The Rohde & Schwarz CTH100A/CTH200A handheld analog testers are versatile tools for the verification of analog FM radios. Designed for outdoor usage and rough treatment, the models ensure reliable maintenance and verification of FM radios in the field.

These units are simple to use - simply connect the radio and start the receiver and transmitter measurements. Power measurements and frequency counts provide information of the radio’s transmitter and the antenna, while a sub-audio squelch tone is generated as well as an audio tone to verify the radio receiver.

High accuracy and repeatability of the measurements ensure high-quality service and maintenance of all kinds of analog FM radios.

The instrument is ruggedised and performs according to the MIL-STD 28800F. A backlit display informs about selected measurements, results and device status. The backlight can be adjusted in several steps for convenient operation and measurement reading.

With a weight of around 500 g and its small dimensions, it fits easily into pockets and backpacks, which is important for those involved with in-field service and verification.
