Figure 11-3: Example of a calibration test setup
Input = [C1], [Gen1]
Output = [C2]
Consider also the following:
●
Calibration for FRA is only possible with probes connected to the input and output
channels.
●
For best FRA calibration results, shorten the DUT and place the probe tips as near
as possible to each other.
●
If there a fixture for the DUT it should be part of the calibration setup.
●
If the DUT needs a termination, it is to be conducted with an external termination
direct on DUT output / input.
Calibration state
Once the calibration is started, a label is shown in the toolbar.
The calibration label displays the status of the calibration. The following states are
available:
●
"Valid": calibration values are used
●
"Invalid": device settings changed
●
"Running": a calibration cycle is running
●
"None": not performed or no data
Settings influencing calibration
Calibration is only valid for the settings that are active during its execution. If one of the
following settings is changed, the calibration becomes "Invalid":
●
"Input" and "Output" channel
●
"Channel coupling" and "Bandwidth"
●
"Channel scaling"
