Please note that you need to order the top cover SKU 114991543 for correct assembly of the new expansion board. This is a separated accessory.


  • Compatible with RF Explorer RFE6GEN Signal Generator to be converted into an RF Explorer Signal Generator Combo
  • RF Explorer for Windows free software for CW, Sweep and Tracking SNA control
  • Automation libraries available in Python and .NET, free USB API for any programming language
  • Wideband support, very stable CW signal output
  • Fine amplitude adjustment 0.25dB
  • High output power up to +18dBm
  • Optional recalibration procedure available upon request 


RF Explorer Signal Generator Expansion adds major improvement to the standard RF Explorer RFE6GEN Generator. The new generator expansion board includes important functions requested by our most demanding customers. By adding this expansion board the RFE6GEN becomes an RF Explorer Signal Generator COMBO.
The new Expansion product extends the RFE6GEN to include harmonic filtering, high-performance amplifiers for higher output power, fine amplitude adjustment and support for frequencies as low as 100KHz covering up to 6GHz with no gaps.

See below comparison of a 25MHz signal generated with new improved RF Explorer Signal Generator Expansion (in red) and a signal generated with standard unfiltered RF Explorer RFE6GEN (blue). The new Generator Combo offers a perfect sinusoid filtered signal as opposed to the squarish unfiltered signal from RFE6GEN.

  1. Product Quality
    Easy upgrade nice capabilities
    I really appreciate the amplitude range which is much bigger and in 5 dB steps plus the upper end is up to about 15 dBm. Also the harmonic filtering is much more befitting of a signal generator. The upgrade took 15 mins to fit and needs a new top panel.
