HP 54201AID - Adjustments

SECTION 4

ADJUSTMENTS

This section contains front-panel calibration procedures and adjustment procedures for the
supply, display driver, analog board, and state trigger board. Table 4-1 lists the tabie of
Recommended Test Equipment.

4-2. CALIBRATION INTERVAL

There is no recommended calibration interval. Adjustment needs are defined by the pass/fail

status of resident self-tests and calibration routines. A failure of a SYSTEM menu self test should
be followed by resident SYSTEM menu calibration routines 0, 5, and 6 (in this order). The self tests
should then be re-selected to check whether the self-calibration routines corrected the error.

Repeated failure of a self-test, or failure of a self-calibration routine may dictate the need of a

particular hardware adjustment. Refer to table
Certain adjustments should be checked after a repair has been made. Refer to table

adjustments needed for a particular board repair. Performance tests that may be affected by these
adjustments are also listed in table

Always end the adjustment session with SYSTEM menu calibration routines 0, 5, and 6 (in this
order), and then perform the SYSTEM menu self tests to assure proper operation of the HP
54201A/D. Although self tests check for correct functional operation, they do not serve as a

performance verification. Persistent failure of one of the self tests is an indication of a faulty board;
refer to the troubleshooting procedures in this manual.

4-4. SYSTEM Calibration Menu

Front.panel calibration allows the user to execute automatic gain, offset, trigger hysteresis, trigger

calibration factors from inadvertent changes. This CAL switch must be set to the UNPROTECTED
position before executing automatic calibration. Error message "Cal RAM Write Protected" will be
displayed if calibration is attempted with the switch in the protected position.

Calibration 0 calibrates gain, offset, trigger hysteresis, and trigger level for Channel 1 and Channel
2 and takes about
may be executed by choosing 1 or 2 which takes about 1 1/2 minutes each to execute.
Calibration 3 selects trigger hysteresis
seconds each to execute. Calibration 5 and 6 calibrate delay for channel 1 and channel 2 and also
take about 15 seconds to execute. Calibration 7, 8, and 9 set service default calibration factors
and execution is immediate. A normal calibration would require calibrations 0, 5, and 6 (in this
order) to be executed. Calibrations 7, 8, and 9 are used for service setup and would be used after
a major repair to the instrument for initial setup procedures.

To execute the calibration routines, press the SYSTEM menu key, then press the NEXT/PREV key

until the Calibration menu is displayed as shown in figure 4-1. Move the blinking cursor to the
Execute Calibration field and enter the number of the routine you wish to execute. Follow the

instructions displayed on screen and watch the status line at the end of the calibration to see if the

instrument calibrated successfully. An audible beep will be heard when the selected calibration
routine is complete.

Execute Service routines 0, 1, and 2 (figure 4-2) provide

very

precise calibration of time and trigger
for the HP 54201A/D, and need only be performed in order to make highly accurate
measurements. These procedures are not a part of normal calibration and are not required for the
HP 54201A/D to function properly or to meet specifications. These routines should only be
performed after SYSTEM Calibrations routines 0, 5, and 6 (in this order) have been performed.
