Fill User Correction Data with Sensor
●
"Sensor"
Displays connected sensors for selection.
●
"List To Fill"
Indicates the used list.
●
"S-Parameter"
Indicates whether S-Parameter correction in the R&S NRP power sensor is used.
●
"Include Zeroing"
Performs a zeroing procedure before acquiring the user correction data to improve
precision.
No signal is applied to the sensor during zeroing. RF output is temporarily switched
off during that time.
When unchecked, the zeroing procedure is skipped. However, the RF signal level
can be blanked shortly. This setting is useful if blanking of RF is undesirable or the
absence of power at the sensor cannot be guaranteed.
●
"Execute"
The "Execute" button is only enabled if a sensor is detected and the user correction list
contains at least one frequency value.
