The dierence between the measured value of the DUT and a
previously stored reference value are displayed. The formula used
to calculate the deviation is as follows.
1ABS = X 0 Y
Where,
X: The measured value of the DUT
Y: The stored reference value
1% (Delta percent) deviation measurement
The dierence between the measured value of the DUT and a
previously stored reference value are displayed as a percentage of
the reference value. The formula used to calculate the percent
deviation is as follows.
1% = (X 0 Y) / Y 2 100 [%]
Where,
X: The measured value of the DUT
Y: The stored reference value
Front Panel Operation for the Deviation Measurement Function
Perform the following steps to execute the deviation measurement
function.
1. Move the cursor to the REF A eld to enter the reference
value for the primary parameter. The following softkey will be
displayed.
NNNNNNNNNNNNNNNNNNNNNNNNNN
MEA-SURE
When the device which has a reference value is connected,
pressing this MEA-SURE , the 4284A measures the device, and the
measurement results are entered as a reference value for REF A
and REF B values.
2. Enter the reference value for the primary parameter using
MEA-SURE or the numeric entry keys.
3. Move the cursor to the (REF) B eld to enter the reference
value for the secondary parameter. The following softkey will be
displayed.

NNNNNNNNNNNNNNNNNNNNNNNNNN
MEA-SURE
When the device is to be used as the reference value is
connected, MEA-SURE is pressed, the 4284A measures the device,
and the measurement results are entered as a reference value for
REF A and REF B values.
4. Enter the reference value for the secondary parameter using
MEA-SURE or the numeric entry keys. If the reference values for A
and B are entered using MEA-SURE in step 2, skip this step.
5. Move the cursor to the DEV A eld. The following softkeys will
be displayed.
