operation and Programming
3-31. Reading the convenience functions GATE TIME or TRIG LVL wiil not affect the
keyboard memory. Any changes to the key set-ups while in these functions will be carried
back to the set-up of the function that was active before. GATE TIME and TRIG LVL are not
affected by MATH and STATISTIC functions. For example:
1. Presently in FREQ A, we enter an OFFSET of 123.
2. We switch to PER A, where we see by the OFFSET key indicator, that the OFFSET is off.
3. Selecting FREQ A, we see that the OFFSET is again 123.
4. We then select TRIG LVL, and then GATE TIME.
5. While in GATE TIME we set the GATE MODE to FAST.
6. Returning to FREQ A, we still have an OFFSET 123, but also, the GATE MODE is now
in FAST.
7. We select PER A, then PULSE A. Now, when we return to FREQ A, all set-ups go to the
default positions.
3-32. Key Default
3-33. The initialized and/or default positions for all operator keys and controls are as follows:
Default

STATISTICS...OFF
RANGE HOLD .OFF
EXT ARM ENABLE .OFF
CYCLE .NORM
GATE MODE .NORM
GATE MODE .MIN
(for TIME, 1/TIME, RiSE/FALL,
SLEW, DUTY CYC, PHASE)

3-35. The front panel controls allow for a direct, key-per-function selection from 16 labeled
function operations. A sequence of keystrokes will allow the operator to enter a Special Function
Mode , in which the original 16 functions, plus 4 additional unlabeled functions and an extensive
diagnostic mode can be accessed. The four unlabeled “phantom" functions are:
FREQ B
PULSE B
TIME B—A
TOTALIZE A-B
3-36. The diagnostic mode allows the user considerable flexibility during troubleshooting
through a set of 33 discrete, self-diagnostic test routines. A more complete description of the
Special Function Mode and complete procedures using the diagnostic routines are provided
in Section VIII.
