The WSUB1G is a model with a bandwidth of 240 - 960 MHz and comes with a Nagoya NA-773 telescope antenna. This makes the meter suitable for use in frequencies such as walkie-talkies, 433 MHz, and mobile phone networks.
These handheld spectrum analysers from RF Explorer 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 inexpensive analysis devices offer the possibility to visualize the properties of various frequencies. For a comprehensive overview of the possibilities, a introduction video has been made.
These rugged aluminum analysers feature a large battery, making them more than 16 hours to use on one charge. With the supplied 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 telephone via an OTG cable and measured via a 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 through this site. Users receive lifelong firmware updates for free.
By means of 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 of this device are a lot better than the table top analysers that can be found in this category. Furthermore, these devices are very good alternatives in terms of price and format.
