Probe Connectors.
The probe connectors are color-coded to match the labels on
the probes. Each probe connector accepts a 34-channel active probe consisting of
32 data channels and two clock/qualifier channels.
Probe Retainer Mounting Holes. The threaded probe retainer mounting holes
provide a means of securely holding the probes in place. You must tighten the
retaining screws to ensure a good ground connection for the probes to the
module.
Analog Outputs. Each TLA7Axx module has four analog output BNC connectors
regardless of the number of acquisition channels. The analog output connectors
allow you to tap into the analog signal of any channel and connect the signals to
an external instrument, such as an oscilloscope. This feature allows you to view
the analog component of a selected channels without requiring a separate
oscilloscope probe connection.
