How to install the USB driver for PCSU200?

Connect the device to a free USB port. When Windows asks for the driver, select 'Install from a specific location' and browse to the PCSU200Driver folder.

What to do if the device is not detected by the software?

Disconnect and reconnect the USB cable. If the problem persists, go to Options > Hardware Setup and enable demo mode to use the software without a device.

How to use the oscilloscope?

Connect the test signal to CH1 or CH2 input. Click Run, then adjust Volts/div and Time/div. You can also click Autoset for automatic configuration.

How to generate a signal with the function generator?

In the Function Generator tab, click on the desired waveform (sine, square, triangle). Set the frequency using the slider or by entering a value, then adjust the amplitude.

How to analyze the spectrum of a signal?

First observe the signal on the oscilloscope. Switch to the Spectrum Analyzer tab, click Run, and select the appropriate frequency range.

How to record transient signals over a long period?

In the Transient Recorder tab, set the channel, volts/div and time/div. Click Run. For continuous recording, enable AutoSave Data in the File menu.

How to plot a Bode diagram?

Open Circuit Analyser. Connect the generator output to the circuit input and oscilloscope channel CH1 to the output. Set the parameters (V Range, Frequency Range) and click Start.

What safety precautions should I take?

Never exceed 30 V (AC+DC) between the probe and ground. Ensure the tested circuit is galvanically isolated from the mains. Use an isolation transformer if necessary. Avoid USB hubs.

How to calibrate the oscilloscope probe?

Use the Probe Test button of the function generator to produce a calibration signal. Connect the probe to the generator output and adjust compensation if necessary.

During recording the screen can differ from the actual measurement.

Events happening between two sample acquisitions will be missed if a too slow time/div is set.

THE BODE PLOTTER MODULE :

What ? : Due to the unique scope and generator combination, an automated Bode plot function is possible. This results in a powerful tool for amplifier or filter measurements.
