Bode Plot of a filter using an oscilloscope and function generator

September 12, 2018

A Bode plot is a method of graphically displaying the frequency response of a system or device-under-test (DUT). Commonly, the magnitude and phase response of the device are plotted with respect to frequency using a shared horizontal frequency axis as shown in the example below:   By showing both the magnitude and phase information on … Continued

Programming Example: List connected VISA compatible resources using PyVISA

August 30, 2018

PyVISA is a software library that enables Python applications to communicate with resources (typically instruments) connected to a controlling computer using different buses, including: GPIB, RS-232, LAN, and USB. This example scans and lists the available resources. It requires PyVISA to be installed (see the PyVISA documentation for more information) *** ***** Here is the … Continued

SDS FFT performance on low frequency signals

May 23, 2018

Like many modern oscilloscopes, the SIGLENT SDS series feature FFT math functions that calculate frequency information from the acquired voltage vs. time data. FFT stands for Fast Fourier Transform, and is a common method for determining the frequency content of a time-varying signal. Converting time domain data to the frequency domain makes measuring characteristics like … Continued

Programming Example: Retrieve data from an XE series Oscilloscope using Kotlin

May 9, 2018

The SDS series of oscilloscopes all feature remote programming and data collection capabilities. They can be integrated easily into many automated test environments to ease the setup and data acquisition during testing. One of our helpful customers developed a nice programming example designed to set up and retrieve data from a SIGLENT SDS1202X-E Oscilloscope using Kotlin, … Continued

Quick remote computer control using LXI Tools

March 13, 2018

Introduction: There are many options for people considering remote communication and control of test and measurement instrumentation. In most cases, a computer is used to communicate to test instrumentation using USB or LAN connections. The computer can configure the instruments, collect and organize data, and present it in a useful and flexible way. Remote control … Continued

Generating an Activation Code (Option Code)

January 18, 2018

Introduction Many SIGLENT products have options that can be activated by entering a special activation code into the front panel. This note covers how to generate the activation code.   Setup Contact your Authorized SIGLENT sales office or distributor to obtain an Option Card. This is typically a document that is emailed as a PDF. … Continued

Using EasyScopeX Software to retrieve Average Waveform Data

October 24, 2017

Waveform averaging can be a useful method to decrease noise in a particular signal. The SIGLENT SDS series of oscilloscopes can easily collect average waveform data using EasyScopeX Software. NOTE: At this time, average waveform data is not able to be saved in CSV format via the front panel USB connection to a USB memory … Continued

Programming Example: Open Socket LAN connection using Python

October 20, 2017

Automating a test can dramatically increase the productivity, throughput, and accuracy of a process. Automating a setup involves connecting a computer to the test instrumentation using a standard communications bus like USB or LAN and then utilizing code entered via a software layer (like LabVIEW, .NET, Python, etc..) to sequence the specific instrument commands and … Continued

Verification of a LAN connection using Telnet

October 20, 2017

Automating a test can dramatically increase the productivity, throughput, and accuracy of a process. Automating a setup involves connecting a computer to the test instrumentation using a standard communications bus like USB or LAN and then utilizing code entered via a software layer (like LabVIEW, .NET, Python, etc..) to sequence the specific instrument commands and … Continued

Testing Open Socket Communications Using PuTTY

October 19, 2017

Many instruments include the ability to be controlled via a remote connection to a computer using an Ethernet connection. In many cases, these instruments require a special software library that can help establish and maintain the communications link between the instrument and controlling computer. This can be annoying for a few reasons… the software library … Continued
