SCOPE
PROBE
1. The mercury wetted relay provides a high speed repeated
pulse to the D.U.T.
2. 100x scope probes are used, to allow high speeds and
voltages.
3. The worst-case condition for static dv/dt is established by
triggering the D.U.T. with a normal LED input current, then
removing the current. The variable RTEST allows the dv/dt
to be gradually increased until the D.U.T. continues to
trigger in response to the applied voltage pulse, even
after the LED current has been removed. The dv/dt is
then decreased until the D.U.T. stops triggering. τRC is
measured at this point and recorded.

Note: This optoisolator should not be used to drive a load directly.
It is intended to be a trigger device only.
