CPUOSM calibration
A SMARTer UOSM scalar vector mixer calibration using a calibration unit, a power
meter and a calibration mixer.
Same procedure as described in "VPUOSM calibration" on page 1755; just replace
VPUosm by CPUosm.
8.2.6 Mixer measurement
The following example is a remote implementation of the tasks the Scalar Mixer Meas
setup dialog performs at the GUI.
A power meter and a four-port calibration unit has to be connected and configured
beforehand.
// Reset the analyzer
*RST
// Configure a linear frequency sweep
SENSe1:SWEEp:TYPE LINear // Sweep type
SENSe1:SWEEp:POINts 201 // Number of points
SENSe1:FREQuency:STARt 500 MHZ // Start frequency
SENSe1:FREQuency:STOP 2.5 GHZ // Stop frequency
SOURce1:POWer1 0 DBM // Base power
// Define the mixer
SENSe1:FREQuency:CONVersion:MIXer:STAGes 1 // Single mixer stage
