RF Explorer WSUB1G+SLIM spectrum analyser

The WSUB1G+SLIM is a model with a bandwidth of 50 kHz - 960 MHz and comes with dual band 144-430 MHz and UHF 400-900 MHz antennas. This makes the meter suitable for use in frequencies such as walkie-talkies, 433 MHz, and mobile phone networks. This meter has functions such as peak max/hold, normal/overwrite and averaging modes. Furthermore, due to the internal LNA amplifier and attenuator it is possible to manually select the LNA gain and attenuation.

These RF Explorer handheld spectrum analyzers are inexpensive but still have a surprising list of specifications. When designing, installing and troubleshooting wireless systems, it is often quite difficult to predict the propagation of radio waves. These low-cost analysis devices offer the possibility to determine the properties of of various frequencies. For an extensive overview of the possibilities an introduction video has been made. This video can be found at the bottom of this page.

These solid aluminum analyzers have a large 1800mA/h battery, so they can be used for more than 20 hours on a charge. With the included software they can display data on a PC, in high detail and with various functions such as '3d-waterfall' display, CSV and image export. In addition, the meter can be connected to a phone via an OTG cable, and can be measured via an Android app. This app can be downloaded and tried for free, but requires an optional license to work with the meter. Optionally there are several third party software packages available via this site. Users get lifetime firmware updates for free.

Via an internal upgrade connector, various extensions can be added to the analyser at a later stage.

The disadvantage of these mobile spectrum analysers compared to their tabletop alternatives can be found in 2 important differences. The noise floor and bandwidth are a lot better of the table models that can also be found in this category. Furthermore, these devices are for the price and size very good alternatives.
