Model 5335A
Operation and Programming
NOTE
When STOP ARM is used the GATE MODE is usually used in
MIN. To aid the user in this condition the 5335A will auto¬
matically set the GATE MODE to MIN when the STOP ARM
is activated. However, the user can override this feature by
simply selecting any other GATE MODE after setting up the
ARMING modes.
3-92. When the GATE MODE is set to NORM, FAST, or MANUAL, and external arm is on,
the Gate Adj timer can be used to hold off the STOP ARM.
Example:
a. The rising edge of the ARM signal arms the START of the gate and starts the Gate
Adj timer (T).
b. The ARM signal is then ignored until the Gate Adj timer times out(T).
c. The next falling edge of the ARM signal ( 1$) t h e n arms the STOP.
In this way, multiples of the arm signal’s period can be used to arm the measurement.
