53220A/53230A Measurements 3
Keysight 53220A/53230A User’s Guide 117
Notes
1 If the phase format is CENTered, a typical phase measurement for signals 270°
out of phase for example, could be -9.10799485574691E+001. If the format
was POSitive, the phase difference measured might typically be
+2.68904450044343E+002.
2 Phase measurements represent the signal phase of the first channel relative to
the second channel in the pair. For example, if the phase format is CENTered
and the signal on channel 2 is delayed for a period equivalent to 90
°, the
measurement will be 90
° for the channel pair (@1),(@2). If under the same
signal conditions the channel pair were specified as (@2),(@1), the
measurement would be -90 degrees.
Single-period
A form of time interval measurement - the single-period measurement, is based
on a single waveform cycle. Single-period measurements provide measurement
of “single-shot” or one cycle events; and allow analysis of signal characteristics
(e.g. jitter) that would otherwise be averaged out with standard (averaging) period
measurements.
The commands used to make single-period measurements are:
MEASure:SPERiod? [<channel>]
CONFigure:SPERiod [<channel>]
