  • Page 45: General Adjustment Procedure

    General Adjustment Procedure This chapter explains how to adjust the SDG5000 series generator for optimum operating performance.  Channel Adjustment which includes three steps: feedback channel adjustment, channel self adjustment and vertical accuracy calibration.  Feedback channel Adjustment which act as a standard calibration module, providing the accuracy assurance for Self Adjust.

  • Page 46: Scripts For Calibration

    Scripts for Calibration SIGLENT provides a free suite for calibrating SDG series products, in which all scripts are written in Python. Customers can download the package from the website and just run the scripts to complete the whole calibration process after some preparation works.

  • Page 47: Channel Adjustment

    Channel Adjustment The channel adjustment includes three parts: feedback channel adjustment, channel self adjustment and vertical accuracy calibration. 1. Turn on the generator. 2. Connect the DMM, PC and SDG5000 generator as shown below: 3. Double click and run the script ChannelAdjust.py prepared previously. Then change the channel connection according to the prompt message.
  • Page 48 Feedback Channel Adjustment The internal feedback channel receives the feedback signal from all the other channels that are performing self adjustment. This adjustment acts as a standard test module and must be performed prior to Self Adjust to make sure it is performed based on a best adjusting accuracy.
  • Page 49 Channel Self Adjustment 1. This adjustment is for internal control channel and signal channel. Through feedback circuits of the feedback channel and signal channel, this adjustment helps to obtain the actual working performance for components from signal channels. After the feedback channel adjustment completed, disconnect the two BNC cables on channel 1 and channel 2.
  • Page 50 Vertical Accuracy Calibration This adjustment aims to calibrate the amplitude at low frequency, using a DMM with high precision. The SDG5000 begins this portion of the calibration after the completion of the self adjustment process. It calibrates the Sine wave with a 10 kHz frequency and selects several amplitudes to calibrate.

  • Page 51: Frequency Response Adjustments

    Frequency Response Adjustments This adjustment aims to obtain the actual frequency response characteristics of the signal channel, thus to perform appropriate compensation. Since the waveform amplitude will decrease as the input frequency increases, it is essential to compensate for the amplitude to match it to the frequency. This adjustment should be performed after the channel adjustment.
