Making Adjustments

15. Frequency Response of the 8590L, 8591C, and 8591E

23.Adjust the frequency synthesizer AMPLITUDE for a MKR

amplitude reading of −14.00 dBm±.05 dB. Record the frequency

synthesizer AMPLITUDE setting here.

AMPLITUDE setting (4 MHz)____________________dBm

24.Subtract the frequency synthesizer AMPLITUDE setting (4 MHz)

recorded in step 23 from the frequency synthesizer AMPLITUDE

setting (41 MHz) recorded in step 20. Record the result as the

Amplitude Relative to 41 MHz here.

4 MHz Amplitude Relative to 41 MHz____________________dBm

25.Add the result from step 24 to the reading from step 10 and enter

that result in Column 2 of Table 2-6 (Option 001 only: Column 5) as

the 4 MHz error (relative to 300 MHz).

75 Ω input only: Starting with the error at 41 MHz, add Column 3

(System Error) to Column 2 (Error Relative to 300 MHz) and record

the result in Column 5 (Corrected Error Relative to 300 MHz).

Entering Flatness Correction Data

26.Enter the pass code by pressing the following analyzer keys.

PRESET

FREQUENCY, −2001, Hz

75 Ω input only: AMPLITUDE, More 1 of 2, AMPTD UNITS, dBm

27.To access the ﬂatness correction menu, press the following analyzer

keys.

CAL, More 1 of 4, More 2 of 4

SERVICE CAL

FLATNESS DATA

Perform the next step only if all the ﬂatness correction data must be

replaced in memory due to the repair or replacement of the A16

processor/video assembly.
