Command

Example

COMPare Subsystem

COPY

COPY

:MACHine{12}:COMPare:COPY

The COPY command copies the current acquired State Listing for the specified machine into the Compare Listing template. This makes the current acquisition the reference listing. It does not affect the compare range or channel mask settings.

OUTPUT XXX;":MACHINE2:COMPARE:COPY"

DATA

Command:MACHine{12}:COMPare:DATA {<label_name>,<line_num>,<data_pattern> <line_num>,<data_pattern>[, <data_pattern>]... }

The DATA command allows you to edit the compare listing image for a given label and state row. When DATA is sent to an instrument where no compare image is defined (such as at power-up) all other data in the image is set to don’t cares.

Not specifying the <label_name> parameter allows you to write data patterns to more than one label for the given line number. The first pattern is placed in the leftmost label, with the following patterns being placed in a left-to-right fashion as seen on the Compare display. Specifying more patterns than there are labels simply results in the extra patterns being ignored.

Because don’t cares (Xs) are allowed in the data pattern, it must always be expressed as a string. You may still use different bases, but don’t cares cannot be used in a decimal number.
