Status Subsystem (:STATus)
Chapter 4 207
:QUEStionable:PTRansition
Supported All
:STATus:QUEStionable:PTRansition <value>
:STATus:QUEStionable:PTRansition?
This command determines what bits in the Data Questionable Condition Register will
set the corresponding bit in the Data Questionable Event Register when that bit has a
positive transition (0 to 1).
The variable <value> is the sum of the decimal values of the bits that you want to
enable.
*RST N/A
Range 0–32767
Key Entry N/A
Remarks Refer to “Data Questionable Status Group” on page 120 and “Data
Questionable Transition Filters (negative and positive)” on page 122
for more information.
:QUEStionable[:EVENt]
Supported All
CAUTION This is a destructive read. The data in the register is latched until it is
queried. Once queried, the data is cleared.
:STATus:QUEStionable[:EVENt]?
This command returns the decimal sum of the bits in the Data Questionable Event
Register. For example, if the signal generator has just been connected to the line power
and the reference oscillator oven is cold (bit 4), a value of 16 is returned.
*RST N/A
Range 0–32767
Key Entry N/A
Remarks Refer to “Data Questionable Status Group” on page 120 and “Data
Questionable Event Register” on page 122 for more information.
The equivalent PTR or NTR filters must be set before the condition
register can set the corresponding bit in the event register.
