Operating Basics
Product Description
The DAS Mass Termination Interface (MTIF) allows you to connect 100 logic
analyzer channels to a Tektronix Microprocessor Support (TMS) probe adapter or
directly to your system under test (SUT) in one fourth the physical area needed to
connect standard probes. The vertical clearance dimension is less than a half inch
when used with the Low-Profile Extender.
To connect directly to your SUT, you must include compatible Mictor connectors
in your circuit board design. To do this, be sure you understand the requirements
and conform to the guidelines in these instructions for designing an interface.
This section contains a product description and information on how to connect
the DAS MTIF to and disconnect it from a SUT.
The DAS MTIF has four parts: one DAS MTIF adapter and three DAS MTIF
probes. Connectors on one side of the adapter accommodate four 92AC96 cables.
The connectors on the other side of the adapter accommodate the probes.
One end of each probe is called the probe tip and connects to your SUT. The
other end is called the interface end. Figure 1 shows the DAS MTIF.

Operating Basics
Connecting the DAS MTIF to the SUT
Each DAS MTIF probe can connect to surface-mounted or straddle-mounted
Mictor connectors. You can use the Low-Profile Extender (available as an
optional accessory) to connect the probe to systems with as little as a half inch of
clearance between circuit boards. You can also install an optional latch housing
around the connector to provide positive retention of the probe.
In the following procedures, a surface-mounted Mictor connector is shown in the
figures. These procedures are the same for the straddle-mounted connector.
Direct Connection
To connect the DAS MTIF to a Mictor connector in your SUT (or on a TMS
probe adapter), follow these steps:
1. Line up the pin 1 indicator on the probe tip with pin 1 on the connector in
your SUT. The Mictor connector is keyed to prevent incorrect connections.
CAUTION. Incorrect handling of the probe while connecting it to the SUT can
result in damage to the DAS MTIF probe or to the mating connector in the SUT.
To avoid damaging the probe and SUT, always position the probe perpendicular
to the mating connector and gently connect the probe.
2. Position the probe tip perpendicular to the mating connector and gently
connect the probe as shown in Figure 2.
3. When connected, push down the latch releases on the probe to set the latch.

4. Line up the pin 1 indicator on the interface end with the pin 1 indicator on
the corresponding A, D or C probe connectors on the adapter.
5. Position the interface end perpendicular to the mating connector and gently
connect the end.
6. When connected, push down the latch releases on the probe to set the latch.
7. Connect the 92A96 cables. Match the label colors on the 92A96 cables to the
colors printed on the adapter. The cable connectors are keyed.
