Determine
if
a
Calibration
is
Necessary
This section shows you how to determine if your measurement system
requires a user-dehned calibration.
When
a
Calibration
Is
Not
Necessary
l
Your test doesn’t require the best accuracy possible.
l
Your test device is connected directly to the reflection port with no adapters
or intervening cables.
l
Your test device impedance matches the impedance of the analyzer.
If your test setup meets these conditions, you do not need to perform any
additional calibrations, however without a user-calibration, the analyzer is not
guaranteed to meet its published measurement port speciiications.
When
a
Calibration
Is
Necessary
l
You want the best accuracy possible.
l
You are adapting to a different connector type or impedance.
l
You are connecting a cable between the test device and the analyzer test
ports.
l
You are measuring a narrowband or electrically long device.
l
You are connecting any attenuator or other such device on the input or
output of the test device.
