VMIVME-4140-001-VMIVME4140  模拟输出板  可以从现场接线断开用于离线测试

功能特征

VMIVME-4140模拟输出板

提供32个高质量的12位模拟输出通道

分辨率，并且可以在±10v下输入或吸收10ma。每一个输出有一个专用的D/ a转换器(DAC)分配给它。

VMIVME-4140-001-VMIVME4140模拟输出可以从现场接线断开用于离线测试。校准和自检由a启动

VMEbus系统复位或由某个软件执行命令。在校准过程中，一个偏移和增益表系数被编译并存储在RAM中。这里有一个入口对于对应于32个通道中的每一个的偏移和增益可配置6个输出电压范围。

自检:系统复位后自动进行自检。

VMIVME-4140-001-VMIVME4140自测寄存器指示成功或失败，并可以指示发生故障的通道。

前面板状态LED灯:a后点亮系统复位。指示灯熄灭完成自检和自动校准。LED也可以在软件控制下打开和关闭。VMEbus兼容性:地址修改位是跳线

选择并解码为支持非特权，监督，非特权人士或监事会成员。

输出数据传输:输出数据以32位16位存储寄存器。该板可以通过软件配置为接受两个的补码或偏移二进制数据。输出但是，更改可能由寄存器访问和输出发起双缓冲允许所有的通道由软件或外部同步更新触发器。

Functional characteristics

VMIVME-4140 analog output board

Provides 32 high quality 12-bit analog output channels

Resolution, and can input or absorb 10ma at ±10v. Each output has a dedicated D/ a converter (DAC) assigned to it.

VMIVME-4140-001-VMIVME4140 Analog output can be disconnected from field wiring for off-line testing. Calibration and self-test are initiated by a

The VMEbus system resets or a command is executed by some software. During calibration, an offset and gain table coefficient is compiled and stored in RAM. There is an entry that can be configured with 6 output voltage ranges for offset and gain corresponding to each of the 32 channels.

Self-check: The system automatically checks itself after resetting.

The VMIVME-4140-001-VMIVME4140 self-test register indicates success or failure and can indicate the channel where the failure occurred.

Front panel status LED: After a lights up, the system resets. The indicator light is off to complete self-check and automatic calibration. Leds can also be turned on and off under software control. VMEbus compatibility: The address modification bit is a jumper

Select and decode to support non-privileged, supervisory, non-privileged persons or Supervisory Board members.

Output data transfer: The output data is stored in 32-bit 16-bit registers. The board can be configured by software to accept two complementary or offset binary data. However, changes may be initiated by register access and output dual buffering allows all channels to be updated synchronously by software or external triggers.
