Procedure
1.
Set the spectrum analyzer as below:
CENTER FREQUENCY :
U30 model
: 578.125 MHz
U42 model
: 650.125 MHz
U6264 model : 770.125 MHz
U6668 model : 794.125 MHz
CE62 model
: 810.000 MHz
CE67 model
: 850.000 MHz
REFERENCE LEVEL
: 20 dBm
FREQUENCY SPAN
: 500kHz (50 kHz/DIV)
RBW (resolution band width) : 1 kHz
VBW (video band width)
: 1 kHz
ATT
: 20 dB
2.
Set the carrier frequency level (the center frequency lev-
el of the spectrum analyzer) to the REFERENCE LEV-
EL when no signals are input.
3.
Input 1 kHz,
_
36 dBV (
_
33.8 dBm) signal to the AF
INPUT connector (with Mic input cable) from the audio
analyzer (oscillator).
4.
At this time, confirm that the bandwidth at the level
_
23 dB lower than REFERENCE LEVEL is in
specification.
Specification :
bandwidth =100 kHz or less
v:10 dB/div
H:50 kHz/div
_
23 dB
fc
