Build Remote Communication 
RSA3000E supports communication with PC via USB and LAN interface for remote control. This chapter 
introduces in details how to use Ultra Sigma to send commands through the USB interface to control the 
analyzer. 
Operation Procedures: 
1.  Install Ultra Sigma (PC) software. 
You can download Ultra Sigma from the official website of RIGOL (www.rigol.com) and install the 
software according to the installation wizard. 
2.  Connect the analyzer to the PC and configure the interface parameters for the instrument 
RSA3000E supports three communication interfaces: USB and LAN. 
Figure 1-1 RSA3000E Communication Interface 
(1)  Remote communication via USB: 
Use the USB cable to connect the USB DEVICE interface on the rear panel of RSA3000E to the USB 
HOST interface of the PC. 
(2)  Remote communication via LAN: 
  Make sure that your PC has been accessed to the local area network. 
  Check whether the local area network where your PC resides supports DHCP or auto IP mode. 
If not, you need to obtain the available network interface parameters, including the IP 
address, subnet mask, default gateway, and DNS. 
  Connect RSA3000E to the local area network by using a network cable. 
  Press System  Interface  LAN to configure the IP address, subnet mask, default 
gateway, and DNS for the instrument. 
3.  Check whether the connection is successful. 
Run Ultra Sigma, and then search for the resources and right-click the resource name. Select "SCPI 
Panel Control" to open the SCPI command control panel. In the SCPI command control panel, input a 
correct command. After that, click Send Command first and then click Read Response. Or you can 
also directly click Send & Read to verify whether the connection works properly. The following figure 
takes USB interface as an example to illustrate it.
