GE-VMIVME-4140 模拟输出板

 VMIVME-4140模拟输出板提供32个具有12位分辨率的高质量模拟输出通道，并且可以源或在+10 V时吸收10 mA。每个输出都有一个专用的D/a转换器（DAC）。模拟输出可以从用于线路测试的现场接线。校准和自检由VMEbus系统复位或执行软件命令启动。在校准期间，偏移和增益系数的表被编译并存储在RAM中。有一个偏移和增益条目对应于在六个输出电压范围的每一个中配置的32个通道中的每一个。

■单参考电位计-无需其他手动校准

■双缓冲输出的Sotware或外部同步更新

■随机更新（非扫描）

■0.8 0输出阻抗

■每个输出通道一个12位DAC

■离散导线或大量端接电缆

■32个模拟输出通道

The VMIVME-4140 analog output board provides 32 high-quality analog output channels with 12 bit resolution, and can source or absorb 10 mA at+10 V. Each output has a dedicated D/a converter (DAC). The analog output can be wired from the field for circuit testing. Calibration and self check are initiated by resetting the VMEbus system or executing software commands. During calibration, the table of offset and gain coefficients is compiled and stored in RAM. There is an offset and gain entry corresponding to each of the 32 channels configured in each of the six output voltage ranges.
