The IP-AD-3216 has four CMOS analog multiplexers that are fault protected. Each multiplexer has 8 inputs and one common output. These outputs are acquired by a four input differential multiplexer.
The differential multiplexer inputs can then be configured for single-ended, differential modes, or calibration modes. These outputs then go to a PGA where the gain can be set for 1, 2, 4, and 8.
When the acquisition is started the two A/D converters acquire the data simultaneously from the multiplexers. The data is stored in a 16-bit FIFO in an interleave matter reading group #1 (odd channel) first then group #2 (even channel). Further acquisitions before the trigger will result in the earliest data being discarded, thus maintaining the most recent data in the FIFO.
Once the trigger event is seen, no more data is discarded from the FIFO, and the acquisition proceeds until the FIFO is full. At this point, the acquisition stops, and the HOST can read the data from the IP. Interrupts can be sent to the HOST at Event and at acquisition finished.
If desired, such as for a continuous acquisition, data can be read from the FIFO while acquisition is in progress, supporting continuous streaming.
Software Support
The IP-ADM-2100-32CH is supported under Windows NT/2000 by two sample programs, which are supplied with the IP in the board support package. Both examples are designed to work with an IP-type carrier from ALPHI, such as the PCI-4IPM.
One sample program, called SnapShot, fully exercises the IP module in pre- and post-trigger modes, and displays the data to the screen. Data can be stored to a file and can be reloaded in the program at a later time.
The second program, called DrawIpAdc, operates the IP in continuous mode, and displays the data to the screen.
Full source to both HOST DSP code and the applications are provided.
