Programming the DSA815 allows you to automate measurements, streamline testing procedures, and perform complex analysis tasks. Before you start, make sure you have the necessary drivers installed on your computer. Also, establish a connection between your computer and the DSA815 using either a USB, LAN, or GPIB cable. You can find detailed instructions on how to set up the connection in the manual. This setup step is really important, you need a stable connection to your device to make the programming work. Once you're connected, you'll be using a command language called SCPI (Standard Commands for Programmable Instruments). SCPI is the standard language for controlling test and measurement instruments. It allows you to send commands to the DSA815 and receive data from it. The IRIGOL DSA815 programming manual provides a comprehensive list of SCPI commands. A basic command in SCPI usually consists of a mnemonic followed by a parameter. For example, to set the center frequency, you might use the command :FREQ:CENT 100MHz. In this command, :FREQ:CENT is the mnemonic and 100MHz is the parameter. The commands can also have sub-commands. For example, to set the start frequency, you can use the command :FREQ:STAR 10MHz, where :FREQ:STAR is the mnemonic and 10MHz is the parameter. Common commands include frequency settings, amplitude adjustments, and marker controls. Let's delve into some common commands, that are explained in detail in the IRIGOL DSA815 programming manual. The first one is setting the center frequency, this is crucial for selecting the part of the spectrum you want to analyze. The command typically looks like :FREQ:CENT <frequency>. For example, setting the center frequency to 1 GHz would be :FREQ:CENT 1GHz. Next up, adjusting the span, this determines the width of the frequency range displayed on the screen. The command is usually :FREQ:SPAN <frequency>. For instance, to set the span to 100 MHz, you would use :FREQ:SPAN 100MHz. The second most important command is to set the start and stop frequency, for that you will use commands like :FREQ:STAR <frequency> and :FREQ:STOP <frequency>. These commands define the lower and upper bounds of your displayed frequency range. The next command is related to amplitude control. This command sets the reference level, which is the top of your display screen. The reference level is essential for ensuring your signal amplitudes are properly scaled on the display. This command typically uses :DISP:REF <amplitude>. Setting the resolution bandwidth (RBW) is another key setting. The RBW affects the selectivity of your measurements. To set the RBW, you will use the command :BAND:RES <bandwidth>. Another important command is the sweep time, this command controls how long the analyzer takes to sweep across the frequency range. For that you can use the command :SWE:TIME <time>. Markers are also important tools. You can use commands to control markers to pinpoint specific frequencies and their corresponding amplitude. Using these commands, you can make the DSA815 analyzer perform various tests, as explained in the IRIGOL DSA815 programming manual.

Basic SCPI Commands

To help you get up to speed fast, here's a quick rundown of some basic SCPI commands you'll be using, as documented in the IRIGOL DSA815 programming manual.

If you send this command, the DSA815 will return its identification string (e.g., model number, manufacturer, and firmware version). Sending the command is usually as easy as it sounds. Then you must check the frequency commands. As we know, setting the center frequency is crucial. Use :FREQ:CENT <frequency> to set the center frequency. For example, to set it to 500 MHz, you'd send :FREQ:CENT 500MHz. Next, setting the span, this is important as it determines the width of the frequency range. Use :FREQ:SPAN <frequency> to adjust the span. If you want to see a 10 MHz span, send :FREQ:SPAN 10MHz. Then you have the commands to set the start and stop frequencies, you can also use this for frequency settings. :FREQ:STAR <frequency> and :FREQ:STOP <frequency> will help you define the start and end of your display range. For instance, to set the start to 100 MHz, use :FREQ:STAR 100MHz, and to set the stop to 200 MHz, use :FREQ:STOP 200MHz. When it comes to amplitude, you'll want to set the reference level. The command is :DISP:REF <amplitude>. For example, setting the reference level to 0 dBm, use :DISP:REF 0dBm. Another common command will be for the resolution bandwidth. The command is :BAND:RES <bandwidth>. If you need to set it to 100 kHz, send :BAND:RES 100kHz. The sweep time is also important, it defines the amount of time the analyzer spends sweeping the frequency range. The command is :SWE:TIME <time>. To set a sweep time of 1 second, you’d use :SWE:TIME 1s. Finally, you also have commands for markers. With markers, you can pinpoint specific frequencies and their amplitudes. These are only a few basic commands, for more commands and settings, always refer to the IRIGOL DSA815 programming manual.
