74. From step 89, Table 16, output from the DUT and wait 3 minutes for the output to settle. Measure
with the meter and record the 8588A measurement in the DMM Reading on Shunt Output [V]
column.
75. After step 89 is complete, disconnect the shunt output cable from the 8588A and connect to the
5790B Input 2.
76. Set the 5790B for Input 2, Auto range, High resolution ON, GUARD ON.
77. Connect heavy gauge guard cable between the DUT and the 5790B.
78. From step 90, Table 16, output from the DUT and measure with the 5790B. Record the 5790B
measurement in the DMM Reading on Shunt Output [V] column. Complete steps 90 to 92.
79. Set the product to STBY.
80. For all steps, calculate the Product output with the formula below. Use the appropriate conversion
to convert from base units to units for the specific evaluation step.
81. With the entire table populated, evaluate each step for compliance to limits. If Guardbanding is to
be applied, create a table from the example in this manual where the acceptance limits are the
properly modified by your Guardbanding method.
