Scanning should be done for both Uplink and downlink

frequency. Also make sure the scanning bandwidth falls

under our F1 and F2 band.

Below is setting in case above mentioned frequency(our

current scenario)

DL UARFCN:10675

UL UARFCN: 9725

Scanning bandwidth(span): 20MHZ

Note: above UARFCN is the middle UARFCN for our existing

F1 and F2.

Steps for Frequency scanning

Note: please charge the device completely before moving to

site.

1. Connect Charger(use DC charger cable to charge in car), antenna properly

Antenna connection port Power connection


3/18

Havent shown use of extension cable, to extend antenna out of vehicle plz use

enxtension cable.

2 . Power on the device

Power button

2.Open YBT 250 software


5/18

3.Set the values for scanning

a. Select WCDMA_1 2100b. Select DLc. Set channel to 10675d. Set Span to 20Mhz

Note: tools will show two graph i.e 1. Spectrum and spectrogram need both graph both for UL and

DL. UL steps is illustrated later.

For UL, U can directly click uplink button as shown but remember the DL UARFCN(channel) should beas per given, when you switch to UL using the button the UL UARFCN should change automatically to

given value. Below is shown

4.Save the graph-pause the scanning

-go to file

-click export screen as

It will automatically changeUL button

9/18

-Make new folder as of your name to save all graph in same place

Then go inside the folder and save the file with below format name

File name: Point1-DL-YYYYMMDD-HHMM-1/2

Descriptin: Point1 is name of the point given, DL means Downlink scanning( for uplink

will be UL), YYYMMMDD:year,month,date, HHMM: hour and minute,1-spectrum

graph/2-spectrogram graph.

Similarly follow for UL and DL for both Spectrum and Spectrogram graph.

2. This icon will help to get the

keyboard on screen

1. New

folder

3. filename

4. OK

Extracting saved data to USB drive

Connect usb drive to usb port


12/18

After connecting USB go to My Nettek


13/18

You will see two drives: Builtindisk and hard disk as shown below

Builtindisk: its internal disk of spectrum analyzer, is place where you will save

your graph in previous step of saving.

Hard disk: its USB drive and will only appear when we insert usb drive. Note

it will take some time to appear it after it will be inserted , wait 1 minuteabout.


14/18

Now select and copy files from where you have save


15/18

Now go to USB drive(display as hard disk) and paste files

Output needed :

Each Point scanning test Need 4 picture

1. DL Spectrum2. DL Spectrograph3. UL Spectrum4. UL spectrograph5. Excel containing Point name, Longitude, Latitude (exact long/lat should be

mentioned and the test point should be on 20 radius from provided Long/Lat)

Naming rule:

File name: Point1-DL-YYYYMMDD-HHMM-1/2

Descriptin: Point1 is name of the point given, DL means Downlink scanning( for uplink

will be UL), YYYMMMDD:year,month,date, HHMM: hour and minute,1-spectrum

graph/2-spectrogram graph.
