3 GHz Replacement Kit - PMO-030

3 GHz Replacement Kit - PMO-030

The PMO-030 is a replacement kit for the Input C option of the PM6680, PM6681 and PM6685 frequency counters, which have been discontinued. It allows you to measure signals from 100 MHz to 3 GHz.



  • 0.1 to 3 GHz bandwidth.  
  • High sensitivity.  
  • Does not self-oscillate.
  • Fully tested to ensure reliable measurements.    
  • 30 days, no questions asked, extended return policy.    

Package contents:

  1. PMO-030 board.   
  2. (optional) N-type connector with cable. 

Warranty: 2 years.



This prescaler requires an N-type to SMA cable, 20 to 30 cm long. We used to offer a low cost variant, but because of the high batch-to-batch variation in quality, that is no longer the case.

The current cable options have tighter tollerances for higher quality mating and better repeatability. On the N-type side they feature a BeCu center contact, which should increase the average life span of the connector considerably.
