Measure Commands
RISetime
RISetime
Command
:MEASure:RISetime [<source>]
Measures the rise time of the first displayed edge by measuring the time at the lower thresh-
old of the rising edge, measuring the time at the upper threshold of the rising edge, then cal-
culating the rise time with the following algorithm:
Rise time = time at upper threshold point
–
time at lower threshold point.
Sources are specified with the MEASure:SOURce command or with the optional parameter
following the RISetime command.
Mode
All instrument modes.
<source>
{CHANnel<N> | FUNCtion<N> | RESPonse<N> | WMEMory<N> | CGRade}
Where CHANnel<N>, FUNCtion<N>, RESPonse<N>, and WMEMory<N> apply in Oscillo-
scope and TDR modes only, and CGRade in Eye mode only.
<N>
For channels, functions, TDR responses and waveform memories: 1, 2, 3, or 4.
With standard measurements selected, the lower threshold is at the 10% point and the upper
threshold is at the 90% point on the rising edge.
Query
:MEASure:RISetime? [<source>]
The query returns the rise time of the specified source.
Returned Format
[:MEASure:RISetime] <value>[,<result_state>]<NL>
<value> is the rise time in seconds. If SENDvalid is ON, the <result_state> is returned with
the measurement result. Refer to
for a list of the result states.
Example
10 OUTPUT 707;”:SYSTEM:HEADER OFF”
20 OUTPUT 707;":MEASURE:RISETIME?"
SCRatch
Command
:MEASure:SCRatch
Clears the measurement results from the screen.
Example
This example clears the current measurement results from the screen.
10 OUTPUT 707;":MEASURE:SCRATCH"
SENDvalid
Command
:MEASure:SENDvalid {ON | OFF | 1 | 0}
E
nables the result state code to be returned with the :MEASure:RESults? query and with indi-
vidual measurements. If SENDvalid is off, any questionable restults are returned as
9.999E+37. If SENDvalid is on, current values are returned for any questionable results.
Query
:MEASure:SENDvalid?
The query returns the state of the Sendvalid control.
Returned Format
[:MEASure:SENDvalid] {0 | 1}<NL>
Examples
10 OUTPUT 707;":MEASURE:SENDVALID ON"
