13. Receiver Phase Dynamic Accuracy
aPerform the "IF Amplifier Correction Constants" and "ADC Offset Correction
Constants" procedures (located in the "Adjustments and Correction Con-
stants" chapter of the Agilent 8753D Option 011 Service Guide).
bRepeat this performance test.
cIf it still fails, replace the A10 Digital IF assembly.
dRepeat the two adjustment procedures mentioned in this step and then re-
peat this performance test.
13. Receiver Phase Dynamic Accuracy
Perform this test to measure phase dynamic accuracy of each receiver chan-
nel.

Procedure Channel A Phase Dynamic Accuracy
1Refer to the " Receiver Dynamic Accuracy-Magnitude " portion of the
"Performance Test Record," for the values in the "Magnitude Value" column.
2Copy the values in the "Magnitude Value" column to the "Magnitude Value"
column of the "Receiver Dynamic Accuracy-Phase" portion of the
"Performance Test Record."
3For every receiver input power level, calculate "A" using the following formula:
