Command 

:LTESt:SWAVeform[?]

<source>,<destination>,[,<filename>[,<format>]]

Saves waveforms from a channel, function, histogram, TDR response, or
waveform memory in the event of a failure detected by the limit test. Each
waveform source can be individually specified, allowing multiple channels or
functions to be saved to disk or waveform memories. Setting a particular
source to OFF removes any waveform save action from that source.

<source>

{CHANnel<number> | FUNCtion<number> | HISTogram
| RESPonse<number> | WMEMory<number>}

<destination>

{OFF | WMEMory<number> | DISK}

When DISK is selected, a file name is required.

<filename>

A descriptive file prefix consisting of up to four characters. If no filename is
specified, the prefix defaults to CH1A..CH4B, FN1, FN2, FFT, HIST,
MEM1..MEM4, RSP1..RSP4.
