RIGOL DS1054Z - FEELTECH FY32xx AUTOMATED FREQUENCY RESPONSE ANALYSIS

TESTED ON WINDOWS ONLY

Features

Amplitude and phase semilogarithmic plots
Average acquisition mode, with 4 waves average (for f>2Hz) or high resolution mode (for f<2Hz)
Logaritmic or linear frequencies span
Automated setup
Automated restore of the previous scope's settings
Automated fine adjustment of the vertical scale for maximized voltage sensitivity, with clipping detection
Sense triggering errors and try to correct them. If it's not possible to trigger the signal, a red octagon is plotted in amplitude and phase plots for that frequency
For very low amplitude values (vpeak<5mV) phases measurements are considered not accurate and are marked with yellow dot in the phase plot

GPIB drivers are needed.
Connect both scope and signal generator to PC with usb cables.
Connect signal generator CH1 output and scope CH1 to the Device Under Test input;
Connect DUT's output to scope CH2.
SET SCOPE ADDRESS AND SIGNAL GENERATOR SERIAL PORT into BodePlot.py script before starting it.
On windows, Feeltech Signal generator COM port can be founded under 'Device Manager->COM Ports'
Be sure to have all the needed python packages (if not, install them with pip)

While scope is connected with usb cable to the PC, run this script:

import pyvisa
rm = pyvisa.ResourceManager()
rm.list_resources()

You have to find something like this: USB0::0x1AB1::0x04CE::DS1ZA223107793::INSTR this is the scope address to copy into the main script.

This is the output for an R-C low pass filter with R=1k, C=10n
