The Keysight M9216A is a PXIe high-voltage data acquisition module engineered for fast parallel voltage measurements in automotive electronics and demanding test applications. It delivers 8 simultaneous acquisition channels with a built-in 32-to-8 multiplexer, expanding connectivity to 32 input ports. Each channel independently supports concurrent 5V and 100V measurement ranges, capturing signals across 1mV to 5V and 20mV to 100V without manual range switching. The 16-bit ADC provides precise positive voltage acquisition at 250 kS/s per channel with 85 kHz bandwidth, while semi-autonomous per-channel triggering enables flexible test sequencing. Designed for PXIe chassis integration, the module occupies two slots and routes all channels through an auxiliary output connector for downstream signal conditioning or analysis.
