Example: Performing open/short/load correction
The example represents the remote control commands to configure the correction set-
tings.
// Configure the corrections settings:
// set the cable length between the DUT and the instrument
CORRection:LENGth 1 // the test leads are of 1m length
// ***************************
// Perform open correction on all frequencies
CORRection:OPEN:STATe 1
CORRection:OPEN[:EXECute]
// query if operation is complete and successfull
*OPC?
SYSTem:ERRor?
// ***************************
// Perform open correction on the current working point
CORRection:SPOT:OPEN[:EXECute]
// ***************************
// Perform short correction on all frequencies
CORRection:SHORt:STATe 1
CORRection:SHORt[:EXECute]
// Perform short correction on the current working point
CORRection:SPOT:SHORt[:EXECute]
// ***************************
// Save and restore a correction data set
// of a full or short correction
// !! not provided for spot and load correction data
CORRection:STORage:Save 2
// saves the data in memory slot 2
CORRection:STORage:RESTore 2
// recalls the correction data in memory slot 2
// ***************************
// Perform load correction on all frequencies
CORRection:LOAD:STATe 1
// Configure the expected value of the load
CORRection:SPOT:LOAD:STANdard 15,20
// Perform load correction at the current working point
CORRection:SPOT:LOAD[:EXECute]
