Programming Example: Create a stair-step waveform using Python and PyVISA using LAN (SDG1000X, SDG2000X, SDG6000X)

Programming Example: Create a stair-step waveform using Python and PyVISA using LAN (SDG1000X, SDG2000X, SDG6000X)

The SIGLENT SDG series of arbitrary waveform generators can use waveforms created programmatically. The waveform data can be sent as individual samples formatted as binary little-endian, 2s complement values. In this programming example, we create a 10 point arbitrary waveform that starts at the least-significant bit and steps up to the most-significant bit to help with understanding the req...

Inter Modulation Distortion (IMD) testing

Two SIGLENT SDG owners and Amateur Radio operators and frequent experimenters, Steve Ratzlaff AA7U and Everett Sharp N4CY, got together and built a very thorough test procedure for testing Intermodulation Distortion (IMD) on a Loop Amplifier using a SIGLENT SDG2042X generator and SSA3021X spectrum analyser. IMD is an important test for verification of audio amplifiers and radio receivers as hig...

Multi Channel function generator synchronisation

1. Introduction Multi-channel function generators are useful in many situations. For example, in Radar testing the generator needs to output several phase coherent signals and for the phase to be independently adjustable for each signal. In 3-phase power line harmonic distortion testing, a 4 channel generator is required to simulate the multiple voltages and currents. ...

Secure products without K-lock slots

Many products have Kensington, or K-lock slots to help provide a location to secure a cable lock or other device to help prevent theft. Some products do not have locations for cable lock connections. In this case, we recommend using a special glue or physical attachment system to secure the cable to the case of the instrument. Here is an example: https://www.kensington.com/p/products/s...

AWG Basics

Many electronic designs feature the ability to monitor or measure input signals and then perform another task or function based on that input signal. A simple example could be a circuit that looks for an input voltage to exceed a specific amount and triggers another action after it occurs. In such cases, having the ability to configure and deliver a known or simulated signal can be a critical addi...

The basic output waveform and related parameters of the arbitrary waveform generator

Traditional function generators can output standard waveforms such as sine waves, square waves, and triangle waves. However, in actual test scenarios, in order to simulate the complex conditions of the product in actual use, it is often necessary to artificially create some “irregular” waveforms or add some specific distortion to a waveform. Traditional function generators can no longer meet t...

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 distribut...

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 g...

Analysing GSM Radio Protocol with a Siglent SDS2000X Plus Oscilloscope

We took a retired Siemens A36 cellphone to learn the capabilities of this new Siglent scope. Available documentation and medium-density PCB of the selected A36 made the signal probing easy to implement. We used TEK P6243 active probes initially for their low capacity loading but changed to passive probes later as monitored signals proved to be quite robust. ...

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 ...

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

The short list of differences between the X and the 2 channel XE (SDSs1202XE) is as follows:– X has 50 ohm/ 1 MOhm selectable input impedance. XE only has 1 MOhm fixed. You will need a 50 ohm matching through adapter if you wish to connect to 50 Ohm circuits/minimize ref...

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...
