Introduction
Acquisition Memory
ADLINK PCI-9820 is a 65 MS/s, high-resolution PCI
digitizer with deep SODIMM SDRAM memory. The
device features flexible input configurations,
including programmable input ranges and userselectable input impedance. With the deep on-board
acquisition memory, the PCI-9820 is not limited by
the PCI 132 MB/s bandwidth, and can record the
waveform for a long period of time. The PCI-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.
The PCI-9820 device supports different size of
SODIMM SDRAM ranging from 128 MB to 512 MB.
The digitized data are stored in the on-board
SDRAM before being transferred to the host
memory. The PCI-9820 device uses the scattergather bus mastering DMA to move data to the host
memory. If the data throughput from the PCI-9820 is
less than the available PCI bandwidth, the PCI-9820
also features on-board 3k-sample FIFO to achieve
real-time transfer bypassing the SDRAM, directly to
the host memory.
Analog Input
The PCI-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-9820 ideal both for timedomain and frequency-domain applications.
Acquisition System
ADLINK PCI-9820 device uses a pair of 65 MS/s,
14-bit pipeline ADCs to digitize the input signals, and
the device 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 the "ping
pong" mode, the sampling rate is up to 120 MS/s
with internal timebase or 130 MS/s with external
timebase.

Generation
Post-trigger, pre-trigger, delay-trigger and middletrigger modes are available to acquire data around
the trigger event. The PCI-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-9820 is
performed with trim DACs to calibrate the offset and
gain errors of the analog input channels. Once the
calibration process is done, the calibration constant
will be stored in EEPROM such that these values
can be loaded and used as needed by the board.
Because all the calibration is conducted
automatically by software commands, you don't have
to adjust trimpots to calibrate the boards.

Converter
On the PCI-9820, a synchronization bus (system
synchronization interface, SSI) routes timing and
trigger signals between one or more PCI-9820
devices. The SSI could reach synchronization
between different acquisition hardware by a common
trigger signal or a single sample clock for the
acquisition of multiple devices.
Triggering
The PCI-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
SSI interface or the external SMB connector for
synchronizing multiple devices.
