Build your own oscilloscope and learn how to visualize signals. See the signals you learn about in real life!

Despite the low cost, this oscilloscope has a lot of features found only on expensive units like signal markers,

frequency, dB, true RMS readouts,... A powerful auto-setup function will get you going in a snap!

Note: This scope cannot be used to perform measurements on voltages higher than 30Vpp.

Maximum input voltage: 30Vpeak

(AC + DC).

Maximum sample rate: 1MS/s for repetitive

signals. Measurements can be performed

up to 100kHz.

Timebase range: in 15 steps,

10µs/division to 500ms/division.

Dimensions:

80 x 115 x 40mm / 3.14 x 4.52 x 1.57”

Full auto set up for: Volt/div and time/div

(or manual).

Input sensitivity range: in 6 steps,

100mV/division to 5V/division.

Educational

Input coupling: DC and AC.

LED backlight LCD.

Time and voltage markers readout.

Readouts: DC, AC+DC, true RMS, dBm,

Vpp, min. & max. Battery operated: 4 x AAA batteries

(max. 100mA).

hints

1. Assembly (Skipping this can lead to troubles ! )

Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully.

1.1 Make sure you have the right tools:

• A good quality soldering iron (25-40W) with a small tip.

• Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’ and

will protect the tip, and enables you to make good connections. When solder rolls off the tip, it needs cleaning.

• Thinraisin-coresolder.Donotuseanyuxorgrease.

• Adiagonalcuttertotrimexcesswires.Toavoidinjurywhencuttingexcessleads,holdtheleadsotheycannot

ytowardstheeyes.

• Needle nose pliers, for bending leads, or to hold components in place.

• SmallbladeandPhillipsscrewdrivers.Abasicrangeisne.

)For some projects, a basic multi-meter is required, or might be handy.

1.2 Assembly Hints :

• Makesuretheskilllevelmatchesyourexperience,toavoiddisappointments.

• Follow the instructions carefully. Read and understand the entire step before you perform each operation.

• Perform the assembly in the correct order as stated in this manual.

• Position all parts on the PCB (Printed Circuit Board) as shown on the drawings.

• Values on the circuit diagram are subject to changes, the values in this assembly guide are correct*.

• Usethecheck-boxestomarkyourprogress.

• Please read the included information on safety and customer service.

*Typographicalinaccuraciesexcluded.Alwayslookforpossiblelastminutemanualupdates,indicatedas‘NOTE’onaseparateleaet.

1.3 Soldering Hints :

1. Mount the component against the PCB surface and carefully solder the leads.

2. Make sure the solder joints are cone-shaped and shiny.

3. Trimexcessleadsascloseaspossibletothesolderjoint.

Construction

* metallm resistor !

This educational LCD oscilloscope consists of three parts: the base PCB, the display PCB and the rear panel. First

we assemble the display pcb and then the base PCB. On the display module we mount components on both sides.

We start at the solderside and nish with the components on the component side.

STEP 2: Thin the wires.

Step 4: Solder the cables on the PCB.

STEP 1: Strip both cables and twist the wire

ends of each cable.

STEP 3: Mount both cables as shown in the

drawing.

17 Mounting the test leads

Tip: Start with one cable and then do

the other.

18 Mounting the battery holder

STEP 1: Stick one part of the included hook-and-loop strap (hooks)

on one of the long sides of the battery holder.

STEP 2: Connect the battery holder to the base

PCB using the included red and black mounting

wires. Mind the polarity!
