Operating Basics
Product Description
This section provides a brief description of the P6419 logic analyzer probe,
instructions for attaching and using color-coded probe labels, and information
about connecting the probe from between the logic analyzer and your target
system.
The P6419 logic analyzer probe connects a Tektronix TLA520x mainframe,
TLA6xx mainframe, or a TLA7Lx/Mx/Nx/Px/Qx logic analyzer module to your
target system. The P6419 Probe is a high-density probe (see Figure 1) consisting
of a single independent probe head of 17 channel connectors each (16 data and
1 clock/qual).
Figure 1: P6419 logic analyzer probe
The following list details the capabilities and qualities of the P6419 Probe:
H Single-ended clock and qualification inputs
H Single-ended data inputs
H Compression contact (eliminates need for built-in connector)
H Land pattern (supports direct signal pass-through)
H Supports PCB thickness of 1.27 mm to 6.35 mm (0.050 in to 0.258 in)

Operating Basics
H Narrow 17-channel probe head (for easier placement and layout)
H 2X mode (for example, 1:2 demultiplexing) uses single-probe head
H Approximately 20% less channel density than current Mictor connectors
H Color-coded keyed signal connectors
H Adapter supports Mictor-based connections
H --3.5 V to +6.5 V input operating range
H --2.0 V to +4.5 V threshold range
H 500 mV minimum single-ended signal amplitude
H Minimal loading of < 0.7 pF @ 20 kΩ to ground loading

Operating Basics
This adapter supports standard Mictor connector footprints and signal connections on older logic analyzer designs.
The Mictor adapter adds 2.7 pF to the high-density compression probe load of
0.7 pF for a combined adapter and probe capacitance load of 3.4 pF.
See Figure 4 on page 4 for comparing the clearances between the P6434 and
compression probe adapters.

The Compression-on-PCB to P6434 Mictor adapter (see Figure 3) allows the
TLA520x mainframe, the TLA6xx mainframe, and TLA7Lx/Mx/Nx/Px/Qx logic
analyzer modules using a P6434 Probe to take advantage of the new compression
footprint and eliminate the need for Mictor connectors in your target system.
NOTE. To use the P6434 adapter, do not install press-in nuts. However, if board
thickness is > .093 in, you will need to install press-in nuts before migrating to
P6419 probes.
Two different screw lengths are required to accommodate the
1.27 mm to 6.35 mm (0.050 in to 0.250 in) PCB thickness range.
This adapter requires the use of the Compression-on-PCB to P6434 Mictor
adapter land footprint. See Figure 15 on page 33 for further information.
The Compression-on--PCB to Mictor adapter adds 1.5 pF to the P6434 probe
load of 2.0 pF for a combined adapter and probe capacitance load of 3.5 pF.

Attaching Probe Labels
When you purchase one or more P6419 logic analyzer probes with a TLA520x
logic analyzer mainframe or TLA7Nx/Px/Qx logic analyzer module, all labels
are already attached. If you purchase the probe seperately from the logic
analyzer, you must apply the color-coded labels as described in this section. The
labels help you identify the probe connections at the logic analyzer end and at
the target system end.
Table 1 lists the probe section and label color combinations. Refer to Table 1 and
to Figure 5 when you attach the probe labels.

P6419 Labels
Use the following instructions to attach probe labels to your Tektronix P 6419
Logic Analyzer Probe.
NOTE. Always use flat-nosed tweezers to remove the labels from the sheet of
labels. Never peel labels with your fingers. The labels ar e made of soft vinyl and
can stretch and distort easily. To avoid stretching the label, always grasp it from
the top right corner while removing it from the sheet of labels.
The adhesive on the vinyl labels is extremely strong. Carefully align each label
to the intended outline on the module end and probe head before attaching it to
the probe. Once labels are placed on the probe, they become very difficult to
remove.
You will be attaching labels to the module and and both sides of the probe head.
Refer to Figure 5 and use the following steps to attach the probe labels:
1. Identify the module end of the probe cable.
2. From the sheet of labels, locate the color-coded label for the module end of
the probe cable.
3. Attach the matching colored labels to the probe head on the other end of the
probe cable.
