Description:
This command lets you specify whether or not the Service Request enable register and the Event Status
enable register should be cleared (all bits reset to 0) at power-up.
The settings of the Service Request enable register and the Event Status enable register are saved in
nonvolatile memory when you turn the analyzer off. These settings can be recalled when you turn the
analyzer on, but only if the Power-on Status Clear (PSC) flag is reset to 0. When the PSC flag is set to 1,
the two enable registers are cleared at power-up. Use *PSC to specify the state of the PSC flag.
The number last specified with *PSC is saved in nonvolatile memory, so it is not affected when you turn
the analyzer off and on. It is also not affected by the *RST command.
If you want the analyzer to generate a service request at power-up, bit 7 of the Event Status enable
register and bit 5 of the Service Request enable register must be set. This is only possible if the PSC flag
is reset to 0.
The query returns the current state of the PSC flag.
