当使用可选输出隔离硬件时，模拟输出精度VMIVME-4100以多种选项配置提供给用户。其中一个是与前面第3.3.节中讨论的其他VMIVME板一起使用时，使用内置测试功能。内置测试硬件具有所有16个通道的模拟输出隔离开关，可通过软件命令关闭/关闭。这些开关与P3接头处的模拟输出和用户连接设备串联。这些开关的接通电阻约为100欧姆（值）。如果用户连接的负载没有高阻抗输入，则可能会引入电压分配错误。例如，如果R（LOAD）为10 kΩ, 然后引入1%的误差。R（LOAD）应为1兆欧或更大，误差为.01%或更小。技术手册的本节提供了与VMIC产品保养和维护相关的信息。如果产品出现故障，用户应验证以下内容：a.软件b.系统配置c.电气连接d.跳线或配置选项e.电路板完全插入其正确的连接器位置f.连接器插脚清洁且***g。从VME总线卡框架h中插入或卸下电路板时，不会干扰相邻电路板的组件。电缆和I/O连接的质量

ANALOG OUTPUT ACCURACY WHEN OPTIONAL OUTPUT ***LATION HARDWARE IS USED The VMIVME-4100 is offered in several option configurations to the user. One of which is the use of Built-in-Test functions when used with other VMIVME boards as discussed previously in Section 3.3.The Built-in-Test hardware features analog output ***lation switches for all 16 channels that can be turned OF/OFF by software commands. These switches are in series with the analog output and the user-connected device at the P3 connector. These switches have an ON resistance of approximately 100 ohms (max). If the user-connected load does not have a high impedance input, then a possible voltage division error is introduced. For example, if R(LOAD) is 10 kΩ, then a 1% error is introduced. R(LOAD) should be one megohm or greater for an error of .01% or less.This section of the technical manual provides information relative to the care and maintenance of VMIC’s products. Should the products malfunction, the user should verify the following: a. Software b. System configuration c. Electrical connections d. Jumper or configuration options e. Boards fully inserted into their proper connector location f. Connector pins are clean and free from contamination g. No components of adjacent boards are disturbed when inserting or removing the board from the VMEbus card cage h. Quality of cables and I/O connections
