kit shown in the illustration below.

Tektronix part number 020-2506-XX,
Resistor/Wire kit. The kit includes the
resistors and wire leads shown in the
preceding image.

Use the resistors with crimped-on 0.008-inch
diameter wire leads when you need to connect to
smaller-diameter vias on your circuit board.

Order the Resistor/Wire kit for replenishing
the resistors and wire from your
Solder-in Accessory kit.

Overview

The Solder-in Accessory kit allows you to
create a customized, hands-free connection from
your circuit to Tektronix model P73XX Series,
TDP3500, and TDP4000 differential probes.

The adapters use low-insertion force sockets that
provide a break-away feature to protect your
probe and circuitry from damage by excessive
forces on the probe cable.

The adapter easily connects and disconnects to
the probe head. You can connect several adapters
throughout your circuit to gain access to difficult
test points quickly and e asily.

The elastomeric contacts inside the adapter are
rated for 50-75 insertion cycles with the probe
tip. Replace the adapter after exceeding these
limits to avoid unreliable operation.

Using the accessory kit

Before you begin soldering accessory
components to your circuit, consider the
following points:

You can use this kit to browse your circuit
as well as creating a soldered connection.

The adapter-side of the resistor leads are
precut to ~0.110 inch so that the resistor
bodies touch the adapter sockets when fully
inserted.

Cut the circuit-side resistor leads as short as
possible, and keep the lengths matched for
best signal integrity. (See Table 1.)

The adapter cannot support the weight of
the attached probe. Therefore, before you
solder the resistors or wires to the circuit
board, position the adapter so that you
can secure the probe to the circuit board
to relieve strain on the adapter and solder
connections.

You can use 0.020-inch diameter pins or
wire instead of resistors, but do not insert
anything larger than a 0.022-inch diameter
pin into the adapter, or you will damage the
adapter.

Do not use this adapter for square pins.
Instead, use the square pin adapter,
Tektronix part number 016-1884-XX.

Do not solder the adapter directly.

To avoid damaging the probe, disconnect
the probe from the adapter before soldering
components.

Only use ESD-approved soldering irons
and no-clean flux solder when soldering
components to your circuit.

Procedure

Refer to the illustrations as you follow these steps:

1. Connect the resistors or wires to the adapter.
Push the resistors all the way into the
adapter sockets, so that the resistor bodies
touch the sockets.

2. Verify that both resistors or wires can reach
your test points, and that you can locate the
adapter in a secure position.

3. Cut the resistor or wire leads (as short as
possible and th
and solder them to the circuit.

4. When needed, use an adhesive such as
quick-set epoxy or hot glue, to secure the
resistors or wires to the circuit board.

5. Gently push the probe into the adapter until
it seats against the probe head.

6. Secure the probe to the circuit board with
tape or hook-a

e same length, see Table 1),

nd-loop strips.

Resistor and wir

e lead lengths

The resistors included with this kit have leads
that are precut t

o 0.110 inch on one side for
inserting into the adapter. This length ensures
good contact wi

th the adapter.

Cut the circuit-side of the resistors very short.
See Table 1 for typical electrical characteristics
of the adapter using various lead lengths and
resistor values.

Use Table 1 to help you select the component
configuration that optimizes response for
bandwidth, rise time, or overshoot, based on your
measurement needs.

If you use components not included with this
kit, keep the ci

rcuit-side lead lengths as short as

possible, and adapter-side lead lengths between

0.110 and 0.13

0 inches.
