RX Section
AIP: OFF
1. Connect the signal generator to the ANT terminal at 14.2MHz
USB, apply a signal of 0dBµ (EMF), tune so that the AF output
beat frequency is 1kHz, and adjust the AF VR so that the AF
output is 0.63V/4Ω.
2. Connect the signal generator to each measurement point (cut
off the DC), and the AF output in step 1 so that the above EMFs
set are obtained.
During measurement, the beat frequency of the AF output is
normally 1kHz.

3. The signal type connector, TP, shown by
removing the coaxial cable inside the set, which is connected
to that connector, and connecting the signal generator in its
place. The station transmission system connector shown by
is a value measured by connecting the coaxial cable within the
set connected to that connector (input must be 50Ω) to the
spectrum analyzer.
4. The AF stage level is the level measured at AF V.M for each
stage during the conditions indicated in step1.
