3 53220A/53230A Measurements
116 Keysight 53220A/53230A User’s Guide
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
