5-8-6 Probe Selection Board (T-PSB)
The Probe Selection Board (T-PSB) enables acquisition and processing of signals from and to probes
connected to the front panel.
The main purpose of the T-PSB is to select the active probe and transfer the probe data to the T-CFE
Board. The PSB provides a mechanical and electrical interface for 4 RS probes.
The T-PSB supports the following:
• Probes with up to 128 elements, directly.
• 192 element probes, using on-board HV multiplexers.
The PSB receives all the required control lines from the T- CFE board. The analog receive/ transmit lines
are routed to the T-CFE board using two dedicated connectors. A third connector is used for power and
control.
5-8-6-1 T-PSB Default Mode
After Venue™ system power-up, the T-PSB automatically enters default mode. In this mode, the
following states are applicable:
• No connector is selected.
• High voltage supplies to all probes are disconnected.
