Sequences For Mechanical Adjustments - Agilent Technologies 8753ES Option 011 Service Manual

Sequences for Mechanical Adjustments

The network analyzer has the capability of automating tasks through a sequencing
function. The following adjustment sequences are available from the Agilent Technologies
web site on the World Wide Web.
• Fractional-N Frequency Range Adjustment (FNADJ and FNCHK)
• High/Low Band Transition Adjustment (HBLBADJ)
• Fractional-N Spur Avoidance and FM Sideband Adjustment (APIADJ)
To download these adjustment sequences from the Internet:
Go the Agilent Technologies Website at the following URL:
Using the search function, search on the following phrase:
How to Load Sequences from Disk
1. Place the sequence disk in the analyzer disk drive.
2. Press
Local SYSTEM CONTROLLER
LOAD SEQ FROM DISK
3. Select any or all of the following sequence files by pressing:
• Select
LOAD SEQ APIADJ
Avoidance and FM Sideband Adjustment."
• Select
LOAD SEQ HBLBADJ
Transition Adjustment."
• Select
LOAD SEQ FNADJ
the "Fractional-N Frequency Range Adjustment."
How to Set Up the Fractional-N Frequency Range Adjustment
1. Remove the right-rear bumpers and right side cover. This exposes the adjustment
location in the sheet metal.
2. Press
SEQUENCE X FNADJ
Preset
3. Adjust the "FN VCO TUNE" with a non-metallic tool so that the channel 1 marker is as
many divisions above the reference line as the channel 2 marker is below it.
4. Press
SEQUENCE X FNCHK
Preset
• If the marker value is <7, you have completed this procedure.
• If the marker value is >7, readjust "FN VCO TUNE" to 7. Then repeat steps 2, 3, and
4 to confirm that the channel 1 and channel 2 markers are still above and below the
reference line respectively.
