Audio Precision ATS-1 Access User Manual

Often, the cables described above are not available, and
single-conductor shielded cable must be used. The shields of these
coaxial cables are susceptible to interference. You can often reduce this
interference, at the risk of introducing ground loop problems, by
grounding the shell of the BNC connectors on the connector panel and
using an unbalanced 50 Ω output configuration.
To do this, connect a short jumper from the banana plug connector for
the low side (which is the same point as the BNC shell) to the nearby
ground connector on the connector panel, as shown in Figure 3-16,
and select 50 Ω Unbal on the Generator panel. Note that you have to
do this for both channels if both are used.
The same situation exists for the input to the analyzer: the input to
each channel is balanced, and the BNC connector shell is floating. You
can ground the shell in the manner described above if desired.
