WFMDB:WFMDB3:
PERSISTENCE:MODE?
might return VARPERSIST, indicating
that the persistence mode for waveform database 3 is set to Variable.
WFMDB:WFMDB<x>:PERSistence:SAMPles? (Query Only)
This query returns the sample count in effect for the Variable persistence mode of
the specified WfmDB. The WfmDB is specified by x, which can be 1 through 4.
The count applies to the Variable persistence mode which can be selected with the
command WFMDB:WFMDB<x>:PERSistence:MODe VARPersist.
This query has no equivalent set command, since the number of samples cannot be
set directly. The sample count returned is the product of the number of Waveforms
specified (see the WFMDB:WFMDB<x>:PERSistence:COUNt command) and
the current record length (see the HORizontal:MAIn:RECordlength command).
The count returned by this query can also be seen in the Samples readout in the
Persistence section of the Wfm Database Setup dialog box.

Examples
WFMDB:WFMDB<1>:PERSistence :SAMPles? might return 50000, indicating
that the oldest waveforms will be dropped from the database 1 as the sample
count exceeds 50000 samples.
WFMDB:WFMDB<x>:SOURce
This command sets or queries the source of the WfmDB specified by x, which
can be 1 through 4. This command can optionally set the timebase. This is the
equivalent to selecting a s
ource (and timebase) in the Source control for the
Database1 or the Database2 sections of the WfmDB Setup dialog box. If you do
not set the timebase, the default is Main.
