VXI 16-Bit ADC Scanning Module

The V213 is a single-width, C-size, register-based, VXIbus module that can digitize as many as 64 analog voltage channels. The resulting digital data is stored in a block of memory that can be read over the VXIbus.

The 16-bit ADC scans each channel at a scan rate chosen by the user. The number of channels and the scan rate are software selectable. Scans may be triggered from either an internal clock, one of the eight backplane TTL trigger lines, an external SMB connector on the front panel, or as a single scan.

The internal scan rate is divided into one part in 65,536, providing scan rates of 0.76 SPS through 20 KSPS (50 KSPS at lower gains). If single-scan operation is chosen, an interrupt may be generated at the end of the scan.

The V213 has programmable gain which can be set on a channel-by-channel basis. Gains of 1, 2, 5, 10, 20, 50, 100, 200, 500, 1000, and 2000 are available. On-board calibration is available on each channel for end-to-end calibration. A block of dual-ported memory is used to receive data from the ADC. The memory is divided into two blocks: "ping" and "pong". The ADC fills one memory block while VXIbus has access to the other. Using a ping/pong scheme provides random access to each channel's data. A 4 MB multibuffer memory option is available for higher data transfer rates.

The V213-AAA1 option provides a fixed, 2-pole, passive, 10 Hz filter at the input of every channel. Other filter options are available in a 1, 2, 5 progression from 10 Hz to 1 kHz. Under software control, channels 1 and 33 may be configured as isothermal reference channels for use with the KineticSystems Model V792 Isothermal Termination Panel.

The base option of the V213 provides 32 channels of analog input. Optional I/O expansion cards are available to provide an additional 32 channels of analog input, 32 channels of analog output, 64 channels of TTL I/O, and a combination of 16 channels of analog output and 32 channels of TTL I/O.

The RTD option provides 32 fixed current sources to be used with RTDs. A monitor channel is available to measure each current source. These monitor channels are in addition to the 32 channels on the base module and are configured as channels 33 through 64. The 32 channels on the base module are used to measure the voltages across the RTDs. This combination provides 32 RTD channels.

The V213 supports both static and dynamic configuration. It may be accessed using A32/A16, D32/D16 data transfers.
