Limit Test Commands
SSCReen
This command saves a copy of the screen in the event of a failure. OFF turns off the save
action. DISK saves a copy of the screen to disk in the event of a failure. <filename> is an
ASCII string enclosed in quotations marks. If no filename is specified, a filename will be
assigned. The default filename is MeasLimitScreenX.bmp, where X is an incremental num-
ber assigned by the instrument.
NOTE The save screen options established by the commands LTESt:SSCReen DISK, LTESt:SSCReen:AREA, and
LTESt:SSCReen:IMAG are stored in the instrument’s memory and will be employed in consecutive save screen
operations, until changed by the user. This includes the <filename> parameter for the LTESt:SSCReen DISK
command. If the results of consecutive limit tests must be stored in different files, omit the <filename>
parameter and use the default filename instead. Each screen image will be saved in a different file named
MeasLimitScreenX.bmp, where X is an incremental number assigned by the instrument.
The filename field encodes the network path and the directory in which the file will be
saved, as well as the file format that will be used. The following is a list of valid filenames.
If a filename is specified without a path, the default path will be
D:\User Files\screen images. The default file type is a bitmap (.bmp). The fol-
lowing graphics formats are available by specifying a file extension: PCX files (.pcx), EPS
files (.eps), Postscript files (.ps), JPEG (.jpg), TIFF (.tif) and GIF files (.gif).
Example The following example saves a copy of the screen to the disk in the event of a failure. Addi-
tional disk-related controls are set using the SSCReen:AREA and SSCReen:IMAGe com-
mands.
10 OUTPUT 707;”:LTEST:SSCREEN DISK”
Query :LTESt:SSCReen?
The query returns the current state of the SSCReen command.
Returned Format [:LTESt:SSCReen] {OFF | DISK [,<filename>]}<NL>
Example The following example returns the destination of the save screen when a failure occurs.
10 DIM SSCR$[50]
20 OUTPUT 707;”:LTESt:SSCREEN?”
