Status Reporting in SCPI
The status reporting implemented in the XTR is primarily dictated by the
SCPI standard. This section provides a high level review of the standard
status reporting required by SCPI and then covers the XTR specific
reporting that is implemented within the SCPI status reporting
framework.
Figure 5-16 is taken from the SCPI 99 standard and shows the minimum
status reporting requirements for a SCPI compliant device.
Throughout this chapter, figures are used to explain the relationship
between the registers, enable/disabling register and their summary bits.
The figures use four logical symbols to demonstrate the relationship
between the register. The “!” block represents logical not or complement
of the input signal. The “&” block represents the logical AND operator.
The “|” block represents the logical OR operation. The “+” block
represents the logical OR of all the bits from the enable register. The
model has several ellipses which are there to indicate that the pattern of
logic shown is repeated for all bits in the registers.
