7.6.1 Calibration tab
Provides general system error correction (calibration) settings.
Auto Power Setting for Cal Unit
Sets the source power at all test ports to -10 dBm while an automatic calibration is
active. Applying this source power to the ports of the calibration unit ensures best
accuracy of the automatic calibration. The source powers are reset to their original val-
ues after the calibration is completed. The automatic power reduction can be deactiva-
ted in case that the test setup introduces a large attenuation.
Remote command:
SYSTem:COMMunicate:RDEVice:AKAL:PREDuction[:STATe]
Auto Averaging
Activates automatic averaging, which means that the VNA performs multiple calibration
sweeps and applies averaging to reduce trace noise. In contrast to regular averaging
(see Chapter 10.4.3, "Average tab", on page 323), the number of calibration sweeps is
calculated automatically.
Remote command:
[SENSe:]CORRection:COLLect:AVERage
Show Cal Kit Label
Enables/disables the "Calibration Info" dialog during manual calibration (see "Start Cal
Sweep" on page 486).
