You may also read the default path (MMEMory:CDIRectory?) and use the external RC program to build
the complete paths.
Noise Figure Measurement
The following example shows how to calibrate and perform a noise figure measurement.
// Reset the analyzer
*RST
:SYSTEM:DISPLAY:UPDATE ON
// Reduce number of sweep points for slow measurement
:SENSe1:SWEep:POINts 11
// Configure measurement (dialog "Define Noise Figure Measurement")
:SENSe1:SWEep:DETector:TIME 40 ms
:SENSe1:NFIGure:SEQuential OFF // simultaneous
:SENSe1:NFIGure:ISNoise OFF // Do not assume Ideal T0 Source Noise
:SENSe1:NFIGure:RFICorr OFF // Do not apply RF image correction
:SENSe1:NFIGure:NDUT OFF // Assume normal (no narrowband) DUT
// Configure meas. and noise figure calibration (dialog "Noise Figure Calibration")
:SENSe1:BANDwidth:RESolution 5 MHz
:SENSe1:BANDwidth:RESolution:SELect HIGH
