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

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:NSELec

To set or read the status registers of another phase, first use:

INSTrument:NSELect <n>

where <n> is the phase number. Then send the appropriate register commands.

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 <n>

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 <n>

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

Enable STAT:QUES:INST:I

SUM:ENAB <n>

A register that functions as a mask for enabling

specific bits from the Event register. It is a read/write

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.
