7.4 Questionable Instrument Isummary Status Group
Although only one group of Questionable Instrument Isummary Status registers is shown in Figure
7-1, there are actually three identical register groups. With the exception of bit 13, the register
structure is the same as the Questionable Status group. These three register groups monitor the
status signals of each individual phase of the three-phase AC source. To determine which phase
of the AC source is currently selected, use:
INSTrument:NSELect?
To set or read the status registers of another phase, first use:
INSTrument:NSELect
where is the phase number. Then send the appropriate register commands.
Register Command Description
Condition STAT:QUES:INST:I
SUM:COND? A register that holds real-time status of the circuits
being monitored. It is a read-only register.
PTR Filter STAT:QUES:INST:I
SUM:PTR A positive transition filter that functions as described
under STAT:QUES:INST:ISUM:NTR|PTR
commands in chapter 4. It is a read/write register.
NTR Filter STAT:QUES:INST:I
SUM:NTR A negative transition filter that functions as described
under STAT:QUES:INST:ISUM:NTR|PTR
commands in chapter 4. It is a read/write register.
Event STAT:QUES:INST:I
SUM:EVEN? A register that latches any condition that is passed
through the PTR or NTR filters. It is a read-only
register that is cleared when read.
Enable STAT:QUES:INST:I
SUM:ENAB A register that functions as a mask for enabling
specific bits from the Event register. It is a read/write
register.
Table 7-4: Questionable Instrument Isummary Status registers
The outputs of the Questionable Instrument Isummary Status group are logically-ORed into the
Isum bit (13) of the Questionable Condition register.
