described in detail below.

Adapter to Probe Head

1. Align the red and black inputs on the adapter
to those on the probe head.

2. Push the adapter into the probe head until it
seats against the probe head.

3. Use the 2 mm hex wrench to tighten the
screw on the adapter.

CAUTION. To prevent over-torquing the
screw, only insert the long end of the wrench
into the screw. The probe head can be
damaged by over-torquing the screw.

All of the adapters include these instructions and
a 2 mm hex wrench for securing the adapter to
the probe head. The P76TA adapter also includes
a kit of solder ramps to help minimize the solder
tip lead lengths for best performance.

P7500 Series Solder Tip Adapter

Description

The coax adapters are designed to complete
the connection from Tektronix P7630 probes to
SMP and SMA connectors on your circuit. The
coax adapters support full TriMode capability
(differential, single-ended, and common-mode
configurations).

Use the P76CA -292 Coax Adapter with high
bandwidth, low skew (<2 ps) cable pairs.
The cables should be short (<6 in) and have
high-quality connectors at both ends.

The P76TA S older Tip Adapter allows you to
connect to P7500 Series TriMode solder-down
tips; for example, the P75PST Performance
Solder Tip.

Using the Adapters

The probe and probe adapters are extremely
sensitive to electrostatic discharge (ESD).
Always work at an ESD-approved workstation or
in an ESD-approved environment.

Secure mechanical connections are necessary
to ensure the best signal integrity between the
adapters, the probe and the circuit under test.
Therefore, always observe the best practices
listed below for the best performance.

Use the 2 mm hex wrench included w ith the
adapters to tighten the screw on the adapter
housing to the probe head.

After you hand-tighten the coax connectors
to your circuit, use two wrenches to secure
each connector: One on the middle cable
nut to minimize cable twist, and a torque
wrench on the connector.

When you tighten cable connectors that are
close to each other (as on the P76CA-292
adapter), be careful not to strike adjacent
connectors with the wrench.

To preserve the adapter cables and maintain
the highest signal fidelity, never kink the
wires or put undue stress on them.

Secure the probe and probe adapter to the
circuit or chassis to prevent excessive strain
on the connections. For example, do not
let the w eight of the probe head pull on
the coax connectors if the probe is hanging
vertically off of the circuit.

Coax Adapters

To prevent damage and prolong connector and
cable life, the cable and center conductors must
not twist when making connections.

CAUTION. Always use a wrench to minimize
the cable twist when you connect and
disconnect the 2.92 adapters and cables. Use
a torque wrench to tighten the connectors to
8 in-lbs. Failure to do so will shorten the
service life of the adapters.

Coaxial cables can store a static charge when
they are not connected to equipment or circuitry,
so you should briefly short the cable center
conductor to the outer conductor before
connecting the cable to the adapters or your
circuit.

der Tips

1. Choose a location where the solder
tip can reach you

r test points, while
keeping the tip leads as short as possible
(<0.032 in./0.

8mm). Thesolderramps
included with the P76TA adapter help to
achieve this, a

3. Attach the solder ramp to the tip: Align the
bottom of the tip to the notch in the ramp
as shown, and then secure the tip to the
ramp with glue or tape. The notch in the
ramp helps you to position the tip as close
as possible to the circuit connections.

4. Slide the

tip over the soldered wires on your
circuit and solder the wires to the tip. Clip
off any ex

cess wires.

5. Secure the tip to your circuit with tape or
hot glue.

6. Align the solder tip cable with the red band
to the red A input of the probe adapter. Push
the cable into the probe adapter until it seats
in the adapter.

7. For a secure mechanical connection, use
tape or h

ot glue to secure the adapter and

probe head to your circuit.
