Table 66: Other commands
Instrument initialisation
The (factory) default setting of the HP8340 is applied when
o
applying the DCL, SDC to the GPIB interface.
o
transmitting the first command after activating this emulation mode.
During initialisation, the HP8340 applies and activates the backup register set
0.
The SM* however applies and activates the (factory) default setting of the
HP8340.
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.
