Instrument initialisation
The (factory) default setting of the AN680XX is applied when
o
applying a DCL, SDC to the GPIB interface.
o
ransmitting a *RST command
o
transmitting the first command after activating this emulation mode.
During initialisation, the AN680XX applies and activates the setting, that was
active just before power down.
The SM* however applies and activates the (factory) default setting of the
AN680XX.
This different behaviour has to the be taken in consideration.
It is strongly recommended to explicitly setup all necessary parameters
by applying the corresponding command.
The following table shows the (factory) default setting, applied by the SM*’s
emulation software.
