That is awful to see that it is almost double the price of the student version here in the US.  It is also interesting to note that there are three price levels.  There is the student, then academic, and then full price.  I am guessing that the academic would be for teachers.

 

I am glad, though, that you were able to get the information you needed to be able to purchase one.

@Elizabeth - I just checked out that link - they have the AD unit for A$199 Academic price (which I should be able to get as I'm on a course).    Have to do some overtime to pay for it.....  Thanks very much again.

@Elizabeth thanks for that, I'll check it out later (jsut about to go to work).   I dealt with a different company some time ago who said they'd come back to me with a price but never did...my NI Mydaq is OK for very basic stuff but really no good for anything more than basic AF stuff.  Thanks again.

Sixscrews, thanks for contributing your thoughts.  I think that your advice is a really good recommendation for those that are looking to step up into the next level of devices.  I admit that the current recommendation on the oscilloscope is geared towards an entry/mid level person that is trying to be able to do a wide range of designs. 

 

As you indicated, I too am looking to upgrade my scope.  I am looking at the $800-$1500 range devices.  I think that it may yet be a few years before I make that jump.

All the pieces are good here but I would suggest investing in a top-notch oscilloscope.  I have a four channel Tek 2014 ca 2003 that always works and doesn't mind getting exposed to line voltage (120/240VAC) when I'm not being as careful as I should be (no discussion about exposing my personal wetware to same).  Similar scopes (non-Tek) go for under $1k these days and good 'scope skills will carry you far in tracking down things that go bang in the night....

The OV tolerance is one of the big difference between USB based devices and commercial 'scopes - commercial units are rated for CAT II (or CAT III if you have the bucks and need that rating) and give you an extra margin of safety as well as keeping that nasty utility voltage out of your precious computer case.

An alternative if you can't pop for the high priced 'scope is an isolation transformer - a few hundred kVA line voltage to line voltage.  It keeps your USB scope and computer away from the fault currents of your local distribution system.  

The other pieces are spot-on.  My power supply is a Heathkit triple output unit ca 1978.  Voltage mode only, so I'm often mooning over those current limited units but you use what you have.

According to the Diligent web site their Austrailian distributor is

Their web site does make mention of the Analog Discovery...

David,

No worries, I have come to learn a long time ago that getting emotion across on the internet is sometimes a difficult task. 

 

As for my desk being tidy, well I did clean up a bit before the picture ;)  When I am in the midst of a project, it is not near as clean as you see it there.  This week, I will be getting it a bit dirty as I have 5 boards to solder up to deliver to customers.

Yeah, it looks like they are marketed under the name of Amprobe now.  THey cost a bit more.  I found my device from ebay at close to the original price as what Meterman was selling them.

Adam...just seen yours above about your Meterman DMM.  I got a Meterman RS-232 interface from the bargain bin or a shop here for $5.  It was for a Meterman 38XR meter.  I then got the meter off Ebay for about $50  So I got a really classy meter, with a computer interface, for $55.  Not as small as yours, but as you say they have a lot of features.  I think they have now gone bust, or been taken over (maybe by Wavetek if memory serves me right).  One (more) of my intended projects is to get a PC in my workshop, so to be able to log stuff with it will be very useful.  I found an article somewhere with decodes of the data format, so might be able to do custom stuff.  I also found a VI (software) to interface it to Labview, have not tried that yet though.

Sorry, Adam, hope you didn't take that the wrong way...wasn't meant to be in any way disparaging....I love getting into my workshop (I work in telecomms so like you electronics is not my primary job).  But I'm a hoarder as well and my space tends to get full of stuff - albeit interesting stuff - that I am NOT working on.  I wish I was as tidy as you!  And yes your article has certainly given me food for thought and encouragement to get my act together!
