If no unit is specified, the system default unit dB is used.
Return value:
Y factor
Example:
:FETCH:UNCorrected:YFACtor? DB
[ Cold Power Measurement - Uncorrected ]
:FETCH:UNCorrected:PCOLd?
Function description:
This command is used to query the uncalibrated cold power value within the
range of the sweep frequency.
Query format:
:FETCH:UNCorrected:PCOLd? DB|LINear
Parameter description:
The unit is DB or LINear.
If no unit is specified, the system default unit dB is used.
Return value:
Cold power value
Example:
:FETCH:UNC:PCOLd? DB
Description:
The noise figure analyzer can measure cold power when the noise source is off,
and the power is related to
the power of the instrument port.
[ Hot Power Measurement - Uncorrected ]
:FETCH:UNCorrected:PHOT?
Function description:
This command is used to query the uncalibrated hot power value within the
range of the sweep frequency.
Query format:
:FETCH:UNCorrected:PHOT? DB|LINear
Parameter description:
The unit is DB or LINear.
If no unit is specified, the system default unit dB is used.
Return value:
Hot power value
Example:
:FETCH:UNC:PHOT? DB
Description:
The noise figure analyzer can measure hot power when the noise source is on, and the
power is related to the power of the instrument port.
[ Equivalent Noise Temperature Measurement - Uncorrected ]
:FETCH:UNCorrected:TEFFective?
Function description:
This command is used to query the uncalibrated equivalent noise temperature
within the range of the sweep frequency.
Query format:
:FETCH:UNCorrected:TEFFective? K|CEL|FAR
Parameter description:
The unit is K|CEL|FAR, or K, C, F.
If no unit is specified, the system default unit K is used.
Return value:
Equivalent noise temperature
Example:
:FETCH:UNC:TEFF? K
