LeCroy Automotive Test Fixtures

LeCroy Automotive Test Fixtures (TF-AUTO-HMTD, TF-AUTO-MINI50, TF-AUTO-MATENET) are designed to simplify connection to automotive Ethernet interfaces for compliance testing and debug. These fixtures have very good RF characteristics and can be used for transmitter (Tx) testing according to the Open Alliance specification. Each fixture has one connector on the automotive side and two 3.5 mm SMA-compatible connectors on the instrument side.

Automotive Test Fixtures

TF-AUTO-HMTD TF-AUTO-MINI50 TF-AUTO-MATENET

While connector systems for Automotive Ethernet are not standardized, three connector types are used very often:

• HMTD from Rosenberger

• Mini50 from Molex

• MateNet from TE

TF-AUTO-HMTD, TF-AUTO-MINI50 and TF-AUTO-MATENET were developed to simplify connection to these interfaces

for automotive compliance testing and debug.

Connecting Fixtures

The fixtures have very good RF characteristics and can be used for transmitter (Tx) testing according to the Open

Alliance specification.

Each has one connector (m) on the automotive side and two, 3.5 mm SMA-compatible connectors (f) on the instrument

side. To avoid damaging the 3.5 mm connectors, use only high-quality cables with SMA, 3.5 mm or

2.92 mm connectors (m) to connect to the fixtures.

Note: The automotive connectors have a limited number of mating cycles. Therefore, they should be regularly

inspected and, if necessary, the entire adapter should be replaced. Contact Service for replacement.
