Making Measurements

Making an Average Power Measurement

external zeroing for input signals

below

30 dBm for

best accuracy.

Making a Basic Average Power Measurement

To make an average power measurement, connect the

power sensor and cable, zero and calibrate the meter,

before making a measurement.
Zeroing of the Power Meter will occur automatically:

• Every time the Power Meter function is used.

• When a 5 degree C. change in instrument

temperature occurs.

• Whenever the power sensor is changed.

• Every 24 hours (min.).

• Before measuring low level signals

for example,

dB above the lowest specified power

the

power

sensor

is capable of.

Calibrating the Power Meter every time you cycle the
power on

and off.

In most situations, you can press

{Zero}

to complete the

two steps (zero and cal) together.

NOTE

If you suspect other signals may be present, it is

recommended that you turn off all the other channels and

measure average power only on the signal of interest.

Another option is to measure channel power (which is less

accurate), that filters out all other channels (signals). You can

measure channel power for CDMA using the CDMA Analyzer

or CDMA Over Air tool. For other modulation formats, use

their respective analyzers (that is, GSM, 1xEV-DO, or

W-CDMA) or measure channel power using either the

spectrum analyzer or the Channel Scanner tool.

NOTE

Connect the power meter as close as possible to the power

amplifier/duplexer output. Do not use a coupled port. Sensors

may not be as accurate at the power levels provided by

coupled ports.
