EEPROM — checksum the EEPROM, which is used for non-volatile
memory.
HP-IB — test GPIB chip.
QSPI — test serial hardware control loops.
FPGA — internally measure the timebase to test count circuitry.
FR END — check front end circuits, either by swinging trigger levels
(during power-on test and ALL test) or asking you to connect
the timebase output to channel 1.
MEAS — make a measurement, either by swinging trigger levels (during
power on test and ALL test) or asking you to connect the
timebase output to channel 1.
INTERP — test interpolators.
KEYPAD — request user to press all keys. Note, this test is not available if
TEST LOOP: is ON. TEST LOOP: must be OFF.
PRINT — send three test lines to a printer via the RS-232. If in talk-only,
also send three test lines to a printer via the GPIB.
Example Procedure for Running the Self Test
1 Press and hold Recall (Utility) key, then cycle POWER key.
2 Press Recall (Utility) key until TEST: is displayed.
3 Press any one of the arrow keys to select the desired menu choice in the menu
item (for example, the ALL menu choice).
