Chapter 3 — Calibrating the E7000L
Introduction
This chapter provides a guide to calibrating the E7000L SitePROFILER’s measurement apparatus. Calibration
of the E7000L to the Open, Short, and Load standards is important for achieving accurate, reliable results.
Measurement calibration should be performed after setting your measurement start and stop frequencies,
but prior to making a measurement.
Generally, it is best to calibrate the instrument after turning it on and allowing approximately 10 minutes for
warmup.
3-1 Calibration Equipment
3-1.1 — Manual and Automatic Calibration
The calibration procedure requires one of the following Open, Short, Load (OSL) calibration devices:
•
Mechanical “Y” OSL CAL device (manual calibration)
•
Electronic eCAL OSL device (automatic calibration)
Please select the device and method that best suit your measurement needs.
Manual Calibration
Using the mechanical “Y” OSL CAL device optimizes calibration accuracy and measurement results.
This method requires that you connect the “Y” OSL device to the SitePROFILER and follow a short series of
prompts as displayed on the E7000L SitePROFILER, as well as periodically rotating the “Y” calibration device
through the Open, Short, and Load positions.
Automatic Calibration
The electronic eCAL OSL device offers a quick, automatic solution to the calibration process. Measurement
results may suffer some accuracy loss compared to those recorded after a manual calibration.
This method requires that you connect the eCAL OSL device to the SitePROFILER in both the RF Out and USB
ports (using a USB-to-mini-USB cable) and press
Start CAL
(located in the instrument’s
Calibration
sub-menu).
The eCAL OSL device will automatically cycle through the Open, Short, and Load positions.
