*) Note: Feeding in the external trigger signal via the BNC connector EXT TRIGGER is equivalent.
Both input connectors must not be used simultaneously, because this can cause malfunctions of the
analyzer.
Important note:
Use only well shielded cables or disconnect the input pins of the USER CONTROL
connector in order to avoid spurious input signals which may cause undesirable events.
This is of particular importance for the external trigger input (pin no. 2) if the EXT
TRIGGER input is used.
