The R&S®CTH allows dependable testing of analog FM radio systems even under challenging environmental conditions. The radio test set was designed especially for outdoor use.

The R&S®CTH100A/R&S®CTH200A simultaneously measures the forward and reflected power along with the frequency and presents the results on the display. The measured values are updated continuously so that any changes that occur will be displayed immediately. In this manner, it is possible to determine whether the transceiver’s transmit module outputs the desired power. Using this measurement, the R&S®CTH100A/R&S®CTH200A can reliably detect any decrease in transmit power or a transmitter failure. Plus, the R&S®CTH200A can determine and display the VSWR from the forward and reflected power. The reflected power measurement allows the antenna matching to be determined for insight into the power that is actually radiated by the antenna.
