ASMxxxx Series User’s Manual
Asia Pacific | EMEA | Americas 161
Q – Can the ASM measure VHF 5KHz, 7.5KHz, 15KHz, 20KHz and 30KHz offset frequencies?
A – Yes. The ASM can measure, monitor and alarm any channel frequency step multiple of 1.25KHz.
Q – Can the ASM measure Tx-Rx Antenna Isolation, Rx Subsystem Gain/Ripple and Tx Carrier Rejection?
A – Yes. The ASM can measure, monitor and alarm these three System Tests for up to 20 frequencies.
Q – Can the ASM support SNMP alarm reporting and monitoring?
A – Yes. The ASM can report alarms via SNMP v2c northbound alarm traps, and can be polled by a southbound
GET command. The GET command will respond with the associated OID’s current parameter value.
Q – Can the ASM support Diversity Rx, Dual Rx Antennas, and Redundant Rx Antenna systems?
A – Yes. The Receive Systems Module (RSM) may be added to the ASM at any time to provide Rx signal path
monitoring for two receiver systems (i.e. dual diversity or redundant Rx antennas). The RSM also provides a third Rx
signal path that may be used for off-air monitoring of adjacent network sites’ coverage, a co-sited Distributed
Antenna System (DAS), or other signals that may be outside the Rx system(s) passbands. The RSM also improves
the ASM’s receiver sensitivity capability, facilitating the monitoring of lower level Rx signals.
