MDS 05-6399A01, Rev. D MDS Master Station 59
5.6.5.1.10 SpectrumAnalyzer
A unique feature of the transceiver is the ability to view the RF spectrum above and below the operating
frequency using its built-in Spectrum Graph. Often, this can assist in diagnosing the cause of interference,
or to view other signals near your operating frequency. To use the Spectrum Graph, you must first
specify a center frequency and a scan width. The center frequency is the frequency that you wish the
spectrum display to be centered on. The span frequency defines the width of the overall spectrum to be
examined.
Once the correct values have been entered, switch it on using the on/off switch. The graph will
automatically refresh itself every 5 seconds. To stop scanning, turn the on/off switch off.
5.6.5.1.11 ForceAlarm
From the Force Alarm menu, you can force the SD radio interface cards to enter a test alarm state. To
activate an alarm, select which radio slot to alarm, and click the Perform action button. An “Alarm Test”
entry will be created in the Event Log, and the external alarm output status is changed. This can be useful
when testing event logging and propagation across a network, or when testing equipment connected to the
alarm output contacts on the Master Station. When enabled, the alarm will assert for 30 seconds, and then
deactivate. If active, it can be manually deactivated prior to timeout by deselecting the slot number of the
radio and clicking the Perform action button again.
5.6.5.1.12 RemoteSDFirmware
OTA Reprogramming Overview
NOTE: This feature is for reprogramming SDx remote radios only. This will not reprogram other Master
Stations on the network.
The “Root” is the central location from which polling originates. Other locations in the network should be
designated as “Nodes” which are the receiving stations. Over-the-air firmware upgrades should always be
initiated from the Root. This ensures that all radios in the network will be properly updated
