Overview
The PCIe-DAS1602/16 is a multifunction measurement and control board
designed for the PCI Express (PCIe) bus.
The board provides 16 SE or eight DIFF
input channels with 16-bit resolution,
two 12-bit analog outputs, 32 DIO, and
three 16-bit counters.
The PCIe-DAS1602/16 is a fully connector- and software-compatible replacement for the Measurement Computing
PCIM-DAS1602/16.
The PCIe-DAS1602/16 provides 16 single-ended or eight differential analog inputs, sample
rates up to 100 kS/s, two 12-bit analog outputs, 32 digital I/O, and three 16-bit counters
Analog Output
Signal Connections
A 37-pin connector provides access to
the 16 SE/8 DIFF analog inputs, two
analog outputs, four digital and outputs,
and three counter/timer channels.
A 40-pin connector provides access to 24
DIO connections.
Analog Input
The PCIe-DAS1602/16 provides 16 SE
or eight DIFF analog inputs. The input
mode is switch-selectable to configure all
channels as either SE or DIFF.
The board offers bipolar analog input
ranges of ±10 V, ±5 V, ±2.5 V, and
±1.25 V, and unipolar ranges of 0 V to
10 V, 0 V to 5 V, 0 to 2.5 V, and 0 V to
1.25 V.
Input ranges are software-selectable, and
polarity is switch-selectable.
Sample Rate
The PCIe-DAS1602/16 offers a singlechannel sample rate of 100 kS/s divided
by the number of channels being
sampled.

Two 12-bit multiplying digital-to-analog
converters (DACs) provide analog output
on the PCIe-DAS1602/16. DAC0 and
DAC1 each accept a precision 5 V or
10 V reference, which provides onboard
D/A unipolar ranges of 0 V to 5 V and
0 V to 10 V, and bipolar ranges of ±5 V
and ±10 V.
Other ranges between 0 V and 10 V
are available when an external precision voltage reference is supplied to the
DAC0 REF IN pin or DAC1 REF IN pin of
the main connector.
Onboard reference voltage, user-supplied
reference voltage, and polarity are all
jumper-selectable.
Digital I/O
The 24 digital I/O connections available on the 40-pin DIO connector of the
PCIe-DAS1602/16 are available as two
eight-bit ports (ports A and B) and two
four-bit ports (ports CH and CL). Each
port can be configured independently
as either input or output. These ports
default to the input state (high impedance) on power up or reset.

Connect the counter clock to the onboard 10 MHz crystal
oscillator, or leave unconnected for user input.
The eight digital I/O connections available on the main 37-pin
connector consist of two 4-bit ports. One port is permanently
configured as input, and the other port is permanently configured as output.
The A/D pacer clock trigger edge (rising or falling) that initiates the A/D conversions is jumper-selectable on the PCIeDAS1602/16. The jumper is configured for rising edge by
default.
Pull-Up/Down Configuration
The PCIe-DAS1602/16 includes jumpers to set the digital
bits for pull-up (+5 V) or pull down (0 V) when the board is
powered on and reset. Ports A, B, CH, and CL are factory-configured for pull-up (+5 V).
Calibration
Counter/Timer I/O
Calibrating the PCIe-DAS1602/16 requires the following
equipment:
Each PCIe-DAS1602/16 offers three 16-bit down counters.
Each counter accepts frequency inputs up to 10 MHz, and
provides clock, gate, and output connections.
• a precision (or non-precision) voltage source
Field Calibration
• a 5½ digit digital voltmeter
• a few pieces of wire are required.
The frequency of the square wave used as a clock by the A/D
pacer circuitry is jumper-selectable for 1 MHz (default), or
10 MHz. The internal pacer output driving the A/D converter
is also available at pin 20 (CTR 3 Output) on the main 37-pin
I/O connector.

PCIe-DAS1602/16
Software
Calibrate the A/D converters by applying a known voltage to
an analog input channel and adjusting trim pots for offset
and gain. Three trim pots require adjustment to calibrate the
analog input section of the board. There are also three pots
associated with each of the analog output channels.
If frequent variations in temperature or humidity are common, recalibrate at least every three months.
Factory Calibration
PCIe-DAS1602/16 devices are factory-calibrated. Specifications
are guaranteed for one year. For calibration beyond one year,
return the device to the factory for recalibration.
Calibrate the PCIe-DAS1602/16 for the range you intend to
use it in. When the range is changed, slight variations in zero
and full scale may result. These variations can be measured
and removed in software if necessary.

Absolute error change per °C temperature change is a combination of the gain
and offset drift of many components. The theoretical worst case error of the
board may be calculated by summing these component errors. Worst case
error is realized only in the unlikely event that each of the component errors
is at their maximum level, and causes error in the same direction.
The following table summarizes the worst case noise performance for the
PCIe-DAS1602/16. Noise distribution is determined by gathering 50,000
samples with inputs tied to ground at the PCIe-DAS1602/16 main connector.
Data is for both SE and DIFF modes of operation.

Each PCIe-DAS1602/16 is tested at the factory to assure the overall error of
the board does not exceed ±5 LSB.
Total board error is a combination of gain, offset, differential linearity, and
integral linearity error. The theoretical absolute accuracy of the board may be
calculated by summing these component errors. Worst case error is realized
only in the unlikely event that each of the component errors is at their maximum level, and causes error in the same direction.
Input noise is assumed to be Gaussian. An RMS noise value from a Gaussian
distribution is calculated by dividing the peak-to-peak bin spread by 6.6.
Noise performance may be affected by input cabling and/or excessive noise
from adjacent PCBs within the PC enclosure.
Crosstalk is defined here as the influence of one channel upon another when
scanning two channels at the specified per channel rate for a total of 50,000
samples. A full-scale (FS) 100 Hz triangle wave is input on channel 1, with
channel 0 tied to analog ground at the 37 pin user connector. The table below
summarizes the influence of channel 1 on channel 0 and does not include the
effects of noise.
