Frequency:
The center frequency for the channel. The frequency must be a multiple of 0.00125 MHz.
Channel frequency steps of 5KHz, 6.25KHz, 7.5KHz, 10KHz, 12.5KHz, 15KHz, 20KHz, 25KHz and 30KHz are supported.
Modulation:
Selects the modulation type to be measured.
Note:
The channel measurement bandwidth is also selected in this field. Some modulation selections default the channel
measurement bandwidth (i.e. “TETRA” defaults to a 25KHz setting), but if multiple selections are available, then this
is easily identified by the modulation label (i.e. “FM12.5” is 12.5KHz, and “FM25” is 25KHz).
Threshold Pwr:
The minimum forward power level for which channel measurements and alarm status will be updated. If the detected power
level is below this value the signal will be considered as not present.
Add Row:
When the configuration page is loaded, only configured channels are displayed. To configure a new channel, click the Add Row
button to display the next available un-configured channel. Up to 20 channels may be configured for each Tx port.
Remove Selected Rows:
Clicking this button will return the selected rows to their default settings and remove them from the display. Rows are selected
by clicking the checkbox at the left of the row. Clicking the checkbox in the title bar will select all the rows. Note that the first row
is always displayed.
Note:
For any text field, the allowable limits for that field (Model dependent) are displayed when the cursor is hovered over it.
Defaults:
Clicking this button reduces the display to only the first channel and enters the factory default values for the Channel
configuration settings. To only restore specific channels to defaults, select them, and then use the
Remove Selected Rows
button followed by the Add Row
button. The default settings are;
Channel ID
"Not Defined"
ON
Not selected
Frequency
OFF
BW
25 kHz
Threshold Pwr
-120 dBm
Discard Changes:
Click this button to restore the values to those current saved. Note that if invalid values are being displayed after an Apply
attempt, these values may not match the current system configuration. In this case, just select the Configure/User Data menu
item again to re-display the current configuration.
Apply:
This will attempt to save and activate the values entered. If any out of range values are present, nothing will be saved and the
problem settings will be highlighted with a red background.
Note:
Whenever programming changes are applied, the alarm status for affected channels is re-initialized.
