Calibrate Transmission
Starts a transmission type measurement to determine a reference trace. This trace is
used to calculate the difference for the normalized values.
Remote command:
[SENSe:]CORRection:METHod
on page 794
Calibrate Reflection Short
Starts a short-circuit reflection type measurement to determine a reference trace for
calibration.
If both calibrations (open circuit, short circuit) are carried out, the calibration trace is
calculated by averaging the two measurements. The order of the two calibration mea-
surements is irrelevant.
Remote command:
[SENSe:]CORRection:METHod
on page 794
Selects the reflection method.
[SENSe:]CORRection:COLLect[:ACQuire]
on page 793
Starts the sweep for short-circuit calibration.
Calibrate Reflection Open
Starts an open-circuit reflection type measurement to determine a reference trace for
calibration.
If both reflection-type calibrations (open circuit, short circuit) are carried out, the refer-
ence trace is calculated by averaging the two measurements. The order of the two cali-
bration measurements is irrelevant.
Remote command:
[SENSe:]CORRection:METHod
on page 794
Selects the reflection method.
[SENSe:]CORRection:COLLect[:ACQuire]
on page 793
Starts the sweep for open-circuit calibration.
Normalization state
Switches the normalization of measurement results on or off. This function is only
available if the memory contains a reference trace, that is, after a calibration has been
performed.
Remote command:
[SENSe:]CORRection[:STATe]
on page 793
Reference Position
Defines the position of the reference line in percent of the total y-axis range.
The top of the diagram is 100%, the bottom is 0%. By default, the 0 dB line is displayed
at 90% of the diagram height.
This setting is only available if normalization is on (see " Normalization state"
on page 296).
The reference line defined by the reference value and reference position is similar to
the
Reference Level defined in the "Amplitude" settings. However, this reference line
only affects the y-axis scaling in the diagram, it has no effect on the expected input
power level or the hardware settings.
