If the discontinuity is found, impulse response and step response graphs will not let
you know the exact reason of the problem, but will help in finding its location. You
could see how discontinuities of different nature affect impulse response and step
response graphs by experimenting with various cables, connectors and loads.
3.9. Calibration mode
Although RigExpert analyzers are designed to provide suitable precision without any
calibration, a simple “
open-short-load ” calibration method may be used to improve
the result. Moreover, this method may be used to remove the effects of a cable, so
accurate measurements at the far end of the cable become possible.
For this method, three calibration standards are required: an “
open
”, a “
short
” and
a “ load ” (usually, a 50-Ohm load). For better results, these standards should be of a
good quality. Additionally, physical length of all loads should be the same.
To perform OSL calibration just press Settings button, select OSL Calibration tab then
press Start button and follow on-screen instruction.
You can turn on and off OSL calibration any time just pressing Turn On/Off button in
Settings - OSL Calibration window.
