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 b180
°
.
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
