Operating Basics

Taking a Noise Floor Measurement

Noise

oor measures all the RF Power coming into the receive antenna within the frequency band of the selected channel. The

noise

oor is the power integrated across the selected channel. To make an accurate measurement, you must measure the noise

oor on a disabled channel (a channel that is not carrying live traf

c).

Connect a signal from a BTS receiver test
port to the instrument.

Set the instrument to display the spectrum
waveform of interest. (See page 31,

Displaying a Spectrum Waveform

Tap the

Reverse

(up) link button.

Tap the

Noise

tab.

Tap the trace of the interfering signal to
set the measurement frequency. You
can use the keypad or knob to adjust the
measurement frequency.
