I have a number of oscilloscopes; the only one I didn’t build or rebuild is my DSO Nano oscilloscope. The vacuum tube oscilloscopes were weeklong projects unlike the DSO 062 oscilloscope that took only two hours to assemble. This is my second DSO 062 LCD Oscilloscope my other one managed to grow legs and go on a trip without me. I purchased the kit from Canada Kit http://www.canakit.com/ for $60.oo, however if you Google DSO 062 LCD Oscilloscope you can find them everywhere.
Since the Assembly Notes have step by step instructions on how to assemble the scope most of this Instructable will be on the things not in the Assembly Notes. And little tricks I learned through the years working in electronics.
Step 1: The Kit
When your DSO 062 Oscilloscope arrives in the mail open it, inside you will find several packages of parts and two pieces of paper marked, “General Assembly Guide and 062 Oscilloscope Quick Reference”. Put everything back in the box but the paper marked “062 Oscilloscope Quick Reference”.
Take the quick reference to your computer, on the bottom of the quick reference it says “For Complete and updated documents please visit: http://www.jyetech.com that is JYETECH.
On your computer go to:
Click on English
Under Quick Links Click on Documents
Down load all the files under models 06203P, 06203KP, and 06204KP for all three models it is the same files.

How to Program 062 Oscilloscopes
Step 2: Print Files
Print the pdf files:
The reason for printing the pdf files is so you can tick off the steppes as you follow the assembly notes.
Step 3: Check the Parts
From the printed pdf files check the parts make sure all the parts are in the kit and check them to be sure they fit the circuit board. Whether deliberately or by accident it is not uncommon for parts to be substituted in kits, so make sure they are the right parts and they fit before you start to assemble your oscilloscope.
Step 4: Tools
If all the parts are in the kit and they fit in place you will need these tools to assemble the oscilloscope.
Power supply 9 to 12 volts DC 300 ma
Needle nose pliers
Step 5: Assembling the Oscilloscope
Take your time and follow the step by step instructions of the assembly notes, the only thing I would add to them is use the long spacers to hold the circuit board up from your work table.
Cut off the excess leads off the through hole parts as you add them to the circuit board or it will be like trying to solder through a hair brush.
Your joint is good on the through hole parts if you can pluck the end of the excess wire lead and it rings like a guitar string.
Step 6: Testing
After assembling the circuit board completely you need to test the oscilloscope before putting the front and back plates on.
Connect the power to the oscilloscope.
The LCD should light up.
“Boot loader” then should come on the LCD.
The LCD should switch to WWW.JYETECH.COM.
Last F= and Hz
This indicates the oscilloscope is functioning normally, if it doesn’t display this on the LCD follow the Troubleshooting Guide.
Step 7: Assembling the Probe
Strangely the assembly notes don’t tell you how to put the probe together, so in this step I will.
After the oscilloscope is completely assembled gather the parts for the probe.
Strip ¼ inch of the insolation off both ends of the small red and black wires and solder one end onto the alligator clips.
Slip the rubber boots on to the alligator clips and slip the small shrink tube on to the wires.
Next strip ½ inch of the insolation off the outside layer of the coaxial cable.
Twist the outer braded wire.
Strip ¼ inch of the insolation off the inner wire.
Solder the red wire to the inner wire and the black wire to the outer braded wire.
Slip the shrink tube over the joints and heat to shrink then slip the larger shrink tube over the two joints and heat to shrink.
Step 8: The BNC Connector
Slip the BNC connectors collar over the coaxial cable and strip the end as before.
Solder the center wire to the center tab of the BNC connector and the outer braded to the outer tab of the BNC connector.
Then screw the collar back on the connector.
Step 9: Testing the Probe and Oscilloscope
To test the probe and oscilloscope I connected the probe to the built in signal generator of my DSO Nano oscilloscope.
Now when I power up the oscilloscope it said F= 1000Hz after booting up.
Then I checked the other functions of the oscilloscope.
Step 10: Making a Portable Power Supply
All the parts for this I got at my local Radio Shack the Source here in Canada.
8 AA batteries
1 9 volt battery terminal
1 coaxial power plug
1 12 volt AA battery holder
Slip the shrink tube over the wires of the 9 volt battery terminal and heat to shrink.
Unscrew the collar of the coaxial power plug and slip it over the wire of the 9 volt battery terminal.
Then solder the red wire to the center tab of the coaxial cable connector and the black wire to the outer tab and screw the collar back in place.
Place the 8 AA batteries in the battery holder, clip the 9 volt battery terminal to the holder, and plug it into the oscilloscope and watch it boot up.
Step 11: And We Are Done
I like to keep the box the kit came in, when I am finished assembling everything it all fits in the box nicely so things don’t get lost. If everything goes right from kit in box to working oscilloscope 2 ½ hours and about $70.oo.
