The 14-Bit PCIe-14HSAI4 analog input board samples and digitizes as many as four analog input channels simultaneously at sustainable aggregate rates up to 100 million conversions per second. Each input channel implements a dedicated 14-Bit ADC for data conversion, and the resulting 14-bit sampled data is available to the PCI Express bus through a 1-MByte FIFO buffer. The sample clock can be generated from an internal rate generator or by external hardware, and multiple boards can be operated synchronously. Pretrigger and Sync-on-Level oscilloscope burst-triggering functions are supported. All operational parameters are software configurable.

Input ranges are software-selectable as ±2.5V, ±1.25V or ±0.625V for the standard Wideband input configuration. Input range options also include a High-Level configuration with selectable ranges of ±10V, ±5V or ±2.5V, and a Transformer-Coupled configuration with 2Vp-p and 1Vp-p ranges. Wideband and Hi-Level inputs are DC-coupled; Transformer-Coupled inputs are AC-coupled. The analog inputs can be jumper-configured as either differential or single-ended.

For the Wideband and High-Level input configurations, on-demand autocalibration determines offset and gain correction values for each input channel, and applies the corrections subsequently during acquisition. A selftest switching network routes calibration reference signals to each channel through internal selftest switches, and permits board integrity to be verified by the host.
