Using Interference Analyzer

RSSI

The Received Signal Strength Indicator (RSSI) is a multi-signal tracking metric that is particularly
useful for measuring power-level variations over time. The RSSI measurement lets you assign power
limit line for audible alarms and increase alarm counters every time a signal exceeds a defined limit
line. For long-term analysis, the spectrogram and RSSI measurements can be automatically saved
into an external USB memory. Post-analysis can be performed with JDViewer application software.

Setting measure setup

Procedure

1.

Configure test parameters as described in the

“Configuring test parameters” on page 95.

2.

Press the

MEASURE SETUP

hot key.

3.

To set up the alarm parameters, complete the following steps:

a.

Press the

Alarm

soft key.

b.

Press the

Alarm at

soft key and select the marker number: M1 to M6 .

c.

Press the

Limit Line

soft key to set a threshold for the alarm.

d.

Enter a value by using the numeric keys. You can also use the rotary knob.

e.

Press the

dBm

soft key.

f.

Toggle the

Alarm

soft key between

On

and

Off

to turn the alarm feature on or off.

g.

Optional

. Press the

Volume

soft key and adjust the volume.

4.

To set up the AM/FM audio demodulation, complete the following steps:

a.

Press the

AM/FM Audio Demod

soft key.

b.

Toggle the

Audio Demod

soft key between

On

and

Off

to turn the AM/FM audio

demodulation on or off.

c.

Press the

Demod at

soft key, and then select the marker number for the frequency to be

demodulated.

NOTE

For the alarm and AM/FM audio demodulation, you must set the marker(s) first by using
the

MARKER

hard key as these features use the marker position to sound alarm or

demodulate. See

“Using marker” on page 54 for more information.

d.

Press the

Demod Mode

soft key, and then select the demodulation mode:

AM

,

FM

and

CW

.

e.

Press the

Dwell Time

soft key, and then turn the rotary knob to set the demodulation

interval between 1 and 20.

f.

Toggle the

Auto Gain

soft key between

On

and

Off

to enable or disable the automatic gain

feature to adjust the interval gain of the demodulator.

g.

Optional

. Press the

Volume

soft key and adjust the volume.

5.

To start a new measurement, press the

Reset/Restart

soft key.

6.

Optional

. Go to
