3 53220A/53230A Measurements
The commands used to make phase measurements are:
MEASure:PHASe? [<channel_pair>]
CONFigure:PHASe [<channel_pair>]
FORMat:PHASe {AUTO|POSitive|CENTered}
FORMat:PHASe? (query form)
- channel_pair settings are (@1),(@2)and (@2),(@1). The first channel
of the pair is relative to the second channel.
- AUTO automatically selects whether the phase difference will be returned as
a positive value between 0
° and 360°, or a positive or negative value between
+
180°.
- POSitive returns the measured phase difference as a positive value
between 0
° and 360°.
- CENTered returns the measured phase difference as a positive or negative
value between +
180°.
Phase Measurement Examples
// using MEASure? - measure the phase difference between
// channels 1 and 2
*RST // reset to start from known state
FORM:PHAS CENT // display result as pos or neg
MEAS:PHAS? (@1), (@2)
---------------------------------------------------------------------------------------------------------
// using CONFigure - measure the phase difference between
// channels 1 and 2, display result as a value between 0 and
// 360 degrees
*RST // reset to start from known state
CONF:PHAS (@1), (@2)
FORM:PHAS POS // display result as a positive value
