Handheld Cable/Antenna Analyzer
3-1.2 — Test Port Extension Cable
Although the SitePROFILER cable analyzer can connect directly to feedline and antenna equipment for
testing, in some cell site configurations this can be difficult or unsafe. For this reason, many sweep test
applications require the use of a test port extension cable.
NOTE: In the absence of a test port extension cable, a compatible cable with similar phase stability can
be used without negatively impacting measurement results.
When using a test port extension cable, please note that you must calibrate at the
end
of the cable prior to
making a measurement, or any time you disconnect and reconnect the cable.
3-2 Performing the Calibration
Once you have selected a calibration method according to Section 3-1, select a type of calibration to
perform. In general, it is recommended to choose Standard CAL if you plan on measuring only within a
given frequency range; choose Full Span if you plan on measuring within several different frequency ranges
and modes.
See the procedure for each type in the subsections below.
3-2.1 — Full Span Calibration
With the Full Span CAL mode, calibration is performed across the entire frequency range of the instrument.
Following a full span calibration, you may freely change measurement mode and frequency range without
the need to re-calibrate the instrument between operations.
Procedure:
1.
Tap the
Calibration
main menu key to open the Calibration submenu.
2.
Tap
Cal Method
to toggle between
OSL
(manual) and
E-CAL
(automatic); select the method that
corresponds to the calibration device in use. For more details, see Section 3-1.
3.
If you selected
OSL
in step 2, toggle
Cal Type
to
Full.
4.
Tap
Start Cal
to begin calibration. Follow the on-screen prompts.
Following a successful full span calibration, “FullSpan Cal ON” will appear in the calibration status tab on
the left edge of the display. You may now proceed with measurement operations as needed.
When the instrument is shut down or the test cable is removed, the full span calibration will no longer be
valid. “CAL OFF” will appear in the calibration status tab.
