SAFETY & WARNINGS Instruments grounds are interconnected and connected to PC ground. Max. voltage between probe tip and ground: 30V AC+DC at all times! Before performing any measurement, make sure that the circuit is galvanically seperated from the AC power (mains)! If necessary, use a safety isolation transformer. HOW TO INSTALL PC-LAB200 SOFTWARE?

HARDWARE SET-UP (CLOSE ALL PROGRAMS BEFORE CONTINUING) USB driver install: Connect your PCSU200 unit to a free USB port• Follow the on screen driver installation procedure.• If Windows asks for Windows Update, select “not at this time”• Install the driver from a specifi c location, then browse your drive and select the folder “PCSU200Driver”. • (press “next”) If Windows indicate “has not passed Windows logo testing…” select “Continue Anyway”.• After fi nishing, you can check the driver installation in the Device Manager list. • It is possible that the PC asks to “restart” for proper installation• Starting the software : Locate the Pc-Lab200 software shortcuts (programs.. Pc-Lab200 …) Click the icon to start the main program. “loading, please wait” should appear. Then the channel indicator LEDs must go ON. (*) The main program automatically launches the Oscilloscope and generator screen, which is shown on the next pages. Should you receive an error (ex. If no unit is detected), disconnect and reconnect the USB cable and try again or, if you want to access the demo mode (no unit is needed) : - Click the Options menu, and select ‘Hardware Setup’ > demo mode Note: At fi rst time power-up, the oscilloscope will calibrate itself automatically.• The actual screens can differ from the one shown in this manual. •7 THE FUNCTION GENERATOR MODULE : What ? : Most common wave-forms are accessible at the touch of a button. A library with special functions is provided, as well as a Wave Editor, to create virtually any kind of waveform. How ? : Click on the desired waveform (• 1). Select the desired frequency range (• 2). Set the exact frequency by sliding (• 3) or click the frequency readout (4) and enter a value. Adjust the amplitude (• 5) (• 6) shows a simulated preview of the output waveform The ‘More Functions’- button : The ‘More Functions’-button gives access to special purpose waveforms such as arbitrary waveforms, and frequency sweeps. It also gives access to the waveform library. Note: The Probe test button (7) makes the generator output a signal, suitable for your scope probe calibration at X10 setting.

THE OSCILLOSCOPE MODULE : What ? : The Oscilloscope module offers a feature-packed, easy to use digital storage oscilloscope. How ? : Connect the circuit under test to the scope input (observe the max. input rating of the scope!) or connect to • the generator output. Start measuring with “trigger off” (• 6) Press ‘RUN’ (• 7) Choose the desired channel and volts/div setting or press “Auto-set” (• 2) Choose the appropriate time/div setting (• 8) To enable triggering : Select trigger channel (• 5) Select trigger edge (• 4) Set trigger to ‘ON’ (• 6) Set trigger level by sliding (• 3). The trigger mark is displayed on the left hand side of the signal display (1)

Channel On / Off and generator output are indicated by a LED on the unit.

THE SPECTRUM ANALYSER MODULE : What ? : Powerful feature which allows visualization of the frequency spectrum of a signal, using FFT (Fast Fourier Transform) analysis. How ? : Connect the scope input to the circuit under test. (observe the max. input rating of the scope!) Or use the • internal generator output. First observe the signal on the scope screen (see previous page).• Check that the signal is not over the maximum of the screen.• Start the spectrum analyzer.• Press ‘RUN’ (• 1) Select the appropriate frequency range. Make sure your setting will capture any signal change of interest (• 3). If wanted set the appropriate channel and volts/div setting (• 2)

THE TRANSIENT RECORDER MODULE : What ? : Record occasional events and log slow changing processes automatically, e.g. battery charge cycles, temperature changes,... or track intermittent faults in electronic circuits. Automatic data storage allows over one year of continuous recording ! How ? : Connect the scope input to the circuit under test. (or the internal generator at a low frequency)• Select the appropriate channel and volts/div (or volt range) setting (• 1). Select the appropriate time/division setting (• 3). Press RUN (• 2) to start recording. Press RUN again, to stop the measurement, or use the “Single” button to make a single screen measurement. For continuous recording with auto-save to your HD, select ‘AutoSave Data’ from the ‘File’-menu.

Notes: 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•11 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 amplifi er or fi lter measurements. How ? : Enable the Circuit Analyser window (• 1) Connect the scope CH1 input to the output of the circuit or unit under test.• Connect the generator output to the input of the circuit or unit.• Adjust the generator output (• 2) to a suitable level. Adjust the setting of the Bode plot module like Volt range (• 3) Volt scale, frequency start and stop range (4)... Press ‘Start’ (• 5) and observe the screen and measurement window (6) If the signal is out of the screen range, adjust the Voltage range or generator output level.•
