Abstract
PURPOSE: To enable to read the most suitable input level of a radio unit, by detecting the level of the output signal of the attenuator adjusting the reception input with a plurality of IF amplifiers and displaying the level with a meter.
CONSTITUTION: The level of the input signal to a receiver is adjusted with the attenuator 2 and the output is introduced to the IF amplifiers A6 and B7 via the mixer 5, and output is made from the detection circuit 8 via the low frequency circuit 9. Carrier is detected between the IF amplifiers 6 and 7 and the meter 12 obtains an indication by it.
