Measure Commands
RESults?
pwidth = time at the second falling edge – time at the first rising edge
Mode Oscilloscope mode only
<source> {CHANnel<N> | FUNCtion<N> | WMEMory<N>}
<N> For channels: Value is dependent on the type of plug-in and its location in the instrument.
For functions: 1 or 2. For waveform memories (WMEMORY): 1, 2, 3, or 4.
Query :MEASure:PWIDth? [<source>]
The query returns the measured width of the first positive pulse of the specified source.
Returned Format [:MEASure:PWIDth] <value>[,<result_state>]<NL>
<value> is the width of the first positive pulse on the screen in seconds. If SENDvalid is ON,
the <result_state> is returned with the measurement result. Refer to Table 18-4 on
page 18-39 for a list of the result states.
Example 10 OUTPUT 707;”:SYSTEM:HEADER OFF”
20 OUTPUT 707;”:MEASURE:PWIDTH?”
RESults?
Query :MEASure:RESults?
Returns the results of the continuous measurements which are selected by using “JIT-
Ter:SELect” on page 15-2 or “SINTegrity:SELect” on page 15-4. The measurement results
always include only the current results. If SENDvalid is ON, the measurement results state is
returned immediately following the measurement result. Except in Jitter Mode, the measure-
ment results include the current, minimum, maximum, mean, standard deviation, and statis-
tical sample size (n-samples) of each measurement. If more than one measurement is
running continuously, the values shown in Table 18-4 on page 18-39 will be duplicated for
each continuous measurement from the first to last (top to bottom) of display. There may be
up to four continuous measurements at a time.
If :MEASure:SENDvalid is off, any questionable restults are returned as 9.999E+37, except
for the n-samples field. If :MEASure:SENDvalid is on, current values are returned for any
questionable results.
In Jitter Mode, the current result for up to four selected jitter mode measurements are
returned. If limit testing is turned on, limit failures, limit total tests, and limit status values are
returned.
NOTE In some cases, remote results on statistical measurements may display incorrect ASCII mapping, such as a ç
symbol in lieu of the Σ (sigma) symbol.
Returned Format [:MEASure:RESults] <result list><NL>
<result list> A list of the measurement results, as in Table 18-3, separated with commas.
