The Keysight M9217A is a PXIe isolated digitizer module that delivers simultaneous high-resolution voltage acquisition across two independent channels within automated test systems. Each channel features a dedicated 16-bit ADC, enabling true parallel sampling without cross-talk or signal degradation. The module accepts input voltages up to ±256 V across a fully configurable range (±250 mV to ±256 V), eliminating the need for external signal conditioning in high-voltage applications. Built-in peak voltage protection rated to 400 V safeguards measurement integrity during transient events. A floating differential measurement capability of ±40 V extends measurement flexibility for multi-point acquisitions.
