Measurements

Average power is the most important measurement of any transmission system

since the average power is normally specified on the operating license. It is also

valuable as a maintenance tool, showing overall system health, and for

calibration.

Figure 32 Average and Peak Envelope Power - Square Wave Signal

VSWR

All Sensors

VSWR measures the relation between forward and reflected average power. The

Bird Wideband Power Sensor calculates the VSWR from the Forward and

Reflected Average Power measurements. Rho and Return Loss are also the same

measurement, but in different units:

Rho

VSWR

Return Loss (dB)

The health of the feedline and antenna systems can be monitored using VSWR

measurement under full power operating conditions. High VSWR is an indicator

of feed line damage, overtightened cable or feed line clamps, or antenna

changes/damage due to weather conditions, icing, or structural damage to the

tower.
