New PLUS SLIM models

ISM Combo PLUS hand small

The new robust and ergonomic SLIM enclosure you can see in these images is the foundation for all new RF Explorer models. This new enclosure is strong, fully metallic with a special design to expose the USB connector conveniently on the side, easy to operate and eye catching. Internally fits a larger battery of 1800mAh almost double capacity than standard models.

With the upgraded ISM COMBO+ and WSUB1G+ models you can get additional capabilities in upcoming firmware releases; most of the upcoming features will not be suitable for baseline ISM Combo and WSUB1G.


For additional details please visit ISM Combo+ Specs and WSUB1G+ Specs

SeeedStudio is offering free shipping in these products, order online links below:


RF Explorer expansion RFEM2.4G+

The new expansion board is the same used by the RF Explorer ISM COMBO+ and can be used to enhance a WSUB1G PLUS model to become a ISM COMBO+. This board is suitable for new and old device design, so any user with a WSUB1G+ model can upgrade to get coverage on the 2.4GHz band.

The RFEM2.4G+ include advanced features when compared to standard RFEM2.4G module, including higher RF output power in generator mode, and higher sensitivity.

Note this can only be assembled in WSUB1G PLUS model (9 keys keyboard), not in standard models with 7 keys keyboard (such as WSUB1G).

Introducing new RF Explorer Signal Generator Combo

We are happy to introduce the new enhanced version of the RF Explorer Signal Generator.

The new model includes an internal expansion board to enable three major requests from advanced customers:

  • Frequency range now starts at 100KHz and covers up to 6GHz, compared to the baseline generator starts at 23.4MHz.
  • Output power range is no longer limited to 8 discrete levels, it can provide calibrated output with 0.25dB steps in range of -40 to +10dBm. Uncalibrated power output can go from -60 to +15dBm (a future firmware upgrade will allow up to +18dBm in certain frequencies)
  • Output signal is now strongly filtered for harmonics wideband. See a comparative example below at 25MHz as a good reference of the new harmonic filter in action in the time domain, measured with an oscilloscope.

The same improvement in the frequency domain shows the original signal output from the baseline RF Explorer Signal Generator and the output from the new Combo model.

This new and improved functionality can be added to any existing RF Explorer Signal Generator by simply plugin a RF Explorer Signal Generator Expansion board on it. A challenging design which took over 2 years of multiple refinements to find the best approach to deliver this wideband filtering capabilities at this cost and size.

For additional details:

  • RF Explorer Signal Generator Combo - specifications and datasheet
  • RF Explorer Signal Generator user manual - it includes new detailed sections for fine amplitude control, harmonic filtering and enhanced capabilities

Additional options for ordering from local distributors will be available in the next few days.
