Adjustments
Introduction
Introduction
This chapter provides adjustment procedures for the Agilent 86100A/B/C Infiniium DCA Main-
frame. Equipment required for individual adjustments is listed in the adjustment descriptions in
this chapter. Equipment satisfying the critical specifications listed may be substituted for the rec-
ommended model.
This chapter documents both manual and automated testing. The adjustments can be performed
either manually or with the VISION test system and the Agilent DSA Test Executive.
N O T E Do a Performance Verification before attempting any adjustments for customers requiring “As
Received” or “Pre Cal” data.
C A U T I O N Avoid damage to plug-in front panel connectors. Use 2.4 mm and 3.5 mm connector savers. These
connector savers are a supplied accessory. Minimize connector swapping during the procedures
to avoid connector wear. All connectors on test tools and adapters should be inspected both
visually and mechanically every few calibrations.
C A U T I O N All connectors should be clean and undamaged to ensure accurate measurements. All 2.4 mm and
3.5 mm connectors should be mechanically and visually checked before inserting any calibration
test tool into them. Damaged connectors or loose connectors may cause the performance
verification tests to fail.
C A U T I O N Avoid sharp bends in 2.4 mm, 3.5 mm, SMA, and optical cables. When mating 2.4 mm to 2.4 mm
or 3.5 mm to 3.5 mm, torque all connections to 8 in/lbs. When mating 3.5 mm to SMA or SMA
to SMA, torque all connections to 5 in/lbs.
C A U T I O N The module inputs are very sensitive to static discharge. Failure to observe proper antistatic
procedures may damage the gallium arsenide samplers. ESD damage is not covered under the
warranty. All maintenance or operation should be performed with an antistatic mat and wrist strap.
Refer to “Electrostatic Discharge Information” on page 1-8 for further information.
C A U T I O N Electrostatic discharge can seriously damage the module’s electrical inputs. To eliminate any
electrostatic build up from a cable you’re connecting to the module, connect a female short to
either end of the cable. Touch the short to an input connector hex nut on the module to discharge
any static build up to ground. Remove the short. Use this procedure for all cables before
connecting them to the module.
