Connecting Input Signals

G ro u n d in g
The most reliable signal measurements are made when the 2245A and the
unit under test are connected by a common reference (ground lead) in
addition to the single lead or probe. The ground lead of the probe provides
the best grounding method for signal interconnection and ensures the maxi­
mum amount of signal-lead shielding in the probe cable. A separate ground
lead (with a banana plug) can also be connected from the unit under test to
the 2245A ground jack on the front panel.
