VXI VX1410A, VX1420A Status and Events

Status and Events

The IntelliFrame Mainframe complies with SCPI version 1995.0. You can use the SYSTem:VERSion? command to read the latest version or the *IDN? command to read a more detailed identification message.

The IntelliFrame Mainframe supports the Status Byte model shown in Figure 3±11. The figure shows the core of the SCPI-required status reporting capability.

The status registers fit into a 16-bit integer with the most-significant bit always zero (positive logic). Unused or ªdon't careº bits in masks and registers always return zeros when queried.

The Operation Status register and the Questionable Status register outputs are logically ORed together as shown in Figure 3±11.

The Operation Status register contains information on the normal operation of the IntelliFrame Mainframe In particular, bit 8 contains summary information on the VXI Monitor status register (see Figure 3±12). The VXI Monitor Status register monitors activity on bits 0 through 3.
