• Eight discrete channels with programmable sampling that provide a 24- bit DAC stage for each channel offers the user versatile and convenient digital to analog conversion.
• Outputs synchronized to the front panel external clock allow for multi-card synchronicity.
• Designed for Real Time Operating Systems (RTOS) to provide minimal pipeline delay (less than 5 microseconds). i.e. Linux or Vx Works.
• Interrupt free operation provides glitch energy of <5nV-sec and extremely low noise density (ï100nV/Hz).
• VME backplane is galvanically isolated from the analog section to reduce system integration problems.
VM8DAC VMEbus digital to analog converter (DAC) boards from Frequency Devices Inc. offer eight channels of precision low distortion/low noise, digital to analog converters that operate with a sample clock frequency derived from a master external clock and a programmable time base divider. The boards are available in a single width B-size (6U) VME form factor that conforms to VMEbus Revision C.1 as an A32/D32 Data Transfer Bus Slave.
VM8DAC boards provide high (24-bit) and low (16-bit) resolution data access to on-board DAC's. The boards interpret the received parallel data from the VM8DAC VMEbus as binary-2's complement. This data is serialized and transferred to any selected DAC channel at a fixed master time base where it is converted to analog signals at a software programmable sampling rate. The DAC channels may be configured to 16,384, 8,192, 4,096, or 2,048 samples per second.
