RF Explorer User Manual - updated

 

A fully revamped user manual for RF Explorer is available online.

 

We are making an effort to add complete documentation and keep the User Manual updated on every new firmware release or upcoming product model. The new user manual is also available from the RF Explorer for Windows help menu, and the link is using a global reference that comes automatically updated with any new version of the user manual.

 

 

RF Explorer for Windows - new version v1.11 available

 

This is a major update available with lot of new functionality, enhancements and fixes. The new version is available in the download area,

Among other things, it includes full compatibility with firmware v1.11, timestamp on screen and data files, Max Hold mode, remote selection of active RF module in the device, an improved Remote Screen dump, on-screen representation of the connected device, and a large etc. Please read the full list of features in the release notes document.

 

 

We want to thank all RF Explorer users who really help us to improve the software with useful feedback, but also by spreading the voice about this little device and being behind every order which is the foundation of all these enhanced features and many more that are coming.

Adapters and coaxial cables for RF Explorer available

As we get regular requests to get references for connectors and adapters that are 100% compatible, SeeedStudio and some distributors are now offering a set of accessories for RF Explorer. We looked for quality, reasonable priced adapters that will help you connect RF Explorer to pretty much any RF device or antenna you may need:

BNC adapter - Most HAM and two-way handheld radio antennas and devices are designed for BNC connectors. This BNC-female to SMA-male connector will easily interface your RF Explorer to any other BNC antenna or cable.


N adapter - Laboratory grade RF bench size instruments use N connector size cables. This N-female to SMA-male connector will easily interface your RF Explorer to any other bench size instrument or cable.


RP-SMA adapter -  Some WiFi antennas and cables are designed for RP-SMA (reverse polarity SMA) and cannot be connected to a standard SMA plug. RP-SMA is a variation of the SMA connector specification which reverses the gender of the interface. The reason for that was a decision made by FCC in order to prevent end-users from manipulating certified WiFi devices at home, using other available SMA antennas. That led to SMA and RP-SMA devices not being able to connect without an adapter, check Wikipedia for more details.

If you want to use some standard WiFi antennas you may need this adapter in order to interface them with RF Explorer. By plugin in this adapter your RF Explorer will be able to connect with any RP-SMA antenna, cable or device.


SMA right angle - This RF connector is ideal to use RF Explorer deployed horizontally, with any antenna connected onto it. For instance when you are on the road and you don't have a RF Explorer Stand, you can still easily fit the USB cable, the antenna and connect to a computer with easy. It is also useful to create a more reliable ground-effect for the antenna if fit the RF Explorer over a metallic structure such as a car roof.


SMA cable, 50cm long - Good up to 3GHz, these coaxial cables are good to connect your RF Explorer to other devices or antennas. There is a version with Male-Female connector (so you can actually cascade multiple ones if you need to) as well as Male-Male.

Introducing the multipurpose RF Explorer Power Limiter + DC block + 6dB attenuator

The RF Explorer Power Limiter is a custom, 3-in-1 device designed from the ground up to be the perfect protection against strong RF fields.

 

The RF Explorer Power Limiter is assembled in a rugged aluminum case and it is very compact when compared to other market offerings. Not only that, it also includes internal DC block and 6dB attenuator which makes it very versatile yet really small device for all it offers.

Why you would need a power limiter? As you can see on this note all RF Explorer models have input signal power ranges beyond which can be damaged. For most models (such as WSUB1G, ISM Combo or 2.4G), the limit is on +5dBm, some others are ok up to +10dBm (such as 433M-915M) but only WSUB3G (3G Combo right SMA connector) is protected up to +30dBm.

 


The new RF Explorer Power Limiter will allow any RF Explorer model to be protected with external signals up to +30dBm (1 Watt), so you get the same level of protection as in the WSUB3G. Furthermore, the power limiter includes additional functionality inside that will otherwise require external devices increasing cost and size, it is a true 3-in-1 device:


•   Power limiter:  protection up to +30dBm, for any frequency range between DC-3000Mhz
•   DC block:  You can connect any external source with DC voltage up to 16V with no risk of damaging your RF Explorer or interfering in your measurement.
•   Attenuator: Includes an internal 6dB attenuator to help you extend the range of power signal measurements. 6dB attenuation means a ¼ of the input power is received by the unit. To compensate for this extra attenuation you should indicate OffsetDB: +006 in the ATTENUATOR MENU of your RF Explorer.

The RF Explorer Power Limiter is available at SeeedStudio for $45 - that is about five times lower price you would have to pay for features like these in the general market. RF Explorer distributors will have it available soon, contact your local distributor for more details.

As we put significant effort an expense on this design, we will reuse this aluminum cage for additional accessories, including filters for popular R/C, FPV, ISM and HAM frequencies.
