PING: John Larkin TPS2024

Feb 10, 2014 8 Replies

Hi John,



I seem to remember you having said that you have a TPS2024. When you get a moment could you take a look at the power adapter and see what it's rated at in terms of voltage output and current capability as well as polarity of the connector (I never assume + is the center pin)? I've got a TPS2014 on the way that is coming with no power adapter - replacements from Tek are $500!



Thanks.

Right.

Thanks Lasse.

Found a good sub for 7 bucks on Ebay. Have you ever had to re-build the battery pack or found a good sub? Not sure if the pack is Tek proprietary as I don't have the scope yet, but I'm sure not going to buy this from Tek either as they want $300!

Buy two and take one apart before hooking it up to your nice scope. I'd go for a good quality one instead, if I were you.

Cheers

Agreed. You can buy a nice Phihong one from Digikey for like $30.

The eBay steaming-POS adapter will probably be unsafe and degrade your scope's performance due to noise.

$500! They must pay $10 for it.

Tektronix has lost their minds. Sad.

The picture on Tek's product page

shows a "NI2040" Li-ion battery.

If this is correct, then Inspired Energy is probably the battery supplier:

They claim they will sell quantity 1, but don't list a price. They also mention that they will customize the firmware on the battery for large orders, so it's possible that Tek has custom firmware on theirs, so they can rip you off^W^W^Wprotect their customers.

Interstate Batteries has what they claim is an equivalent battery, their part number MED0088, for $219. It doesn't list a Tektronix part number as equivalent, though. I don't *know* if this battery works in your scope; I just Googled it up. More info at the following hideous URLs:

Apparently this size battery was used in some laptops, so some computer battery places have a knockoff of it. $139 at

Hmm... This may be the source of some of the knockoffs. $189 MSRP, they list retailers on their site. The test button and fuel gauge window look like the one on the Interstate Batteries part.

Again, I haven't plugged any of these batteries into a TPS2024. I just Googled them up.

Standard disclaimers apply: I don't get money or other consideration from any companies mentioned.

Thanks Matt! Some good starting points.
