HP 5355A - Special Functions

Model 5355A
Operation and Programming
Table 3-11. Diagnostic Modes and Special Functions
IN LOCAL operation the diagnostic modes listed below are obtained in numerical sequence by pressingthe gold MAN
FREQ and blue OFFSET FREQ keys simultaneously. Observe the display for the mode number listed below to determine
the diagnostic mode of the 5355A each time the keys are pressed. If diagnostic mode (1-10) is started in one column, the
sequence will stay in that column. Press reset on 5345A and set desired operational mode on 5355A to restart sequence.
In REMOTE operation, the diagnostic modes are programmed by use of the codes shown in Table 3-9 .
