Selectable Self

Tests

Seven self tests may be invoked individually via the Self Test menu. The seven

selectable self tests are:

Keyboard

RAM

ROM

Disk Drive

Cycle through all tests

The required test is selected by moving the cursor to the test and pressing the front

panel SELECT key. A pop-up menu appears with a description of the test to be

performed. The self test does not begin until the cursor is placed on Execute and

the front panel SELECT key is pressed.

After the test has been completed, either Passed, Failed, or Tested is displayed on

the Self Test menu in front of the test. These tests are used as troubleshooting

aids. Section 6 contains information on the individual tests used for

troubleshooting.

Performance

Test Interval

The calibration cycle for the logic analyzer is two years, therefore, periodic

performance verification of the HP 1650B/51B is recommended at two year

intervals. The instrument’s performance should be verified after it has been

serviced, or if improper operation is suspected. Calibration should be performed

before any performance verification tests. Further checks requiring access to the

interior of the instrument are included in the adjustment section, but are not

required for the performance verification.

Test Record The results of the performance tests may be tabulated on the Test Record

provided at the end of this section. The Test Record lists the performance tests

and provides an area to mark whether the pod passed or failed the test. The

results recorded in the table at incoming inspection may be used for later

comparisons of the tests during periodic maintenance, troubleshooting, and after

repairs or adjustments.
