Stanford Research Systems SIM983, Operation And Service Manual

Page: 24 / 74

2 – 4 Description of Operation
If the output or an intermediate stage of the amplifier is driven beyond the
limits in the table on Page vi, large-signal behavior is not guaranteed.
2.4 Clock Stopping
The microprocessor clock of the SIM983 stops if the module is idle,
“freezing” the digital circuitry. The following actions “wake up” the
clock:
1. A power-on.
2. A press of a front-panel button.
3. Activity (send or receive) at the remote interface.
4. An overload.
The clock runs for as long as is necessary to complete a gain or o
ff
set
adjustment, or to communicate the output of a query through the
remote interface. However, the clock will remain active for as long
as the overload condition exists.
This default behavior can be modified with the remote com-
mand
AWAK . Setting AWAK
ON
will prevent the clock from stopping.
The module returns to AWAK OFF upon power-on.
