Operating Basics
The Edit Setting dialog allows you to perform the following tasks:
Con fi gure the channel plan by setting the following parameters:
Channel Number. Select which channel will be monitored from either
the ISDB-Tb or ISDB-T channel plans. Select the appropriate plan
and channel number for the input signal you intend to monitor.
Input Frequency. Enter the frequency for the selected channel. You
can set the channel frequency to any number between 170–862 MHz
in Hertz. If you set the input frequency to a custom value that does not
match the frequency of any of the channels in the selected Channel
Plan, the Channel Plan selected is set as None and Channel Number
list is made empty.
Ext Attenuator. Enter the dB value of any external attenuator that is
connected to the input signal. This allows the RFM220 system to
compensate for the attenuator and adjust the measurement thresholds
for reporting signal errors.
Left and Right Shoulder Distance. Enter the distance (in kHz) for
the left and right shoulders. This allows the RFM220 system to
compensate for the shoulder distance on the input signal. The default
value is 3150 kHz.
Con fi gure which signal will be output from the ASI output connector of
the RFM220 instrument. You can select either the ASI input signal or
the RF demodulated signal.
After you make any desired changes, click Apply to apply the changes. Click
OK to apply the changes and close the dialog box.
