Using Channel Numbers to Set Analyzer and Generator Frequencies
Using Channel Numbers to Set Analyzer and Generator
Frequencies
RF analyzer and RF generator frequencies can be entered by channel
number (the default setting) or by discrete frequencies (in MHz). The
RF Display field on the INSTRUMENT CONFIGURE screen controls
which way frequencies are entered. This screen is accessed by pressing
the
Inst Config key.
If the RF Display field is set to Chan
for channel tuning, you also need
to set the RF Chan Std field to LS AMPS to tell the Test Set you are
testing Land (base) Station AMPS radios. This automatically sets the
correct 45 MHz frequency offset needed to generate reverse channel
signals and analyze forward channel signals for an AMPS base station.
If you do not know the channel number of your base station, but know
the transmit and receive frequencies, set the RF Display field to Freq
.
You can then enter these frequencies directly for the RF generator and
RF analyzer during tests.
