Transmitter Output Meter, type TF 912.
Covering the frequency range 80-160 Mc/s, it is battery-operated, self-contained, and portable.
The scale expansion of the meter is such that low-power transmitters can be checked at an open part of the scale.
The basic design feature is a bolometer bridge with a moving coil indicator employing a 75 ohm resistively terminated input line of novel character.
