Data Log and Digitizing Local Remote Interaction
Loss of data possible - local to remote transition clears instrument memory:
When data logging or
digitizing
to memory
, if you access the instrument from remote (send a SCPI or common command)* and
then return to local (by pressing
[Local]
), the readings in memory are cleared and the instrument returns
to Continuous mode.
For data logging only, you can prevent this situation by data logging to a file instead of to memory (see
for details). You can also prevent this from happening for data logging or digitizing by tak-
ing steps to keep the instrument from being accessed from remote. To prevent remote access, you may
want to disconnect the LAN, GPIB, and USB interface cables from the instrument before starting the meas-
urements. To prevent remote access via LAN, you can connect the instrument behind a router to minimize
the possibility of remote access. You can also disable the various I/O interfaces from the front panel menus
under
[Utility]
>
I/O Config
.
To view the status of a data logging or digitizing operation remotely, use the instrument’s
. The Web User Interface monitor does not set the instrument to remote.
*When accessed from remote, the instrument will continue data logging or digitizing to completion, and you can retrieve the read-
ings from remote.
