Example 3
– Create an S-Parameter table
– Assign S-Parameter data in the magnitude-phase format for a frequency value
– Select S-Parameter as the DUT Gamma
– Turn on the RTMU feature
->
SENS:CORR:CSET3:STAT OFF // Turns off Table-Based Gamma
Correction in order to include the
mismatch between the DUT and the
sensor in the MU calculation
->
SENS:CORR:SGAM:STAT OFF // Turns off Single Point Gamma
Correction in order to include the
mismatch between the DUT and the
sensor in the MU calculation
->
FREQ 50MHz // Sets the measurement frequency to 50
MHz
->
SENS:MUNC:SGAM:TYPE TABLe // Selects Table-Based Gamma for the
DUT
->
SENS:MUNC:STAT ON // Turns on the RTMU function
->
FETCH:MUNC? // Queries the measured power and
calculated MU
->
MEM:TABL:SEL “SParam1” // Selects the S-Parameter table named
“SParam1”
->
MEM:TABL:FREQ 50MHz // Inputs a frequency of 50 MHz into the
selected table
->
MEM:TABL:SPAR S11,0.1,150 // Inputs the S11 magnitude-phase pair
values; 0.1 for magnitude, and 150
o
for
phase
->
MEM:TABL:SPAR S12,0.9,45 // Inputs the S12 magnitude-phase pair
values; 0.9 for magnitude, and 45
o
for
phase
