AF 1kHz
Measurement condition (TX-RX 1 unit)
Frequency : 14.2MHz
PRE AMP : ON
ANT input : –113dBm/0.501µV
AF output : 0.63V/8Ω, 1kHz
Mode : USB
The values in parentheses ( ) are those in FM mode.
Input –113dBm from the antenna, set AF VR so that AF output is 0.63V, and measure
the signal level at each part.
The AF section is measured with an oscilloscope and the other parts are measered
with an RF voltmeter.
Measurement condition (TX-RX 2 unit)
Frequency : 144.0MHz (VHF), 438.2MHz (UHF)
PRE AMP : ON
ANT input : –113dBm/0.501µV
AF output : 0.63V/8Ω, 1kHz
Mode : USB (Main), FM (Sub)
Input –113dBm from CN1 and CN2, and measure the signal level at each part.
All wires, except CN1 and CN2, are connected during measurement.
The AF section is measured with an oscilloscope and the other parts are measered
with an RF voltmeter.
Measurement condition (TX-RX 3 unit)
Frequency : 1270.4MHz
ANT input :–113dBm/0.501µV
Mode : USB
Input –113dBm from the 1.2GHz antenna connector and measure the signal level at
each part.
Use an RF voltmeter.
