Instrument communication using instrument drivers

您需要创建一个接口对象，例如GPIB或者i2c, to communicate with instruments, as described in many of the sections of the documentation. You can also create a device object that allows you to configure and query an instrument without knowledge of its command set. See创建和连接设备对象for more information about using device objects.

Using a NI Switch Module and a NI DMM to Perform Resistance Measurements

A switch module consists of an array of controllable relays/switches that can be arranged and addressed to provide various connection configurations. When used with an appropriate terminal block, an NI switch module can be configured to use a certain switch topology, such as multiplexer or matrix topology with one- or multi-wire switching modes. One common application is to combine one or more measuring instruments with a switch module to perform automated measurements on a number of devices or circuit test-points. This example uses an NI switch module together with an NI digital multimeter (DMM) to measure the resistance of 5 resistive devices in two-wire resistance measurement mode.
