Frequency Scanning – PCT GSM Scanner

1. After the scanner is connected and activated in Nemo Outdoor, open the

Measurement

Properties

dialog by selecting

Measurement | <device> | General Properties

2. By clicking the

Advanced

button, you will access the

Advanced Properties

dialog. Here

you can enable and disable the integrated GPS receiver. This means you will not need an

external GPS receiver in order to collect position data.

3. Go to the

Frequency scanning

page.

Channel style

refers to the style of the channel.

Selecting the

BSIC decoding

option displays BSIC value in a measurement window.

BSIC threshold

defines the minimum BSIC level that the scanner reports.

Select the

BCCH C/I

option to activate C/I measurements for the BCCH channel. This option is

available with PCTEL GSM scanners only.
