3 53220A/53230A Measurements
MEASure:SPERiod? [<channel>]
CONFigure:SPERiod [<channel>]
-
channel
is counter channel 1 or 2, specified as
(@1)
or
(@2)
.
Single-Period Measurement Examples
// using MEASure? - make a single-period measurement on
// channel 1
*RST
// reset to start from known state
MEAS:SPER? (@1)
---------------------------------------------------------
// using CONFigure - make a single-period measurement on
// channel 1; start measurement when signal reaches 1.5V
// threshold
*RST
// reset to start from known state
CONF:SPER (@1)
INP:LEV 1.5 // set 1.5V threshold level

Notes
1. For period-averaging measurements rather than single-period measure-
ments, use the
MEASure:PERiod?
or
CONFigure:PERiod
commands.
2. Setting an absolute threshold level disables the counter’s auto-level func-
tion.
CONFigure
and
MEASure
enable auto-leveling at 50% (0V).
3. See Chapter 4 for information on input signal conditioning, including
threshold level and sensitivity.
