Overview

These instructions apply to the following kits:

Description

The Socket Cables and Solder Tips allow you
to create custom
from your circuit to Tektronix P7500 Series
TriMode probes
include small-diameter, pre-trimmed leads for
you to solder to
fine-pitch features. Sockets at the ends of the
cables allow yo
soldered-down tips at multiple test points.

The TriMode High Temp Solder Tip and
TriMode Micro-Coax Solder Tip support full
TriMode capability (differential, single-ended,
and common-mode configurations). The
Damped Wire Pair are designed for differential
measurements only.

The Socket Cable XL is 5 feet long and is
intended for use only with the TriMode High
Temp Solder Tip. Always use the DSP filter files
when using the XL cable.

Using the Solder Tips

General recommendations:

Use the Damped Wires only in pairs, in the
A-B (differe

The solder tips cannot support the w eight of
the attached probe, so you must secure the
probe to the circuit board to relieve strain on
the tips and the solder connections.

Use a flux pen to add flux to the solder tips
and to your test points. The flux makes
soldering easier.

Use only ESD-approved soldering irons and
no-clean flux solder when soldering.

Procedure

1. Choose a location where the solder tip leads
can reach your test points, while keeping
the tip leads as short as possible for the best
signal quality. Note signal polarities and
grounds where applicable.

2. Apply solder to the test points on your
circuit.

3. Solder the tip leads to the test points on your
circuit and clip off any excess.

4. Connect the pins of the tip to the sockets
in the cable
grounds where applicable.

5. Align the cable with the red band to the A
input of the probe. Push the cable end into
the probe head until it seats in the head.

6. For a secure mechanical connection, use

sided tape or hot glue to secure the

double­tip to your circuit.

Signal Quality with the Socket Cable XL

Due to the length of the Socket Cable XL, the
input signal to the oscilloscope requires some
DSP filtering. You must load filter files onto your
oscilloscope from the CD that is included in your
XL cable kit. Always use the filter files when
you use the Socket Cable XL.

Load the Filter S

oftware

1. Insert the CD in the oscilloscope drive.

2. Navigate to the CD folder and make a copy

of the Socket Cable XL Filter Files.

3. Paste the files in C:/TekScope/
Math_Arbitrary_Filters/Probe-Filters.

4. From the Vertic

al menu, click Probe Cal.

Under Probe Tip, select Other Tip.

5. From the Math menu, select Math Setup.

6. Click Editor and select Filter.

7. In the user-de

fined Arbitrary Filter area,

click the Load button.

8. Navigate to the directory that you stored the
filter in (from step 2) and select the filter.

Using the Filter Software

Two filters are available:

XL_HTT_DIFF_Multirate.flt
(for differential mode)

XL_HTT_A_B_COMM_Multirate.flt
(for A-Gnd, B

-Gnd, and CM modes)

Both filters are multi-rate filters that can
operate at sampling rates from 50 GS/s down
to 1.25 GS/s. Since these are multi-rate filters,
the filter bandwidth and rise time vary with the
sample rate.

The filters are 4000 points long, so your
oscilloscope record length must be at least 2X
or greater to display a usable waveform. The
first and last 2000 points of record length are
truncated from the filtered waveform.

More information about using fi lters is located in
the Tektroni

x Digital Oscilloscopes Online Help
in the “Math Equation Editor (Filter Tab)” topic.
For specific

information on arbitrary filters, refer

to “Arbitrary filters, math”.

Replacing t

he Resistors

The resistors that are presoldered to the solder
tips need to

be replaced periodically, due to
normal wear. A kit of replacement resistors is
available (

order part number 020-2937-00).

1. Apply a soldering iron to the via on the tip

board and remove the existing wire. Work
quickly with a low-heat soldering iron.

If a small piece of wire is in the via, heat the
solder and use another piece of wire to push
the wire fragment from the via.

2. Add fresh solder to the via, if necessary.

3. Cut one lead of the resistor to 0.2" (5mm).

4. Heat the solder in the via and thread the cut

resistor lead into the via, leaving enough
lead length to bend the resistor flat with the
tip board.

5. Cut excess lead on the bottom of the board.

6. Cut the remaining resistor lead as necessary

to reach your test point.
