Generating an Activation Code (Option Code)

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 Authorised SIGLENT sales office or distributor to obtain an Option Card. This is typically a document that is emailed as a PDF. A typical Option Card will contain the followi...

EasyPulse Technology and Its Benefits

INTRODUCTION: The majority of modern arbitrary/function waveform generators utilise DDS technology (Direct Digital Synthesis), but there are a few obvious defects using this technology directly. To solve these disadvantages, SIGLENT invented a pulse generating algorithm called EasyPulse technology. In this note, we will describe the basics of DDS and how EasyPulse can help get the best performa...

Analysing GSM Radio Protocol with a Siglent Oscilloscope

This updated case study uses a legacy GSM handset to demonstrate a still-relevant measurement method: correlate analogue baseband activity, radio state changes and supply current on one timebase. The cellular technology is historical, but the workflow applies to modern radios, wireless sensors and battery-powered embedded products. Treat the handset and its measured values as the worked examp...

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

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, a free open source c...

Comparison / Differences between the SDS1000X and SDS1000X-E oscilloscope families

The original SDS1000X versus SDS1000X-E comparison has reached the end of its useful life as a buying guide. A current entry-level decision is better framed around measurement quality, channel count, memory, protocol tools and workflow rather than two superseded families. Start with the measurement, not the badge 12-bit captureMore vertical codes can reveal small changes on larger signals,...

Programming Example: List connected VISA compatible resources using PyVISA

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) *** #Example that scans a compute...

SDS FFT performance on low frequency signals

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 phase noise and harmonics...

Programming Example: SDS Oscilloscope screen image capture using Python over LAN

Here is a brief code example written in Python 3.4 that uses a socket to pull a display image (screenshot) from a SIGLENT SDS1000X-E scope via LAN and save it to the local drive of the controlling computer. NOTE: This program saves the picture/display image file in the same directory that the .py file is being run from. It will overwrite any existing file that has the same name. Download P...

Measuring Power Supply Control Loop Response with Bode Plot II

Introduction Stability is one of the most important characteristics in power supply design. Traditionally, stability measurements require expensive frequency response analysers (FRA) which are not always available in a laboratory. SIGLENT has released Bode Plot Ⅱ features to the SIGLENT SDS1104X-E, SDS1204X-E, SDS2000X-E, SDS2000X Plus, and SDS5000X series of oscilloscopes. When combined with...

Measuring the Modulation Index of an AM Signal using an FFT

Introduction In AM schemes, the modulation index refers to the amplitude ratio of the modulating signal to the carrier signal. With the help of Fast-Fourier-Transforms (FFT), the modulation index can be obtained by measuring the sideband amplitude and the carrier amplitude. In this application note, we are going to show a convenient method of using the new Peaks/Markers function (Available on the...

Programming Example: SDS Oscilloscope save a copy of a screen image via Python/PyVISA

Here is a brief code example written in Python 3.4 that uses PyVISA to pull a display image (screenshot) from a SIGLENT SDS oscilloscope via USB and save it to a drive on the controlling computer. NOTE: This program saves the picture/display image file to the E: drive, which may or may not exist on the specific computer being used to run the application. Download Python 3.4, connect a SIGLE...

Power Supply Design: Load Step Response with a SIGLENT DC Electronic Load

Building a power supply that can handle various loads without oscillating can be a challenge. Computational models and computer simulations can help get your design headed in the right direction, but physical testing is essential to proving the performance of your design. One method of quickly determining stability is to use a load step response. In this test, a DC electronic load is used to...
