You can inhibit measurements by applying an external signal to the inhibit signal input
terminal. This is possible even while the gate is open or during measurement after
arming activation. You can also select which polarity of the signal, positive or negative, is
used to inhibit measurements. The relation between the inhibit signal, gating, and
arming for pulse width jitter measurement is indicated below.
