16.For each marker up to marker 5, read the values of D2 and D1 from
the channel 2 display and record onto the performance test record in
the “R-Channel” section.
To obtain values for marker 5, press Marker, MARKER 5, 20, x1, Sweep
Setup
, TRIGGER MENU, SINGLE.
17.Repeat step 15 and record the value on the performance test record
for marker 5.
In Case of Difficulty
1. If the analyzer fails the test at all power levels, be sure you followed
the recommended attenuator settings as listed in the performance
test record. Repeat this performance test.
2. If both port measured values are out of specification:
a. Recalibrate the power meter.
b. Repeat this performance test.
3. If the analyzer fails either Port 3 or Port 1 dynamic accuracy at lower
power levels:
a. Perform the IF amplifier correction constants and ADC offset
correction constants procedures in the standard documentation.
b. Repeat this performance test.
c. If it still fails, replace the A10 digital IF assembly.
d. Repeat the two adjustment procedures mentioned in the previous
step, then repeat this performance test.
