*PSC <Function>
POWER ON STATUS CLEAR determines whether the contents of the ENABle regis-
ters are preserved or reset during power-up.
The query form *PSC? reads out the contents of the power-on-status-clear flag. The
response can be 0 or 1.
Parameters:
<Function> 0 | 1
0
Causes the contents of the status registers to be preserved.
Thus a service request can be generated when switching on the
instrument, if the status registers ESE and SRE are suitably con-
figured.
1
Resets the registers.
*RST
RESET sets the instrument to a defined default status. The command essentially cor-
responds to pressing [PRESET]. This command clears the Enable and NTRansition
parts of the Operation and Questionable registers and fills the PTRansition part with 1.
In order to start a remote control program with a defined initial device status use com-
mand
*RST
or
SYSTem:PRESet
to preset the instrument. Then use command
*CLS
to
clear the ESR Event status register e.g. in case of an aborted synchronization.
*SRE <Value>
SERVICE REQUEST ENABLE sets the service request enable register to the indica-
ted value. Bit 6 (MSS mask bit) remains 0. This command determines under which
conditions a service request is generated. The query form
*SRE?
reads the contents of
the service request enable register in decimal form. Bit 6 is always 0.
Parameters:
<Value> 0 to 255
*STB?
READ STATUS BYTE QUERY reads out the contents of the status byte in decimal
form.
Usage: Query only
*TRG
TRIGGER initiates a measurement or a sweep.
