» Functional Description
The PCI-180X series is a family of high performance data acquisition board for PC with PCI bus.
It features a continuous, 330KHz, gap-free data acquisition under DOS and Windows.
This family has the same architecture : one 12-bit 330KHz A/D converter, two 12-bit independent D/A converters, 16-channel digital input and 16-channel digital output.
The PCI-1800H/L provides 16-channel single-ended or 8-channel differential analog input.
The PCI-1802H/L provides 32 channel single-ended or 16-channel differential analog input.
The -H means high gain mode and the -L means low gain mode.
Two DACs of the multifunction card are independent bipolar voltage output with jumper selectable voltage output range.
The scan function of PCI-180X is so amazing. We call it "MAGIC SCAN".
It scans with two modes: "Fix channel scan" and "Variable channel scan".
The "Magic scan" mechanism not only scan the different input channels at vastly different rates, but also at different gain.
Even in multi-channel scan, both modes can be up to 330K samples per second.
The PCI-180X series also has other outstanding features. For example :
1. The data transfer rate of digital I/O is up to 2.1 M words/second (non-burst mode).
2. The throughput of D/A is up to 2.1MHz throughput max.
3. Provides three flexible external trigger modes, such as post-trigger, pre-trigger, middle trigger.
4. Provides M-function and Continue Capture function.
The PCI-1202H/L is very similar to PCI-1802H/L. The different items between the PCI-1802 and PCI-1202 are given as follows :
● A/D sampling rate is 110K samples/second for PCI- 1202.
● FIFOs size is 2K words for PCI-1202. The PCI-1602 is very similar to PCI-1802L.
The channelsdifferent items between the PCI-1802 and PCI-1602 aregiven as follows :
● 16-bit A/D converter
● A/D sampling rate is 200K sample/second for PCI- 1602F.
● A/D sampling rate is 100K sample/second for PCI- 1602.
» Applications
● High speed data acquisition system
● Process monitor and control
● Vibration analysis
● Digital pattern generator from digital I/O port
● Continue data capture
» "MAGIC SCAN" Function
The "MAGIC SCAN "controller is a innovative design. It has the following features :
1. Different gain for each scan channel
2. Non-sequential order for channel scan
3. Different sampling rate for each scan channel
4. Programmable different digital filter for each scan channel
5. Programmable high/ low alarm function, provide four different alarm monitor mode for each scan channel
6. The scan sampling rate can maintain at max. sampling rates without sacrifice the speed
7. Provide three external trigger: Pre-trigger, Post-rigger, Middle-trigger
8. Easy programming
The PCI-1800 can measure the high frequency signal and low frequency signal with different sampling rate.
In other words, the user doesn't have to waste valuable data memory for low speed channel.
It can measure small signal and large signal at the same time.
The digital filter can filter out some noisy signal.
The programmable high/ low alarm function will be very helpful for some monitor application system.

» Alarm type
» M_Function
M_Function is used to support simultaneous gap-free A/D, D/A at full-rated throughput.
The user can use the D/A channel to send out the pre-defined signal pattern to the external device and measure the output signal simultaneously.
The M_Function can be executed under DOS, Windows and Linux. Some programming language (VC/C++, BC++, VB, Delphi), Java and package (LabVIEW) can call the M_Function.
» Continue Capture Function
The PCI-180X/1602/1202 provide different continuously capture functions.
1. Continuous Capture at Low speed. The acquired data can be display at the monitor simultaneously.
No storage is required. Therefore the user can monitor the data continually.
2. Continuous Capture at high speed. The acquired data should be saved into the DRAM of PC. The capture period should be limited to the Memory size.
3. Continuous Capture at high speed. The acquired data should be saved into the SRAM card of PC.
The capture period should be limited to the Memory size.
The user should have to calculate the memory size according to the sampling rate and the capture period.
The Continue Capture function can be executed under DOS, Windows and Linux.
Continuous Capture function can support multiple boards.
» FIFO Size
How many FIFOs is large enough for your application? It depends on your application.
You can calculate the time buffer using the following formula.
For example, the FIFO size of PCI-1800 is 2 K words. The maximum.
Sampling rate of the board is 330KS/s .
The time buffer you can get is 1sec / 330K x 2K (FIFO SIZE) / 2 =3.1 ms.
It is enough for regular application under the DOS.
For some complicated multi-tasking applications, the user have to know the FIFO size he needs; otherwise the data might be lost.
The PCI-1800 series provide the possibility to upgrade the FIFO size.
» Diverse Trigger Mode
PCI-180X series provide diverse internal and external trigger modes.
The internal trigger includes software trigger and pacer timer trigger.
The external trigger includes the following trigger modes.
● Post-trigger mode : Acquisition begins after an external trigger and continues until the specified number of samples are collected.
● Pre-trigger mode : Acquisition occurs before an external trigger occurs.
● Middle-trigger mode : Acquisition occurs before and after an external trigger occurs. The samples number can be pre-defined.
