Calibration Table Setup for VMA
As shown in the previous demonstrations, the
Use Current Meas
feature is not available when using
the Vector Modulation Analysis (VMA) application. The following script populates the desired
Calibration Row with your selected settings in VMA.
%% Demo #2 | {Use Current Meas} for VMA

% Define Desired Cal Group
cal_group = 1;
% Define Mechanical Attenuation Range (must be divisable by 2)
mech_atten_range = 6;
elec_atten_raange = 6;
% Input ID (VISA, IP, etc.)
SA_address = 'USB0::0x2A8D::0x0D0B::MY49431812::0::INSTR'
SG_address = 'USB0::0x0957::0x1F01::MY53050777::0::INSTR'
% Create VISA objects for your X-Series Signal Analyzer and Power Source
my_SA = visa('keysight', SA_address);
my_SG = visa('keysight', SG_address);
