Installation
Strobe Signal
You can input one strobe signal in addition to the four event signals. The strobe signal controls the timing of reading the event
signals.
When Strobe is set to Off, the instrument reads the event signals at the timing of every two internal clock cycles, and updates
the event value if a state transition in the event signals are found.
When Strobe is set to On, the instrument reads the event signals when the strobe signal goes to low state (Enable), and
updates the event value if a state transition in the event signals are found.
NOTE. You cannot toggle the Strobe signal on and off using the screen interface or remote commands. The Strobe definition in
the sequence file can control the strobe signal input. For more information about Strobe Signal and Sequence file, refer to
the user online help.
