Siglent_SDS1202X-E_VISA_Scilab

Scilab 6.0.2 functions for easy, data acquisition from the Siglent SDS1202X-E oscilloscope via USB or Ethernet. The input-buffer size automatically scales depending on the oscilloscope's sampling settings!

Supported models

• SDS1xxxCFL - series
• SDS1xxxA - series
• SDS1xxxCML+/CNL+/DL+/E+/F+ - series
• SDS2xxx/2xxxX - series
• SDS1xxxX/1xxxX+ - series
• SDS1xxxX-E/X-C - series

Known issues

• Since Scilab 6.0.2 and Visa Toolbox 0.9.1 don't support a single stream of binary data, a temporary workaround has to be used. This workaround somehow limits the sample count to:
  • USB connection: 7Mpts
  • Ethernet connection: 28kpts

Installation

There is no installation required. Just download the Scilab files (*.sci-files from Releases) and move them into your work folder.

Requirements

• NI-VISA 19.5
• Scilab 6.0.2
• VISA Toolbox 0.9.1

How to use

Following functions can be called:

• [vDiv, tDiv, offs, sCount, sRate] = determineAcquisitionSettings(connStr, channel)
  • vDiv - Volts/Devition
  • tDiv - Time/Devition
  • offs - Vertical offset
  • sCount - Number of samples
  • sRate - Sampling rate
  • connStr - Enter VISA USB resourcename (e.g. 'USB0::0xF4EC::0xEE38::0123456789::INSTR') or enter the IP address (e.g. '10.0.0.12'). If you don't enter anything or just '' the IP address stored in the DEFAULT_IP-variable will be used.
  • channel - Enter the oscilloscope channel (e.g. 1). If you don't enter anything or just '' the channel stored in the DEFAULT_CHANNEL-variable will be used.
• [timeOut, dataOut, sRate] = acquireOscilloscopeData(connStr, channel) (uses determineAcquisitionSettings)
  • timeOut - Array containing the time axis
  • dataOut - Array containing the meassured data
  • sRate - Sampling rate
  • connStr - Same as in the functions above.
  • channel - Same as in the functions above.
• acquireAndDisplay(connStr, channel) (uses acquireOscilloscopeData)
  • Plots the acquired data into a new figure. Besides that, it returns the most important signal properties to the command window (see example below).
  • connStr - Same as in the functions above.
  • channel - Same as in the functions above.
