Getting Started
The P6561A is a miniature, 200 MHz, 10X-attenuating passive probe
that is compatible with the TAS 485. It may also be used with
general purpose oscilloscopes having a 1 MW input impedance with
an input capacitance of 20 pF.
The P6561A is provided with several accessories designed to make
probing and measurement a simpler task. Please take a moment to
familiarize yourself with these accessories and their uses.
Figure 1 shows the probe and identifies various parts that are referred
to in these instructions.

Accessories and Operation
Ground lead with socket — Use the ground
lead to set a ground reference for your measurements. The ground lead socket (0.025 inch) can
be connected to the KlipChip test clip, directly
to a square-pin ground on a circuit board, or to
the right-angle square pin adapter.

Probe Tip
KlipChip
Ground Lead
To attach the ground lead with socket to the
probe, gently slide the probe boot back to expose
the metal sleeve. Then, slide the ground lead’s
metal ring over the probe tip onto the probe’s
metal sleeve. Push the boot back over the metal
sleeve and the metal ring. Align the boot slot to fit
over the contact of the ground lead.
Push-in probe tip — Use the push-in probe tip
when you are probing circuits by hand. The tip
presses into the socket in the probe head.
To attach the push-in probe tip, seat the tip into
the probe head and push the tip in until it is
seated; do not force the tip. To remove the tip,
gently grab the tip with small pliers and pull the tip
out.
KlipChip — Use a KlipChip test clip to access
fragile, dense circuitry. To connect a KlipChip,
insert the probe socket into its body.
You can connect a second KlipChip to the ground
lead with socket. To attach the ground lead, insert
the ground lead socket into the KlipChip body.
The KlipChip body freely turns, allowing better
probe orientation. To reduce stress and provide a
lower profile on components being tested, the
flexible sleeve of the KlipChip bends up to a 35
degree angle.
