Programming Preparations
Before programming, you need to make the following preparations:
1 Make sure that your PC has installed the NI-VISA library (can be downloaded from NI website:
http://www.ni.com/visa/). Here, the default installation path is C:\Program Files\IVI Foundation\VISA.
2 Here, the USB interface of the M300 series Data Acquisition/Switch System is used to communicate
with the PC and please use a USB cable to connect the USB DEVICE interface at the rear panel of the
M300 to the PC. You can also use the LAN, RS232 or GPIB interface to communicate with the PC. Note
that the end mark of the command sent through the RS232 interface is "\r\n".
3 Turn on the instrument after connecting the instrument and PC.
4 At this point, the "Found New Hardware Wizard" dialog box appears on the PC. Please follow the
instructions to install the "USB Test and Measurement Device".
5 Acquire the USB VISA descriptor of the M300 series Data Acquisition/Switch System: press Utility 
I/O  USB  Device and the VISA descriptor is displayed at the interface, as shown in the figure
below. Here, the VISA descriptor of the M300 series Data Acquisition/Switch System is
usb0::6833::3200::M300123123123::0::INSTR.
By now, the programming preparations are finished.
