Connections
(For connecting the DC power supply, refer to step
“3. Connecting the DC power supply” in Section 2-1-2.)
Procedure
1.
Input 1 kHz,
_
60 dBV (
_
57.8 dBm) signal to the AF
INPUT connector.
(0 dBV = 1 Vrms)
2.
Connect a modulation analyzer to the antenna terminal
(CN301/RF-131 board) via the MM-SMA conversion
connector and the SMA-BNC conversion connector.
3.
Adjust
1
RV521 so that the frequency deviation for the
modulation analyzer reading meets the following speci-
fication.
Specification :
Frequency deviation =
±
7 kHz
±
0.1 kHz
Adjustment :
