4. Populate Table 28 with the Shunt Phase Error. Obtain the phase error from the A40B specifications
or phase calibration process.
5. Starting with step 8, Table 28, source the specified phase with the specific signal and frequency
parameters from the Product.
6. Measure with the phase meter and record in the Measured Product Output column.
7. Continue with the remainder of the steps in Table 28.
8. Complete steps 8 to 19 in Table 28 for 100 mA.
9. Set the Product to STBY.
10. Replace the 100 mA shunt with the 5 A shunt. For current >3.1 A connect the shunt input to SENSE
VZ LO/30 A.
11. Complete steps 20 and 21, Table 28.
12. Set the product to STBY.
13. Replace the 5 A shunt with the 20 A shunt.
14. Complete the remainder of the steps in Table 28.
15. Set the Product to STBY when finished.
16. Calculate the Product output as follows:
17. With all steps in the 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
properly modified by your Guardbanding method.
