Test Equipment Anonymous (TEA) group therapy thread

Yeah the duraplug line is nice, impact resistant.

I like a nice metal housing rack mount distribution strip myself, though they are so expensive I have to take what I can get, recovered from surplus equipment rather than buying them.

I've never been a fan of those TBH, seen to many of those warp making it very difficult to get the plug to engage correctly due to the shutters jamming up.

Good grief, how do you warp those?

Tell the T101's they aren't allowed to plug themselves in!

[Specmaster]

I have been running Data over Power to the shack (30m+) for the last few years but still WiFi for distribution when it gets here to 6 or 7 devices (only 1-2 use any real data quantity). I gave up with WiFi range extenders and aerials very quickly.

Call me a Blended Family 

Yeah, I also use data over power because SWMBO hates wires everywhere and as the real heavy users of data are all concentrated upstairs, I had the internet intake connected to my sons bedroom, from there I took Ethernet via the loft into my small lab, next to his room, into a 16way Gigabit switch  with drops from there to my various bits of kit and another link from the switch via the loft to my other sons bedroom, 2 rooms further along. There it goes into a 10way 100/10 switch and feeds out to his various GC's and PC's plus his own router.

Where the data comes in, it goes to a router, from there into a data over power adaptor, round to the other side of his room, 25ft and exits via another data over power adaptor into his PC. His smart TV and games consol are WiFi to the router (he also hates wires). Data over power down stairs to the TV cabinet, into another 10 way 100/10 hub to connect to smart TV, Internet radio / music streamer, WiFi repeater, Tivio box and BluRay player.

Where ever connected via copper (except in my lab) we get 95/34 and only I get 552/34.

It set the packaging on fire with impressive speed, and will happily make holes in about anything that will fit between the electrodes...
 


@mnem, since you seem to always have your snout in some not-quite-new pc or other, I'm asking your advice; which will give better results, dvi to hdmi, or dp to hdmi adaptor?

Got the DG822 and my word it's one ugly motherfucker. It is however refreshingly silent.



Checked 0dBm amplitude and it's spot on. UI is, err, actually not as bad as I thought. Just need to get through the "who moved my cheese" phase after using DG1022Z's for a bit.

Gah, Wi-Fi, give me a copper network any day of the week, wipes the arse of Wi-Fi. Sitting at my bench, with the router sitting just 4 metres away I get 28/8 on Wi-Fi but wired I get 552/34, different leagues.

My 5 Cisco 2702 access points with WLC in VMWare are quite a bit faster than that ;-)  But, yes, I'd go for cable anyway, so the 10GE upgrade for the internal backbone is going to happen when the family allow me downtime. Interruptions in access to videos and online gaming are business critical issues here...

Oh, and copper won't do. I've got single mode fibre for all backbone links.

Indeed. It's what happens when your company gets big enough to get a design team in. This is immediately after the HR team hires the design team.

First you get the DG822 "A manta ray fish has been sexually assaulted by an Eagle from Space 1999".

Then several years later:

Its actually much bigger than I thought it would be, not much smaller than your scope  As to its appearance, well its all been said before, but at the end of the day its all about its performance after all is said and done

I'm sure it's a fine generator, but are you going to design and 3D print an adapter plate so you can set your coffee cup on top of it?

Depends. If a very expensive GPU, definitely zap the fuck out of all DisplayPorts with extreme prejudice FIRST. DisplayPort connects direct to the GPU so it can provide full HDCP and high refresh rate up to 4K (now 8K, I understand) high BW video. DVI is usually buffered by a scan-converter chip so it can also deliver analog VGA with the correct adapter. 

THEN... if you haven't been discovered... you can nuke the video ports on the MB, then USB ports. Ethernet ports are pretty well hardened against HV; and it's easy to get around a fried one: Just let it run until the chip melts itself off the MB, then plug a NIC in a PCIE slot. Even if you are successful in killing the MB, it can usually be replaced cheaply and Ram/Processor recycled so not a lot of real destruction for your efforts.

If it's an APU-based workstation, you should consider very carefully: Using that machine is an ongoing daily punishment; killing it with that pocket TASER MAY be doing your victim a favor.

yeah, i don’t care so much about what it looks like... price/performance is good. but the ifc is a freakin awful combination of buttons and touch screen and the touch screen itself is clumsy at best.

but then, i (and most folks in this thread) am generally spoiled by regular contact with older high quality TE, right?  i mean, this is the place where people talk about “low emf” connectors.  *laugh*

Smurfizing it actually looks better. Although when you drop dead one day and it ends up on ebay someone is going to be very very confused

Hahaha  . Yeah it's not suited to placement of dangerous fluids unfortunately out of the box. That reminds me of the 33120A I had with suspicious looking coffee stains down its bum.

It's not great. The whole push the channel touch screen, menu / home, encoder thing is like using some VBA application written by a 6th form student. I'm programming myself to use it because it was cheap, fast and accurate for the cash.

Now looking at an SDS1202X-E

Edit: this fail up is why I needed it among other use cases ... 1.5KHz filter config right out and the BFO is all over the place. So -53dBm out via 20dB attenuator straight into the antenna port gives you a S9 signal on the radio stable enough to unfrig this mess.

Come on, man... I have a wife & kids with all their smartpwns, iPuds, faptops and random bits of IoT buggery. If I tried to force them all into ONLY hardline-capable devices, they'd Zergling rush my fat ass and hang me up by my nutsack in a tree until I came to my senses. 

I picked this up at the Thrift because A) CAD$7 & 2) similar to the one in my living room owned by Rogers Communication, so curious about what is inside & whether it can run OPEN-WRT (appears no...  ) or at least maybe configured to serve VPN to the whole house.

Tearing it down, I find this is actually an impressive little machine. Proper 3x3 2.4GHz & 4x4 5GHz MIMO antenna array with separate radio modules for each. Lookit that massive heat-sink sandwich! RF and DOCSIS modules connect to the backplane via mini-PCIe slots and 4 GBe ports, one which is labeled as console, so hopefully WiFi admin access is hardened out, or at least possible to disable.  On top of that, built-in 60W PSU instead of wall-wart, and a cooling-tower flow-through design for heat-dissipation on those nice big heatsinks.

And... if you look just below the CPU, you'll see two (JTAG?) programming headers labeled ATOM & ARM depending on the CPU installed.

Honestly this is a helluva little piece of hardware; the only thing wrong with it is... ISP-designed software.

LMAO at the thought of a dwagon being suspended by his nutsack  .

Hmm, I never said you had to have a wired system, hell does anybody rely on just a wired system at homes these days  I know only too well just how much w
ireless gear you have in your household, but its only advantage is its sheer convenience, it sure as hell is no speed demon, even if he is as red as the Welsh dwagon
