Example
:STAT:OPER:PTR 255 sets the bits of the operation positive transition register
to 0000000011111110.
:STATus:OPERation:PTRansition?
Syntax
:STATus:OPERation:PTRansition?
Function
Returns the contents of the operation positive transition register as an integer
that, when converted to a binary number, represents the bit values of the
register.
Example
:STAT:OPER:PTR 12;PTR? returns 12.
:STATus:QUEStionable:CONDition?
Syntax
:STATus:QUEStionable:CONDition?
Function
Returns the contents of the questionable condition register as an integer that,
when converted to a binary number, represents the bit values of the register.
The attenuator only uses bit 1 of the register. Bit 1, the settling bit, is set when
the attenuator is in the process of adjusting the actual attenuation.
Example
:STAT:QUES:COND?
:STATus:QUEStionable:ENABle
Syntax
:STATus:QUEStionable:ENABle <space> <NRf>
Function
Sets the bits in the questionable enable register. The NRf value is rounded to the
nearest integer and converted to a binary number. The bits of the register are set
to match the bit values of the binary number.
Example
:STAT:QUES:ENAB 32.8 sets bit 0 and bit 5 of the questionable enable register
to 1.
:STATus:QUEStionable:ENABle?
Syntax
:STATus:QUEStionable:ENABle?
Function
Returns the contents of the questionable event enable register as an integer
that, when converted to a binary number, represents the bit values of the
register.
Example
:STAT:QUES:ENAB 23;ENAB? returns 23.
:STATus:QUEStionable[:EVENT]?
Syntax
:STATus:QUEStionable[:EVENT]?
Function
Returns the contents of the questionable event register as an integer that, when
converted to a binary number, represents the bit values of the register
Example
:STAT:QUES:EVENT?
