Power Supply Design: Load Step Response with a SIGLENT DC Electronic Load
April 3, 2020
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. … Continued
Analyzing GSM Radio Protocol with a Siglent SDS2000X Plus Oscilloscope
March 10, 2020
Two SIGLENT users, Karel and Simon Sotek, email2@avanaconsulting.de recently took a SIGLENT SDS2354X Plus oscilloscope and investigated a GSM cell phone signal. Here is their report: 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 … Continued
Programming Example: SDS Oscilloscope save a copy of a screen image via Python/PyVISA
February 26, 2020
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 … Continued

Programming Example: SDS Oscilloscope screen image capture using Python over LAN
March 8, 2019
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 … 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) *** #Example that scans a … Continued
