Preventative Maintenance

Hardware Maintenance

The following procedures should be performed on a regular basis to

insure that your Test Set maintains optimum performance.

NOTE

Periodic Adjustment Interval

The adjustment programs Periodic Calibration, IQ Calibration, and

Eb/No Calibration should be performed after any assembly referred to

in Table 7-1 on page 159 is replaced, or at least every 24 months. These

program can be run anytime to optimize the performance of the Test

Set. See Chapter 7 , “Periodic Adjustments,” on page 157 for details.

NOTE

Performance Test Interval

The performance tests in Chapter 8 , “Performance Tests,” on page 173

should be performed when certain assemblies are repaired or replaced,

or at least every 24 months. See Table 3-2 on page 75 for those

assemblies requiring performance testing/calibration.

Adjustments

•Periodic Adjustments

Adjustments for calibration are part of the automated routines:

Periodic Calibration, IQ Calibration, and Eb/No Calibration. To run

these routines see “Running the Periodic, IQ, or Eb/No Calibration

Programs” on page 163. Running these routines will adjust internal

calibration and circuit paths for optimum performance. These

routines can be run on any interval from six months to two years,

depending on the severity of the application environment. These

routines should also be run whenever a significant change to

instrument’s hardware configuration is made. For instructions on

running the periodic adjustment routines see Chapter 7 , “Periodic

Adjustments,” on page 157.
