cPCI6U64-20AOF16C500KR

Overview

The General Standards cPCI6U64-20AOF16C500KR is a precision 20-Bit analog output product that provides 16 simultaneously clocked output channels in a 6U cPCI form factor. Outputs can be clocked at rates up to 500 KSPS per channel, and are supported by a 256K-Sample FIFO data buffer. Both continuous and burst clocking modes are supported, and voltage ranges are software-selectable as ±6V and ±3V, or optionally as ±10V and ±5V. Clocking and triggering rates can be derived from an internal rate generator, or from external clock and trigger sources to support the synchronous operation of multiple boards.

Specifications

Each analogue output channel of the General Standards CPCI6U64-20AOF16C500KR implements a weighted-DAC R-2R configuration, which minimizes latency and has no minimum clocking rate. An 8th-order lowpass reconstruction filter in each channel suppresses harmonics and undesirable artifacts in output functions. The outputs can be factory-configured for single-ended operation or for 3-wire differential operation.

On-demand autocalibration determines and applies error correction for all output channels. Eight bidirectional digital I/O lines are programmable as inputs or outputs.

This product complies with the IEEE PCI local bus specification Revision 2.3. System connections are made at the rear panel. Power requirements consist of +5 VDC in compliance with the PCI specification, and analog power voltages are generated internally. Operation over the specified temperature range is achieved with conventional air cooling.
