Use the CARDATA command with the –r switch to report how much data can be
returned.
cardata -r <moduleA> <moduleB>
The <moduleA> and <moduleB> arguments define the pair of 92A96 Modules
containing the acquired data. The response to the query is a text string separated
commas indicating the first sequence number, sequence count, and the trigger
position.
Use the CARDATA command with the –h switch to return the acquisition data
header that is a combination of the headers of both modules. When you use the
–h switch, the command returns only the header information.
cardata -h <moduleA> <moduleB>
The <moduleA> and <moduleB> arguments define the pair of 92A96 Modules
containing the acquired data. The channel name information is taken from
<moduleA>. The acquisition memory depth is the total number of correlated
sequences. The data format of the header is identical to the header returned by
the PCL ACQHDR? query.
By default the CARDATA command returns acquired data only. There may be
times when you want to return both the header and data information. In this case
you can use the CARDATA command with –hd switch.
cardata -hd <moduleA> <moduleB>
The CARDATA command returns timestamp information. While executing the
CARDATA command, there may be duplicate timestamp values. To keep the
timestamp values unique, the CARDATA command adjusts the timestamp values
by adding 3 ns to the first duplicate timestamp value, 5 ns to the second
duplicate timestamp value, and 8 ns to the third duplicate timestamp value. The
timestamp corrections are determined for each data record.
Use the optional –t switch with the CARDATA command if you do not want to
adjust the timestamp values. If you use the –t switch, duplicate timestamp values
can appear in the resultant output.
cardata -t <moduleA> <moduleB>
The –t switch can be helpful while debugging code for the system-under-test.
