Dutycycle - HP 54501A Programming Reference Manual

DUTycycle
DUTycycle
command/query
The
:MEASURE:DUTYCYCLE
command places the instrument in the
continuous measurement mode and
starts
the Dutycycle measurement.
The
DUTYCYCLE
query measures and outputs the duty cycle
of the
signal specified by
the
SOURCE command. The signal
must be
displayed
for the measurement to be made. The
value
returned for duty cycle
is
the
ratio of the positive pulse width to period.
The positive pulse width and
the
period of
the specified signal are
measured, then the duty cycle is
calculated.
The
duty cycle
is
calculated
with the following
formula:
duty cycle
=
+ pulse width/period
Command Syntax:
:MEASure:DUTycycle
Example: OUTPUT 707;":MEASURE:DUTYCYCLE"
Query Syntax: :MEASure:DUTycycle?
Returned Format: [MEASure:DUTycycle]
< value >
<NL>
Where:
<
value
> ::
=
ratio of +pulse
width to period (exponential
-
NR3 format)
Example: DIM Dc$[50]
OUTPUT 707;":MEASURE:DUTYCYCLE?"
ENTER
707; Dc$
PRINT Dc$
