can run standalone up to 1500 program files copied from a PC or Mac or created from the keypad. It is also possible to connect the F170 to a computer via a USB port and control it with the F100 software. Program files written for our current F165/125 models are compatible with the new F170.


F170 Specifications:

  • Standalone DDS square wave frequency generation controlled by internal 32 bit processor
  • 2MB internal flash memory to store up to 1500 individual frequency program files
  • Backlit LCD display (2 lines x 16 characters) and 16 key keypad to open/run files
  • MS-Windows and Mac OS X F100 3.0 software to copy files to the generator internal storage
  • MS-Windows F100 3.0 software to control the F170 from a PC USB port in the same way our current generators operate.
  • All software can be freely downloaded from our web site in the downloads section
  • Create/edit/run program files from the keypad, no PC necessary.
  • Program file format fully compatible with F100 2.0 and our previous/current generators
  • 6 internal channels that can run freqiencies from 0 HZ to: A:3.9 MHZ, B:3.9 MHZ, C:50 MHZ, D:50 MHZ, E: 50MHZ, F:3.9MHZ
  • 2 external BNC output connectors (I and II), BNC I is 5 V TTL, BNC II is variable amplitude.
  • BNC output I frequency range: 0 to 50 MHZ
  • BNC output II frequency range: 0 to 20 MHZ (50 MHZ with reduced amplitude)
  • Channels A,B,C,D,E,F can be routed to BNC outputs 1 or 2 in any combination (see note 2)
  • Any of the 6 internal channels can be used as a carrier for the other 5 channels
  • Channel A,B,F frequency resolution: .001 HZ
  • Channel C,D,E frequency resolution: less than .0009 HZ (see Notes 1 and 3)

  • 6ft USB cable included
  • 2.1 mm Input power connector
  • Wall transformer provided with North American plug type. Compatible with 110VAC-240VAC 50-60HZ input.
  • Power input: 2.1 mm, 12 VDC, 1A.
  • One year warranty , parts and labor.

Note 1: The step resolution on channels C,D,E depends on the programmed frequency. It varies from .0009 to .000056 HZ. (see Note 3)

Note 2: The F170 has 6 independent internal frequency generators (A,B,C,D,E,F) 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, C, AB, AC, BC, ABC, ABCDEF, etc . When more than one internal channel is output from one of the BNC connectors, the channels are mixed with a logic AND operation.

Note 3: One advantage of this new generator platform is that the internal channels are reconfigurable at the factory. This allows us to make modifications for customers who have special needs such as a finer resolution. If you have such needs, please contact us and we will be happy to quote you a price for a modified F170. Please indicate modifications required and quantity ordered.
