What hell have I unleashed......

I secured the space for my 12U rack case.  It now occupies that space and I am still alive to tell the tale.  I have fitted the 8656 in the top spot, then started looking at the placement of other bits of kit - and there is not going to be enough room for what I would like to set out.   :palm:  (My aspirations outgrew my planning ...  ;D  )

My casual reference to modification of the hob on my desk is now an official necessity and my ideas on setting out a storage solution for tools that will allow easy access has now become a critical design and construction project.


I've stepped in a puddle and sunk down to my eyeballs.  Someone toss me a snorkel.

A snorkel...   :-DD :-DD :-DD

Snort...  Someone toss him an 8566B!   >:D

Back in case and started burn-in #5. Must go at least 4 hours before calling it a done deal. Nice sharp trace almost rivals the bad boy 485 to the upper left.  ;D The 2430 lower left is a noisy DSO. Not even in the same league.  >:D

Well my RS delivery arrived finally. Third day lucky. A3 cutting board and one resistor. Resistor is good. Cutting board is a piece of shit. Supposed to be self-healing but it isn't. Two cuts and it is ruined  :--. Phoned up and whined to RS and they just refunded it  :-DD

So:

RS Pro = piece of shit. tautech - all siglent stuff has that branding from RS. I'd call them up and tell them to stop wiping poop on your brand  :-DD
RS delivery = piece of shit.
RS service = pretty good.

Perhaps BD is a little bit frightened for some reasons, because Santa Claus (not the guy from Coca Cola)
is coming to town today to reward the good kids and punish the bad ones.


Not sure which category some of you will go.  >:D  :-DD

That's rather advanced WiFi integration for the RCA.

Quick experiment. Introducing the "POS load". Roughly speaking, does a single Caddock 30W 50R resistor on the end of a bit of RG174 make a half decent dummy load or is it a piece of crap?

Desired outcome: pretty low VSWR up to 20m band. Anything else is a further win.

Test results:



Data:

7.1MHz ->  1.05:1
14.1MHz -> 1.1:1

Good enough  :-+

Now to upscale to 200W

My name is Saskia and I have a habit.

It all started when I rediscovered Arcade and Pinball machines and found Louis Rossman's channel on youtube.

I started with that UT139C and an old Weller iron. After a while I decided that visiting the Reichelt store seemed to be a good idea. This is when I started rummaging through their returns pile that they put up heavily discounted.
Louis got me hooked on Hakko and Quick 861, and soon my first Agilent DMM made it into the stockpile (an old 1252a). Soon after an Agilent LCR popped up, followed by a Fluke 114 which I found at Reichelt, followed by yet another Agilent DMM, a couple of entry level oscilloscopes, and finally some boat anchor ...

885388-0

Having secured that I am still trying to integrate this into my rather small workspace

885380-1

and then it happened.
I got an invitation to a Keysight event and decided to attend. In the coffee break they asked me if I had any use for additional test equipment and I told them that I just got a quote from R&S regarding the RTC1002 and the RTB2004 and was wondering which one to buy. They said that they wanted to accomodate me and pulled some strings, which resulted in my buying this:

885384-2


Aw gawd, I never thought such a device would have a 500 pages plus manual ...
Now I am waiting for my diff probe (thanks Dave for supporting my habit :) which DHL failed to deliver.
Hrmpf. One more day of waiting before I can repair my husbands Volvo ...

Anyway. A stockpile of equipment and an even bigger stockpile of pinball machines to fix. Sigh.

I think I need a bigger flat ...

@Saskia

Welcome to the TEA part(y) of the eevblog forum. Hope, you'll have a good time and don't be afraid of all the inhabitants here, they're mostly harmless.

The RCA 54-45 scope failed burn-in again...for the 4th time. This time the trace went out of focus. Little or no focus control. 5 minute find and fix. See schematic. R20 (4.7M) went open. I've seen that before in CRT focus circuits. Seems those high value carbon comp resistors don't like HV placed across them. I replaced it with two 2.2M resistors in series to spread out the voltage drop.
Me too.
Yep, almost as bad as tants !  :scared:

I am somewhat offended by that remark!  :-DD   Everybody else... be on your best behaviour; at least TRY not to be overwhelmed by the girl fumes.  :-DD

But... med, are all of us grumpy old men?
No, some of us^W I have even 23 years to go (to work every working day) until retirement (based on current regulations)..   :P

Edit: I've got 23 working life years in front of me, not 33.  :palm:
