The generator behaves as follows when it is turned on:
Instrument Mode
At power on, the generator will return to the same mode as it was powered
down. Normally, once it has booted, the instrument is ready for either front
panel operation of remote operation.
Registers and Filters
At power on, the state of the registers and filters is:
All registers and filters are set to its initial state except the PON bit of the
Standard Event Status Register. The PON (Power ON) event bit indicates
that an off-to-on transition has occurred in the device’s power supply.
All bits of Positive Transition Filter will be set and all bits of the Negative
Transition Filter will be cleared.
Local Mode
In Local Mode, all the front panel controls are responsive and control the
instrument.
Remote Mode
In Remote Mode, the front panel controls are inoperative and the instrument
is controlled by a remote client. The front panel display reflects the remote
programming commands received.
The instrument automatically enters remote mode when a command has
been received from the remote client. This is indicated by a small icon on
right hand side of the display.
Returning to Local Mode
To return to local mode, press the front panel Graph (Local) key. When you
power-cycle the instrument, it will also start in local mode.
Overheat Protection
The generator protects itself from damage by overheating by shutting down
itself in such cases. If the temperature exceeds a certain threshold the
instrument will immediately shut down itself as mentioned and a self-test
error will be stored in the instrument’s error queue when the instrument is
switched on again.
