:STATus:QUEStionable:NTRansition
Syntax
:STATus:QUEStionable:NTRansition <space> <NRf>
Function
Sets the bits of the questionable negative transition register. The NRf value is
rounded to the closest integer and converted to a binary number. The bits of the
register are set to match the bits of the binary number.
Example
:STAT:QUES:NTR 256 sets the bits of the questionable negative transition
register to 0000000011111111.
:STATus:QUEStionable:NTRansition?
Syntax
:STATus:QUEStionable:NTRansition?
Function
Returns the contents of the questionable negative transition register as an
integer that, when converted to a binary number, represents the bit values of the
register.
Example
:STAT:QUES:NTR 12;NTR? returns 12.
:STATus:QUEStionable:PTRansition
Syntax
:STATus:QUEStionable:PTRansition <space> <NRf>
Function
Sets the bits of the questionable positive transition register. The NRf value is
rounded to the closest integer and converted to a binary number. The bits of the
register are set to match the bits of the binary number.
Example
:STAT:QUES:PTR 255 sets the bits of the questionable positive transition
register to 0000000011111110.
:STATus:QUEStionable:PTRansition?
Syntax
:STATus:QUEStionable:PTRansition?
Function
Returns the contents of the questionable positive transition register as an integer
that, when converted to a binary number, represents the bit values of the
register.
Example
:STAT:QUES:PTR 12;PTR? returns 12.
:STATus:PRESet
Syntax
:STATus:PRESet
Function
This command presets all the enable and transition registers in the questionable
and operation registers to the following settings:
• All bits in the ENABle registers are set to 0
• All bits in the positive transition registers are set to 1
• All bits in the negative transition registers are set to 0
Example
:STAT:PRES
