Title: oscilloscope Model question
Post by: Plasmah77 on May 29, 2010, 10:54:06 pm
Hi all I'm a newbie here.

I have my first question:

Whats the difference between these two models TEKTRONIX 2215 and the 2215A?

I won a 2215a on ebay and just wanted to know what the A in the model# meant.

Thanks

Jim

According to http://www.testequipmentdepot.com/usedequipment/tektronix/oscilloscopes/2215a.htm (http://www.testequipmentdepot.com/usedequipment/tektronix/oscilloscopes/2215a.htm)
"Same specifications as 2215 with improved CRT intensity and bandwidth limit"

Often an A revision is just an upgraded model internally (new construction and BOM), with very little or no major spec differences.

The 2215 is a nice and solid basic scope.

Well thanks to you sir.

I actually almost bought a DSO Nano as my first scope until I watched your Youtube video ;)

Thanks so much for steering me in the right direction.

A wise choice!

I've gotten quite a bit of backlash from defenders of the DSO nano pointing out all sorts of niche benefits and how wonderfully cool and handy it is. They are so missing the entire point, it's rather humorous!

You're lucky the dso nano isn't open source Dave, they'd be outside your house with pitchforks ;)

The hardware and most of the firmware for the DSO nano IS open source!
I already get hate mail, it cracks me up!

Criticizing open source anything is like criticizing someone's child. Except this "child" has many many parents all over the world. This creates a mob mentality.

If you really want pitch forks outside your home, just point out that the GPL borrows from the marxist philosophy of communal ownership. Although that would amount to trolling at the worst possible level.

Ahh well in that case we better keep an eye on dave til it cools off, or send him more GPL'd hardware to test  ;)
