Function Output
The three output types are connected in parallel. There are three separate sets of output
connectors: BNC, XLR and banana plugs. The different output signals are the positive
output, negative output, common and chassis ground. The connectors are configured as
listed below.

The positive and negative outputs are both referenced to the common, which may be
floated +/-40 V
DC
from the chassis ground. The output impedance of the outputs is
selectable. If the output is terminated into an incorrect impedance the output amplitude
will be incorrect and may exhibit increased distortion.
Sync Output BNC
This output is a squarewave synchronized to the main function output. Its shield is
connected to chassis ground and cannot be floated.
Trigger / Gate In BNC
A low to high TTL signal on this input begins externally triggered bursts and sweeps.
For gated output, a TTL high gates the output on and a TTL low gates the output off. The
BNC shield is connected to chassis ground and cannot be floated.
