Agilent Technologies E1563A, E1564A Adjustment Procedures

164 Digitizers Adjustments Appendix E

Adjustment Procedures

WARNING Do not perform any of the following adjustments unless you

are a qualified, service-trained technician, and have read

the WARNINGS and CAUTIONS in this manual. Adjustment

procedures should be performed in the order shown in

this manual.

Adjustment

Conditions

See Table D-1, Recommended Test Equipment, for test equipment

requirements. For optimum performance, all adjustment procedures should

comply with following test conditions:

• Ambient temperature of the test area is between 18°C and 28°C

and stable to within ±1oC.

• Ambient relative humidity of the test area is <80%.

• Must have a one hour warm-up with all input signals removed.

• Shielded twisted Teflonâ insulated cable or other high impedance,

low dielectric absorption cable is recommended for all

measurements.

• Keep cables as short as possible. Long test leads can act as an

antenna causing pick-up of ac signals and contributing to

measurement errors.

General Procedure Follow each adjustment by a performance verification test for added

confidence. We recommend the following general procedure.

1. Perform the Zero Adjustment Procedure

2. Perform the Gain Adjustment Procedure(s)

3. Perform the Performance Verification Tests.

CAUTION ORDER OF ADJUSTMENTS REQUIREMENT. Range adjustments

MUST be performed in the order given in the adjustment table. An

accurate range adjustment requires the range adjustments prior to

the one in progress be within specification.

CAUTION ZERO ADJUSTMENT REQUIREMENT. The zero adjustment must

be a recent adjustment prior to performing the gain adjustments. It

is recommended you perform the zero adjustment one time just

before performing the gain adjustments.
