Setting up a test signal

The PicoScope 2205A has a built-in signal generator and arbitrary

waveform generator. You can use this to test your scope and to

familiarize yourself with the software. If your scope doesn’t have a

signal generator, any signal source will do: an audio output from your

MP3 player, phone or PC is suitable.

•Attach one of the oscilloscope probes, supplied with your scope, to

the connector marked A on the front of the scope. This connector

is the channel A input.

•Remove the probe hook, if one is fitted, by pulling it away from the

probe.

•Insert the probe tip into the centre

of the connector marked AWG on

the oscilloscope. This connector is

the signal generator and arbitrary

waveform generator output.

Support the probe so that there is

no bending force on the probe tip.

Alternatively, you can use a BNC-to-

BNC cable - this will give you better

signal quality than a scope probe.

•Click the signal generator button in PicoScope:

•In the dialog (control box) that opens, click

Signal On:

You should now see a waveform on the PicoScope display:

At this stage the position of the waveform is unstable because there is

no trigger. We shall correct this later.

Introduction

PicoScope 6 is the oscilloscope software supplied with all PicoScope®

oscilloscopes. All the advertised features are included in the purchase

price of your oscilloscope, so there are no expensive add-on software

modules to buy later.

What devices can I use?

You can use PicoScope 6 with the following devices:

•PicoScope 2000 Series oscilloscopes

•PicoScope 3000 Series oscilloscopes

•PicoScope 4000 Series oscilloscopes

•PicoScope 5000 Series oscilloscopes

•PicoScope 6000 Series oscilloscopes

•PicoLog 1000 Series data loggers

•DrDAQ educational data logger

For the PicoScope 9000 Series, separate documentation is available

on our website.

For data loggers not mentioned above, see the documentation for the

PicoLog®software.

Getting started

Your PicoScope or PicoLog device is supplied with

all the accessories you need to get started: software

CD, USB cable and, if required, AC adaptor.

•Load the CD into your computer and allow the

installation program to start. If you don’t have a CD or a CD drive,

download the software (it’s free) from our website.

•Choose ‘Install’ and install the PicoScope software. (You can use

PicoScope with the above-mentioned data loggers as well as with

our PicoScope oscilloscopes.) A PicoScope icon will appear on your

Windows desktop.

•If your device requires a separate power supply, plug it in now.

•When the installation is finished, plug your device into the

computer using the USB cable supplied. Windows will indicate that

the device is being installed, and then tell you when it is ready.

•Start the PicoScope software by clicking

the icon on your Windows desktop:

Using PicoScope for the first time

You are now ready to begin using PicoScope. This guide will use the

PicoScope 2205A ultra-compact oscilloscope as an example, but

all the procedures described here are equally applicable to other

PicoScope devices.

Your first view of PicoScope will look like this:

Beginner’s Guide to PicoScope 6

Timebase

The timebase controls how much time is represented across the width

of the display. The higher the signal frequency, the shorter the timebase

you need.

Before experimenting with the timebase, switch the trigger type back

to Auto.

•Auto Setup chose a timebase of 500 µs/div (500 microseconds per

division) in order to show about five cycles of the input waveform.

There are 10 divisions, so this represents 10 x 500 µs = 5 ms in total

across the display.

•Change the Collection Time setting on the top toolbar to 1 ms/div:

The time across the width of the display is now 10 x 1 ms = 10 ms,

allowing 10 cycles to fit on the screen:

Starting and stopping

The Start/Stop button tells the scope when to capture data. If the

waveform doesn’t update when you expect it to, check that the button

is in the Running state as shown here:

•Click the button to switch between Running and Stopped modes.

•Pressing the space bar on the keyboard has the same effect.

Running Stopped

Auto setup

Before introducing some of the detailed adjustments that are possible,

we will try out the Auto Setup feature. In most cases this displays a

waveform on the screen that can be improved with further adjustments.

•Click the Auto Setup button:

PicoScope tries a number of possible settings until a waveform is

displayed:

Input range

Auto Setup sets the Input Range control for channel A to Auto. This

continually monitors the input signal and adjusts itself to use as much

of the input range as possible. If you prefer a fixed input range, you can

select one using the Input Range control.

•Try setting the range to ±2 V:

Triggering

By default, the trigger mode is None. This guarantees that the scope

will display the input signal but does not define the horizontal position

of the waveform. Triggering can be used to fix the waveform in position

on the screen.

•Click the Trigger control in the toolbar at the bottom of the PicoScope

window. This reveals a drop-down list of trigger modes.

•Choose Auto:

With the Auto trigger mode, PicoScope updates the display only when

it detects a stable waveform. The display should now look like this:

•Experiment with the other trigger modes.

Input range

Experiment with the other trigger modes.

the region of interest:

the selected region

to fill the display:

magnified:

Waveform buffer

When capturing waveforms continually in trigger modes other than

Single, PicoScope stores the 32 most recent waveforms in a buffer. (This

number can be changed in the Preferences menu.)

•To recall these waveforms, use the Previous and Next buttons on the

top toolbar:

Next to these buttons is the Buffer Overview button:

Click this button to open the Buffer Overview, which allows you to scan

through the stored waveforms:

•Click one of the waveforms in the overview, and PicoScope will

display it in the main view:

Zooming

You can magnify (or zoom) any part of the displayed waveform without

changing the oscilloscope settings. This is controlled by a zooming

toolbar that looks like this:

To zoom in on an arbitrary region of the waveform, click the Windowed

Zoom button:

To zoom in on an arbitrary region of the waveform, click the
