Measure Commands
JITTer:TJ:DEFine
Restrictions Jitter mode. Software revision A.04.00 and above (86100C instruments).
Returned Format [:MEASure:JITTer:TJ] <value><NL>
Example 10 OUTPUT 707;”:SYSTEM:HEADER OFF”
20 OUTPUT 707;”:MEASURE:JITTER:TJ?”
JITTer:TJ:DEFine
Command :MEASure:JITTer:TJ:DEFine <level_value>
Sets the Bit Error Ratio (BER) at which total jitter is measured. The default value is 10^-12.
Restrictions Jitter mode. Software revision A.04.10 and above (86100C instruments). Option 200,
Enhanced Jitter Analysis Software.
Query :MEASure:JITTer:TJ:DEFine?
Returned Format [:MEASure:JITTer:TJ:DEFine] <level_value><NL>
Example 10 OUTPUT 707;”:MEASure:JITTer:TJ?”
JITTer:UNITs
Command :MEASure:JITTer:UNITs {SECond|UINTerval}
Sets the units used for jitter mode measurements, seconds or unit interval.
Restrictions Jitter mode. Software revision A.04.00 and above (86100C instruments).
Query :MEASure:JITTer:UNITs?
This query returns the current setting for jitter mode measurement units.
Returned Format [:MEASure:JITTer:UNITs] {SEC|UINT}<NL>
Example :MEASure:JITTer:UNITs SEC
NWIDth
Command :MEASure:NWIDth [<source>]
Measures the width of the first negative pulse on the screen using the mid-threshold levels of
the waveform (50% levels with standard measurements selected). The source is specified
with the MEASure:SOURce command or with the optional parameter following the NWIDth
command. The algorithm is, if the first edge on screen is rising, then
nwidth = time at the second rising edge – time at the first falling edge
else,
nwidth = time at the first rising edge – time at the first falling edge.
<source> is {CHANnel<N> | FUNCtion<N> | WMEMory<N>}. <N> for channels 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.
Mode Oscilloscope mode only
Query :MEASure:NWIDth? [<source>]
The query returns the measured width of the first negative pulse of the specified source.
Returned Format [:MEASure:NWIDth] <value>[,<result_state>]<NL>
