(1) Output Level Check
1. Set the URX-P2 as follows :
Channel setting :
U30 model ;Group 03, 3201 channel (578.125 MHz)
U42 model ;Group 03, 4401 channel (650.125 MHz)
CE62 model ;Group 04, 6332 channel (810.000 MHz)
CE67 model ;Group 04, 6832 channel (850.000 MHz)
KR model
;Group 12, 6001 channel (746.125 MHz)
RF Squelch : OFF (For setting, refer to “Setting the
Squelch OFF mode” on page 2-42)
Monitor level: MON.01 (minimum value)
2. Connect an audio analyzer to the OUTPUT connector
via the MIC amplifier (with the 0 dB gain setting).
3. Connect the signal generator to the CN201/RF-130
board with the MM-SMA conversion connector and
the RF adjusting cable.
4. Set the signal generator as follows :
Signal generator setting
U30 model ; 578.125 MHz
U42 model ; 650.125 MHz
CE62 model ; 810.000 MHz
CE67 model ; 850.000 MHz
KR model ; 746.125 MHz
