Defaults and user setups

Model 2790 can be restored to one of two default setup configurations (FACTory or
*RST). The four user-saved setups (SAV0, SAV1, SAV2, or SAV3) can not be set as power
on default settings. As shipped from the factory, Model 2790 powers up to the factory
(FACT) default settings.

The factory default setup provides continuous triggering, while the *RST default setup
places the Model 2790 in the one-shot trigger mode. With one-shot triggering, a measure-
ment is performed whenever the TRIG key is pressed or an initiate command is sent over
the remote interface.
The factory and *RST default settings are listed in
between the two default setups are indicated by checkmarks (✓).
For remote programming, the SYSTem:PRESet and *RST commands are used to reset the
instrument. The *RST command returns the instrument to the *RST defaults and, for the
most part, the SYSTem:PRESet command returns the instrument to the factory default
conditions. The exceptions are explained as follows:
•
•
The instrument will power up to whichever default setup (FACT or *RST) is saved as the
power-on setup.

Closed channels can be saved in a user setup (SAV0, SAV1, SAV2, or SAV3).
When the setup is restored, those channels (and only those channels) will be
closed. FACT and *RST defaults opens all channels.
Auto scan and auto channel configuration — FACTory defaults disable auto scan
and auto channel configuration, while SYSTem:PRESet has no effect. The *RST
defaults (front panel and remote operation) have no effect.
Memory buffer auto clear — FACTory defaults enable buffer auto clear, while
SYSTem:PRESet has no effect. The *RST defaults (front panel and remote
operation) have no effect.
At the factory, the factory default setup is saved as the SAV0, SAV1, SAV2, and
SAV3 setups.
