Installing the PCIM-DAS16JR/16

After you configure the board's switches and jumpers, install the PCIM-DAS16JR/16 into your computer. To
install your board, follow the steps below:

Install the MCC DAQ software before you install your board

The driver needed to run your board is installed with the MCC DAQ software. Therefore, you need to install the
MCC DAQ software before you install your board. Refer to the Quick Start Guide for instructions on installing
the software.

Turn your computer off, open it up, and insert your board into any available PCI slot.

1.

Close your computer and turn it on.

2.

If you are using an operating system with support for plug-and-play (such as Windows 2000 or Windows
XP), a dialog box pops up as the system loads indicating that new hardware has been detected. If the
information file for this board is not already loaded onto your PC, you will be prompted for the disk
containing this file. The MCC DAQ software contains this file. If required, insert the Measurement
Computing Data Acquisition Software CD and click

3.

To test your installation and configure your board, run the InstaCal utility installed in the previous section.
Refer to the DAQ Software Quick Start that came with your board for information on how to initially set up
and load InstaCal.

OK.

Board configuration with InstaCal

If you change the board configuration with InstaCal, you may have to also physically change the setting of a
corresponding switch or jumper on the board. Refer to Default hardware configuration on page 2-2 for specific
jumper and switch information.

Allow your computer to warm up for at least 15 minutes before acquiring data. The high speed components
used on the board generate heat, and it takes this amount of time for a board to reach steady state if it has been
powered off for a significant amount of time.

Analog inputs

The analog input mode is switch-selectable for eight differential or 16 single-ended analog inputs. The board
offers a 100 kHz maximum sample rate in single and multi-channel scans at any gain setting. A 1024 sample
FIFO assures that data taken from the board is transferred into computer memory without the possibility of
missed samples. The board has a digital trigger input with software-selectable trigger edge.

Software selects the bipolar/unipolar input configuration and input range. lists the analog input ranges

Table 4-1

and resolutions for the available input configurations and gains.

Table 4-1. Input range and resolution

Bipolar Range Resolution Unipolar Range Resolution

±10 V 305 µV 0 to 10 V 153 µV

±5 V 153 µV 0 to 5 V 76.3 µV

±2.5 V 76.3 µV 0 to 2.5 V 38.1 µV

±1.25 V 38.1 µV 0 to 1.25 V 19.1 µV

Burst mode

Channel-to-channel skew results from multiplexing the A/D inputs. Channel skew is defined as the time
between consecutive samples. For example, if four channels are sampled at a rate of 1 kHz per channel, the
channel skew is 250 µs (1 ms/4).

Burst mode minimizes channel-to-channel skew by clocking the A/D at the maximum rate between successive
channels. At the 1-ms pulse, channel 0 is sampled. After 10 µs, channel 1 is sampled. Channel 2 is sampled 10
µs after channel 1 is sampled. Channel 3 is sampled 10 µs after channel 2 is sampled. No samples are then taken
until the next 1-ms pulse, when channel 0 is sampled again. In this mode, the rate for all channels is 1 kHz, but
the channel-to-channel skew (delay) is now 10 µs. The minimum burst mode skew/delay on this board is 10 µs
(refer to ). Figure 4-2

Calibrating the PCIM-DAS16JR/16

The PCIM-DAS16JR/16 is shipped fully calibrated from the factory. For normal environments, you should
calibrate your PCIM-DAS16JR/16 board using InstaCal's calibration procedures every six months-to-a year. If
frequent variations in temperature or humidity are common, recalibrate at least every three months. It requires
less than 20 minutes to calibrate the board using InstaCal.

Calibrating the A/D and D/A converters

InstaCal provides step-by-step on-screen instructions to guide you in calibrating your board. You calibrate the
board's A/D converters by applying a known voltage to an analog input channel and adjusting the board’s trim
pots for offset and gain.

Calibrate the PCIM-DAS16JR/16 for the range you intend to use it in. Slight variations in zero and full scale
may result when the range is changed. These variations can be measured and removed in software, if necessary.

Required equipment

To calibrate the PCIM-DAS16JR/16, you need a precision voltage source, or a non-precision source and a 5½
digit digital voltmeter and a few pieces of wire. Use a jeweler’s screwdriver to adjust the trim pots. An extender
card is not required to calibrate the board.

Accuracy

Typical accuracy ±2.3 LSB
Absolute accuracy ±5.0 LSB
Accuracy components
Gain Error Trimmable by potentiometer to 0
Offset Error Trimmable by potentiometer to 0

PGA linearity error ±1.3 LSB typ., ±10.0 LSB max.

Integral Linearity Error ±0.5 LSB typ., ±3.0 LSB max.

Differential Linearity Error ±0.5 LSB typ., ±2.0 LSB max.

Each PCIM-DAS16JR/16 is tested at the factory to ensure the board’s overall accuracy error 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 are at their maximum level, and
causing error in the same direction.

Analog Input Zero drift Overall Analog Input drift

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 are at their
maximum level, and are causing error in the same direction.

Noise performance

The following table summarizes the worst case noise performance for the PCIM-DAS16JR/16. Noise
distribution is determined by gathering 50000 samples with inputs tied to ground at the PCIM-DAS16JR/16
main connector. Data represents both single-ended and differential modes of operation.
