Displaying Measurement Result As Deviation From Reference Value (Deviation Measurement Mode) - Agilent Technologies 4288A Programming Manual

Displaying measurement result as deviation from reference value
(deviation measurement mode)
You can use the deviation measurement mode to display a relative measurement result as
deviation from the reference value instead of displaying its absolute value. To turn
ON/OFF the deviation measurement mode, use the following commands.
• :CALC1:MATH:STAT on page 149
• :CALC2:MATH:STAT on page 152
You can select from two modes in the deviation measurement mode: displaying the
deviation as it is or displaying the deviation as a percentage relative to the reference value.
To set the deviation measurement mode, use the following commands.
• :CALC1:MATH:EXPR:NAME on page 148
:CALC2:MATH:EXPR:NAME on page 151
•
To set the reference value in the deviation measurement mode, use the following
command.
:DATA {REF1|REF2} on page 172
•
The table below shows the relationship between the setups using the above commands and
the values displayed as the measurement result.

NOTE The measured value read out by the GPIB command is a calculation result based on the
above setup. For judgment in the comparator function, the measurement result is used as is
regardless of the setup. (Refer to the data processing flow in the Operation Manual.)
