ADJUSTMENT
Adjustment Condition & Tuning
Adjust so that the transceiver power voltage
is stable with the voltage from the power
terminal at 7.5V during TX.
Use adjustment software to adjust the
adjustment output to the values below.
Adj. Freq. Greatest Low Band Freq.
Hi Power 5.0W
L2 Power 2.0W
L1 Power 1.0W
Check that the in-band TX output is within
the specifications below.
Hi Power 4.0~6.0W
L2 Power 1.2~2.8W
L1 Power 0.5~2.0W
Check that the in-band power consumption
is within the specifications below.
Hi Power Less than 2.0A
L2 Power Less than 1.5A
L1 Power Less than 1.2A
Connect a spectrum analyzer to the ANT
terminal through an attenuator. Set the
attenuation so that the spectrum analyzer
does not distort.
Set the transceiver to TX and when at Hi
power, check that spurious is less than the
value below in the bandwidth.
Spurious Less than –65dB of the
fundamental wave
