PCI/PXI-9820
2-CH 65 MS/s 14-Bit Digitizers with SDRAM
Introduction
ADLINK’s PCI/PXI-9820 is a 65 MS/s, high-resolution PXI digitizer with deep SODIMM SDRAM memory. The device
features flexible input configurations, including programmable input ranges and user-configurable input impedance. With
the deep onboard acquisition memory, the PCI-9820/PXI-9820 is not limited by the 132 MB/s bandwidth of PCI bus and
can record the waveform for a long period of time. The PCI-9820/PXI-9820 is ideal for high-speed waveform capturing,
such as radar and ultrasound applications, as well as software radio applications, or those signal digitizing applications
which need deep memory for data storage.
PCI-9820
■ Analog Input
The PCI/PXI-9820 device features two analog input channels. The small signal bandwidth of each channel exceeds 30
MHz. The input ranges are programmable as either ±5 V or ±1 V. The 14-bit A/D resolution makes the PCI/PXI-9820
ideal both for time-domain and frequencydomain applications.
■ Acquisition System
ADLINK PCI/PXI-9820 device uses a pair of 65 MS/s, 14-bit pipeline ADCs to digitize the input signals, and the device
PXI-9820
provides an internal 60 MHz timebase for data acquisition. The maximum real-time sampling rate is 60 MS/s with internal
timebase, and is up to 65 MS/s with external timebase. By using a "ping pong" mode, the sampling rate is up to 120
MS/s with internal timebase or 130 MS/s with external timebase.

The PCI/PXI-9820 device features flexible triggering functionalities, such as analog and digital triggering. The analog
trigger features programmable trigger thresholds on rising or falling edges on both input channels. The 5 V/TTL digital
trigger comes from PXI trigger bus or the external SMB connector for synchronizing multiple devices.
Post-trigger, pre-trigger, delay-trigger and middletrigger modes are available to acquire data around the trigger event.
The PCI/PXI-9820 also features repeated trigger acquisition, so you can acquire data in multiple segments coming with
successive trigger events at extremely short rearming interval.

■ Calibration
The auto-calibration function of the PCI/PXI-9820 is
performed with trim DACs to calibrate the offset and gain
