4.7.3 STATus Commands
Command
The PRESet command is an event that configures the SCPI and device-
dependant status data structures. The mandatory mechanism is defined in
part by the IEEE 488.2.
:STATus:PRESet
It clears all status group event registers. Presets the status group, enables
PTR and NTR registers as follows:
ENABle = 0x0000, PTR = 0xffff, NTR = 0x0000.
4.7.4 STATus Questionable Data Register command subsystem
Introduction
The Questionable Data register group provides information about the quality
or integrity of the instrument. Any or all of these conditions can be reported
to the Questionable Data summary bit through the enable register.
The 81150A / 81160A has two levels of error reporting mechanism called
“warnings” and “errors”. Checking for warnings and errors is always
enabled by switching on the output(s). A warning is generated when due to
a combination of worst case uncertainties at the current settings of all
relevant parameters, an invalid signal is output. A warning will be reflected
in the QUEStionable data register structure. See the following table for
definitions.
