# Introduction

The ADLINK PCI/PXI-9816/9826/9846 are 10 MS/s, 20 MS/s, 40 MS/s sampling 16-bit 4-CH digitizers designed for digitizing high frequency and wide dynamic range signals with an input frequency up to 20 MHz. The analog input range can be programmed via software to ±1 V / ±0.2 V or ±5 V / ±1 V, based on the model. With a deep onboard acquisition memory up to 512 MB, the PXI/PCI-9816/9826/9846 are not limited by the data transfer rate of the PCI bus to enable the recording of waveforms for extended periods of time.

The PXI/PCI-9816/9826/9846 are equipped with four high linearity 16-bit A/D converters ideal for demanding applications with a high dynamic range such as radar, ultrasound, and software-defined radio.
