Defaults and user setups
Model 2750 can be restored to one of two default setup configurations (FACTory or
*RST), or three user-saved (SAV0, SAV1, or SAV2). As shipped from the factory,
Model 2750 powers up to the factory (FACT) default settings.
NOTE Closed channels can be saved in a user setup (SAV0, SAV1, or SAV2). When the
setup is restored, those channels (and only those channels) will be closed. FACT
and *RST defaults opens all channels.
The factory default setup provides continuous triggering, while the *RST default setup
places the Model 2750 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 Table 1-4. Setting differences (Set Diff)
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:
• 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 opera-
tion) have no effect.
The instrument will power up to whichever default setup is saved as the power-on setup.
NOTE At the factory, the factory default setup is saved as the SAV0, SAV1, or SAV2
setups.
