Carrier to Interference Ratio (C/I)

Carrier to Interference Ratio (C/I) Measurement is a two-step process, first measuring the

carrier level and then, with the carrier turned off, measuring the remaining signals and noise

in the band of interest. After the two measurements are complete, the ratio of the carrier

level to the noise plus interference is displayed using three assumptions:

The interferer is a narrowband frequency hopping signal source (NB FHSS)

The interferer is a wideband frequency hopping signal source (WB FHSS)

The interferer is a broadband signal (BB)

The primary application for this type of measurement is determining the magnitude of inter-

ference problems for 802.11b, 802.11g and 802.11a access points (hot spots).

Procedure

Step 1.

If necessary, press the

MODE

key and use the Up/Down arrow key to select the

Spectrum Analyzer

mode. Press the

ENTER

key to select.

Step 2.

Press the

Signal Standard

soft key. Select the appropriate signal standard based

on the signal to be measured and press

ENTER

Step 3.

Press the

Select Channel

soft key, select the operating channel of the access

point being measured and press

ENTER
