Trigger Bus Connectors

The EX7000 provides an LXI compatible trigger bus connector set on the rear panel of the instrument. Both connectors have the same pin assignments and are wired in parallel. For more information on the LXI Trigger Bus and creating an appropriate cable, please visit www.lxistandard.org and refer to LXI Standard Revision 1.2 and LXI Trigger Bus Cable and Terminator Specifications Rev 1.1. The trigger bus pin assignments are provided on the next page.

Digital I/O Connector

The EX7000 features an 8-channel digital I/O port on the rear panel of the instrument. This port can be used as a trigger source and as a general purpose output device. The digital I/O connector is a standard DB-9 with the following pin assignment:

As a general purpose output device, each DIO channel can be independently programmed with regards to its output functionality and its static level to assume when enabled as an output. When not enabled as an output, a channel becomes tri-stated, preventing conflict with other potential voltage drivers. Reference the port’s electrical specifications in Table 3-1 for voltage tolerance limits and output drive capabilities. Regardless of output functionality, each channel provides constant input functionality. That is, the input level on each channel can be accessed without a specific enable command. Moreover, the base functionality of the DIO channels is not affected by triggering, scanning, or any other instrument process.
