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)
2. Connect the audio analyzer to the OUTPUT connector
via MIC amp.
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
FREQUENCY (carrier frequency) :
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
RF OUTPUT (Output level) : 60 dBuV
MODULATION (Modulation frequency) : 1 kHz
DEVIATION (Frequency deviation)
5. Read the output level of the OUTPUT connector (Audio
analyzer indication level).
This level is specified to be 0 dB.
6. Turn OFF the MODULATION (modulation frequency)
of the signal generator (No modulation).
7. Check that output level of the OUTPUT is 62 dB or
more (S/N is _62 dB or less with A-weighted filter) as
compared with the level of procedure 5 above.
8. Change the RF OUTPUT (output level) of the signal
generator as shown below.
RF OUTPUT (output level) : 15 dBuV
9. Check that output level of the OUTPUT is 36 dB or
more (S/N is _36 dB or less with A-weighted filter) as
compared with the level of procedure 5 above.
10. Change the RF OUTPUT (output level) of the signal
generator as shown below.
RF OUTPUT (output level) : 60 dBuV
11. Set the audio analyzer to the distortion mode.
12. Check that distortion ratio is _40 dB or less (1 % or
less) with A-weighted.
UWP Series
13. Connect the signal generator to the CN101/RF-130
board with the MM-SMA conversion connector and the
RF adjusting cable.
14. Perform the procedures 4 to 12 above.
15. Set the channel and FREQUENCY (carrier frequency)
of the signal generator as shown 1 and 2 below.
Perform the procedures 3 to 14 above, for each channel
setting (1 and 2).
