New RF Explorer for Windows v1.12.1503.3 available

Free download from

Includes all these enhancement and fixes:

  • Dark mode for Signal Generator
  • Save screenshot available in Signal Generator
  • Normalization data can be saved and restored for easy reuse of multiple measurement cases, with no need to re-normalize every time. Note: it is not suggested to reuse normalization files when the environment (such as temperature, cables, etc) changes too much when compared to initial normalization setup.
  • Signal Generator tracking results can be saved as CSV and standard S1P files. Note: files are considered S1P because only one parameter can be saved at a time, regardless if it is S11 or S21. If it is a 2-port S21 measurement, rename the file manually. Future enhancements will allow combination of multiple readings, such as S11 and S21 to be displayed together and saved to a S2P file.
  • Smooth trace enabled for Signal Generator
  • Print and Print Preview features working for Signal Generator
  • User can select "Insertion Loss" or "Return Loss" graphical Y axis label for Signal Generator trace. This will be expanded later to "Linear VSWR" and correctly calculated for easy VSWR display. In the meantime, traces can be exported to CSV and converted in Excel from dB into VSWR.
  • Corrected measurement data point on Signal Generator screen to be dB (as opposed to incorrect dBm reading earlier version)
  • Corrected Spectrum Analyzer trace color mismatch in MaxHold and Min.

RF Explorer firmware upgrade for 6G models

A new enhanced firmware is available for RF Explorer 6G and 6G Combo models.

This new version v1.12 Beta 12 includes 300MHz span for RF Explorer 6G, and 600MHz span for RF Explorer 6G Combo and WiFi Combo.

You can download the new firmware from the download page here. Please make sure you download and upgrade your unit with the right firmware file only!

For any question contact us.

We uploaded a brief demo of RF Explorer 6G Combo working at 5.5GHz with up to 600MHz span.

RF Explorer 6GHZ - update

We are happy to confirm the production and QC tests are being completed as expected for new 6G and 6G Combo units. Thanks for your patience and support, these last weeks we have been working on plenty of details to finish, so everything can be ready on time. Reminder: If you were considering a 6GHz unit, discount period ends tomorrow Jan 20th.


SeeedStudio team confirmed they will start shipping first units tomorrow Jan 20th, as initially planned. All the units pre-ordered will be shipped between Jan 20 and 24. 

For any question on your order, please check with directly with SeeedStudio , or the distributor you ordered the unit from. We do not handle individual orders ourselves.


Note: Firmware delivered with new unit shipped is version 1.12 Beta 08. Some features under development will required you to upgrade your unit with new firmware in a few weeks.



RF Explorer 6GHZ


RF Explorer with support up to 6.1GHz, in two different models, is now available for pre-order.

  • RF Explorer 6G: This is a standard main unit, one-port RF Explorer with 4850-6100MHz (4.85-6.1GHz) support, covering the most demanding 5.8GHz with excellent sensitivity. This model accepts an Expansion Module of your choice (such as RFEMWSUB3G or RFEM24G) for extra frequency coverage.
  • RF Explorer 6G Combo: This is the same as a RF Explorer 6G RFEMWSUB3G, being a two port RF Explorer with 15-2700MHz 4850-6100MHz coverage. This is the most advanced RF Explorer yet.

You can get more details on specifications at Models Map page


In order to help upgrade units from older models into 6GHz, we are offering a $35 discount till January 20th. Please visit this Q&A page here specific for 6G models that can help you decide which model is best for you, and how to efficiently upgrade a unit you already have (such as 3G Combo) into a 6GHz capable unit.


Pre-order period starts today at SeeedStudio and other distributors. Please check the distributor more convenient to you for details on expected shipping date. We will keep updating this news page with every update in the production process.

New product available: 6GHz attenuators


These high quality, 2 Watt attenuators have guaranteed linear response up to 6GHz (and are usable up to 9GHz with minimal linearity loss). We offer 30dB and 10dB attenuator at SeeedStudio and other distributors.

SMA attenuators are used to reduce the input power, and therefore enable RF Explorer to measure stronger signals. It is also used to protect the input SMA port of RF Explorer when unknown strong signals may be in the environment, so you can use this attenuator on demand. You can easily unplug the attenuator when measurement is for weak signals.

You can also daisy chain multiple attenuators to get additional values. For instance a 10 dB + 30dB attenuators connected in series will give you 40dB total attenuation.  

RF Explorer firmware includes an “Offset DB” feature in the Attenuator Menu, you should specify (+030) dB in this setting when the attenuator is connected in order to get correct readings on screen.
