To Probe Single-Ended Signals with a Differential Head

Using a differential probe head rather than a single-ended probe head to probe
single-ended signals results in the advantages of higher bandwidth and increased
accuracy. Also no offset range is sacrificed when using a differential probe head,
as any supplied offset is applied only to the probe head's plus side. To learn more
about applying a DC offset when probing, refer to
Large DC Level"
If possible, orient the probe head vertically as shown in
probe head flat over a single-ended signal will cause coupling to the tip that can
degrade the performance. Notice that the head's "–" lead is connected to ground.
