Abstract
PURPOSE: To make it possible to grasp how much tolerance to a power voltage an amplifier operates with.
CONSTITUTION: Output signal voltage (e) (rectified voltage) of the amplifier is applied to input terminal 1, and power voltage VB of the same amplifier to input terminal 2. Divider circuit 3 divides output signal voltage (e) by power voltage VB and its output is supplied to contact 4a of change-over switch 4. By changing over its contacts, change-over switch 4 selects either one of the output of the divider circuit, namely, the ratio of output signal voltage (e) to power voltage VB and output signal voltage (e) and then supplies it to meter 6 via meter driver circuit 5. According to the set state of change-over switch 4, meter 6 displays either the above- mentioned ratio (%) or level (dBm) of output signal voltage (e).
