Left/Right key to move the marker along with the trace)
Also we use Left/Right key during the selection of
freq. range & dist. Range.

USES
![Page 11: Industrail Trainining in Telecommunication](https://reader034.fdocuments.us/reader034/viewer/2022052310/549e6291ac795942768b46e4/html5/thumbnails/11.jpg)
It gives graphical representation of the measurement.
It can measure the VSWR with respect to frequency.(780
MHz – 2500 MHz)
It can measure the VSWR with respect to distance.(0 – 500
meter)
It can give multiple reading (up to 6) simultaneously.
It can store the measured traces up to 500.
New measured trace can be compared with the older one.
The traces can be imported or exported from the analyzer to
laptop.
It doesn’t require the BTS for the measurement of VSWR,
return loss, cable loss and insertion loss.

There are three different modes in Site
Analyzer as listed below:-
1. Measure Match Mode
2. Fault Location Mode
3. Measure Power Mode
Suppose site analyzer is initially in fault location
mode. So change the mode to measure match mode
to measure VSWR.

Here we have to change the Frequency Band because Antenna & BTS working on specific Frequency band.
Suppose they are working on GSM- 900 Band.So we have to change the frequency from 890 to 960 MHz.

Now we have to calibrate Site Analyzer by using Calibration Kit.In calibration process we set the Site Analyzer internal loss into Zero. It means VSWR of site analyzer goes to 1 at zero meter distance(at the port of site analyzer). We calibrate site analyzer by connecting Open, Short & Load port of calibration kit to RF Antenna port of SA one by one.

Here the it is shown that VSWR of the Antenna
line is 1.38 which is beyond the acceptable limit
i.e. 1.30.
So we have to rectify this fault. To rectify the
fault We have to change the mode of site analyzer
from measure match to fault location mode.
Now change the mode to fault location then
press auto scale button…..

Here the fault is at 31m distance. Here we didn’t
consider the VSWR value whatever it is. value is
not used to measure VSWR. The achieved value of
VSWR means in Measure match mode.
According to the graph fault is at 31m distance
which may be at Antenna port or O/D Jumper
cable.
Rectify the fault & measure the VSWR in Measure
match. If still the VSWR value is high again repeat
& rectify fault.
Repeat this action till VSWR goes below
1.30(means 1.30 in measure match mode).
