(Command/Query)
The command *SRE <mask> positions the service request mask register.
<mask> is a value in format <NR1>, from 0 to 255.
A value of bit at 1 enables the same-rank bit of the status register to request a service (bit of
the status register contains 1). A bit value at 0 neutralizes it.
To the question *SRE?, the instrument returns the value of the service demand mask register.
Response format:
<value><NL>
value in format <NR1> from 0 to 255.

(Query)
To the question *STB? the instrument returns the content of its status register (Status Byte
Register).
The bit 6 returned indicates the MSS value (Master Summary Status) (at 1 if the instrument
has a reason for requesting a service).
Contrary to RQS, it is not reset to zero after reading the status register (RQS is accessible only
by series recognition, and falls to 0 at its end).

(Command)
The command *TRG starts an acquisition in the current mode "single" or "continuous".
(Query)
To the question *TST?, the instrument returns the status of the autotest procedure.
Response format:
<0|1><NL>
responds 0 when the autoset is successful.
responds 1 when a problem has been detected.
(Command)
The command *WAI prevents the instrument from performing further commands as long as the
current command has not been terminated. This enables to synchronize the instrument with
the application program in progress on the controller.
