Operation Manual

Grounding
The three waveform outputs (TRIGGER OUT, CLOCK & LOCK,
SYNC OUT) share the same ground. This ground should not
exceed ±20V Peak from chassis ground. If possible, this ground
should be connected to the chassis.
DFI and IEEE 488.2 share the same signal ground.

Input Power Requirements
Input power is connected to the SW 5550A, SW 3700A, or SW 1850A via the rear
panel connectors. See Table 2–7 and Table 2–8 for input current values.
WARNING!
An overcurrent protection device (i.e., circuit breaker) is required
in the building installation. The circuit breaker should be rated for
continuous current as required by the SW system (see Table 2–2).
Installation should comply with local safety standards.
A device to disconnect the SW system from the energy supply
source is also required. This switch or circuit breaker must be
close to the SW system, within easy reach of the operator, and
clearly labeled as the disconnection device for the SW system.
