Limit Test Commands
SWAVeform
10 OUTPUT 707;”:LTEST:SSUMMARY DISK,TEST”
Query :LTESt:SSUMmary?
The query returns the current specified destination for the summary.
Returned Format [:LTESt:SSUMmary] {OFF | DISK {,<filename>}}<NL>
Example The following example returns the current destination for the summary.
10 DIM SUMM$[50]
20 OUTPUT 707;”:LTEST:SSUMMARY?”
30 ENTER 707;SUMM$
SWAVeform
Command :LTESt:SWAVeform <source>, <destination>[,<filename>[, <format>]]
This command saves waveforms from a channel, function, TDR response or waveform mem-
ory in the event of measurement limit test termination, as specified by the :LTEST:RUNTil
command. Each waveform source can be individually specified, allowing multiple channels,
responses or functions to be saved to disk or waveform memories. Setting a particular source
to OFF removes any waveform save action from that source.
NOTE This command operates on waveform and color grade gray scale data which is not compatible with Jitter Mode.
Do not use this command in Jitter Mode. It generates a “Settings conflict” error.
<source> {CHANnel<N> | FUNCtion<N> | WMEMory<N> | RESPonse<N>}
<destination> {OFF | WMEMory<N> | DISK}
<filename> An ASCII string enclosed in quotation marks. If no filename is specified, the assigned file-
name will be MeasLimitChN_X, MeasLimitFnN_X, MeasLimitRspN_X, or
MeasLimitMemN_X, where X is an incremental number assigned by the instrument. If no
path is specified, the default path will be
D:\User Files\waveforms. (C drive on
86100A/B instruments.)
NOTE If the selected waveforms of consecutive limit tests are to be stored in individual files, omit the <filename>
parameter. The waveforms will be stored in the default format (INTERNAL) using the default naming scheme.
<format> {TEXT [,YVALues | VERBose] | INTernal}
where INTernal is the default value, and VERBose is the default value for TEXT.
Example The following example turns off the saving of waveforms from channel 1 in the event of a limit
test failure.
10 OUTPUT 707;”:LTEST:SWAVEFORM CHAN1,OFF”
Query :LTESt:SWAVeform? <source>
The query returns the current state of the :LTESt:SWAVeform command.
Returned Format [:LTESt:SWAVeform]<source>, <destination>, [<filename>[,<format>]]<NL>
Example The following example returns the current parameters for saving waveforms in the event of a
limit test failure.
10 DIM SWAV$[50]
20 OUTPUT 707;”:LTEST:SWAVEFORM? CHANNEL1”
30 ENTER 707;SWAV$
