Vmic VMIVME-2540/VMIVME-2540-000 24-Channel Intelligent Counter

The VMIVME-2540 is used for buffer measurement and queue control commands. The measurement function is also supported in continuous measurement mode, where measurements can be repeated without the involvement of the host CPU. I/O connections are routed through high-density connectors located on the front panel, supporting differential and single-ended signal levels. The user data exchange interface for measurement and generation modes conforms to the ANSI/IEEE standard 754-1985 for 32-bit floating-point operations. The integer mode operates with double complement signed and unsigned arithmetic.
