Chapter 1 Introduction
Designed for 50 ohm coaxial transmission lines, the Bird Antenna &
Cable Monitor is the solution for monitoring transmission antenna
systems. Service providers and end users can rely on it to keep their
critical sites up and running. Designed to detect antenna and cable
faults that transmitter-internal VSWR monitors may not detect, it
also provides accurate in-line power measurement functionality.
Features
z Measures forward and reflected power as well as VSWR and
Return Loss.
z Measures true average power of pulses with high peak-to-
average ratios - works with any modulation!
z Worldwide systems include Tetra, Cellular, and PCS with dig-
ital or analog modulation. Other applications include 3G,
AMPS, Broadcast, CDMA, CDMA 2000, DCS, EDGE, Govern-
ment, GPRS, GSM, iDEN, Industrial, NPSPAC, Microwave,
Military, Paging, Public Safety, Rail, SMR, TDMA, Tetrapol,
Trunking, UHF, Utilities, VHF, W-CDMA, and WLL
z When monitoring transmitter output power, alarms available
for low or high power.
z Accurately monitors antenna and cable system VSWR. Alarm
triggered if antenna or cable fails.
z Integral coupler measures small changes in VSWR through
high feeder and interface losses. High directivity maximizes
measurement accuracy.
z Sampling ports allow signal measurements without requiring
system downtime.
z Excellent passive intermod allows the unit to be inserted into
multichannel systems with a single Tx/Rx antenna with no
desensing or degradation of receiver performance.
z Can be rack mounted at the output of transmitter combiner or
linear power amplifier.
z Local or remote setup and operation via RS-232 port and
PCTool software. (For other telemetry options, such as TCP/
IP, contact the factory)
