WFMDB:WFMDB<x
>:PERSistence:MODe, WFMDB:WFMDB<x>:
PERSistence:SAMPles?
Arguments
<NR1> (Range
: 1 - 2000) sets the waveform count used for acquiring databases
set to a persistence mode. The oldest waveforms accumulated in the database are
removed as the waveforms accumulate beyond the specified count.
Examples
WFMDB:WFMDB3:PERSISTENCE: COUNT 2E3 sets variable-persistence count for
waveform database 3 to 2000 waveforms.
WFMDB:WFMDB2:PERSISTENCE: COUNT? might return 1000, indicating that the
variable-persistence count for waveform database 2 is set to 1000 waveforms.
WFMDB:WFMDB<x>:PERSistence:MODe
This command sets or queries which persistence mode, Infinite or Variable, that the
specified WfmDB uses to accumulate waveform data. The WfmDB is specified by
x, which can be 1 through 4. The modes are described under Arguments, below.
Use of this command is equivalent to selecting Infinite or Variable in the
Persistence section of the Wfm Database Setup dialog box.

Syntax
WFMDB:WFMDB<x>:PERSistenc e:MODe {INFPersist | VARPersist}
WFMDB:WFMDB<x>:PERSistenc e:MODe?
Related Commands
WFMDB:WFMDB<x>:PERSistence:SAMPles?, WFMDB:WFMDB<x>:
PERSistence:COUNt
Arguments
INFPersist sets WfmDB<x> to Infinite persistence mode, which continues
displaying waveforms as they accumulate until the WfmDB<x> is c leared
manually or by a control change (switching the database to Variable
persistence, for example).
INFPERSIST is the default setting.
VARPersist sets the waveform database to Variable persistence mode.
Variable persistence keeps and displays accumulated data in the specified
database until the user-specified waveform count is surpassed. Each waveform
accumulated beyond the count removes the oldest waveform accumulated
earlier in the database.
Examples
WFMDB:WFMDB2:PERSISTENCE: MODE INFPERSIST sets the persistence mode
for waveform database 2 to Infinite.
