Power Reference Level Adjustment

Equipment

As per the test equipment list for the

Test method

1 Set: Coarse = 834, Fine = 550
2 Measure the power ref. level as per the performance test:
3 Repeat
4 Measure power ref. level as per the performance test:
5 Repeat
6 The adjustment is completed.
– This adjustment can be performed manually via the commands:
NOTE
– COARSE and FINE values are valid in the range of 0 to 1023
– If adjustment is not possible, then a fault may be present in the DUT (see
Keysight N8262A Service Guide
a If the result is >1 mW, then increment COARSE by 1.
b If the result is <1 mW, then decrement COARSE by 1.
step 2 until the result crosses the 1 mW boundary (in either direction).
a If the result is >1 mW, then decrement FINE by 1.
b If the result is <1 mW, then increment FINE by 1.
step 4 until the result crosses the 1 mW boundary (in either direction).
