I'm the happy buyer of 2 of these boards but due to real life implications it will take time to do a deep dive into the boards.

I'm a silent reader of the TEA topic because I'm sure I do not suffer from TEA  :-DD

To avoid any infection with TEA I started selling some old unused equipment during the last year and I do not have any interest in boat anchors.

In the last 12 month I bought only a new SIGLENT SDG2104X+, a HP 34401a DMM, a HP 53131a counter, a SIGLENT SDG2042X, a RIDEN 6018 PSU, a Uni-T 612 LCR meter, a Uni-T UT181A multimeter because of
the great display, a dozen OCXOs, 2 GPSDO (SAMSUNG and SYMMETRICOM), a bunch of 5 video distribution amplifiers for 10 MHz distribution, some other GPOS stuff and about 50...70 little grey bags from China arrived.

And I'm with Tony Albus, I have the strong gut feeling that it's time for a Siglent SAA3021X+ ...  No, I'm not infected.... |O

Why did the RAF purchase the C17 and the Airbus A400M? Don't they basically fulfill overlapping roles?
Yes they do to an extent, but they both have different load capacity and operational requirements. The C17 has the largest load space and can carry 69 tons while the A400M carries has a smaller hold and can manage 37 tons and so the A400M is the more resourceful for those seeking to transport items to dangerous locations because of the risk of sucking dirt into the engines on unmade surfaces with the jet engines of the C17.

I believe, but have not checked, that props give better thrust at low airspeed, which is advantageous for quick steep departures.

Of course if you put a big enough engine on it, you can make bricks and lawnmowers fly.
There are lies, damned lies, statistics - and ADC/DAC specs.

Its 24degC outside, I'm drinking a Harp and doing BBQ. Life is good  :-+



Commiserations on it being Harp.  :)

Can you really still get that stuff? I haven't seen that on a pump or even in a can in the UK for years. Given the swill that a worrying number of Britons will drink under the label "lager" it might be surprising that we've given it the cold shoulder, but that we have.

Poms used to drink the most godawful crud------Watney's "Red", anyone?
The absolutely worst that I ever drank was called "Alsopp's" lager, which came in a sickly yellow can, predicting the contents.

The Chandris line ships used to stock up on whatever they got cheapest, from Alsopp's as the worst, through decreasing levels of awfulness, via "Fix"(arrrgghh!), Courage lager (Blecchh!), up to reasonable to good (Oranjeboom, Beck's, VB, etc.).

Coming off the ship in the UK, we were confronted mainly by a desolate waste on the beer front, with a few tolerable, like the aforementioned "Harp", Carling black label, Newcastle Brown, "Ewer's Lager" from Scotland, & a few others.

That was, of course, in the bad old days, pre the "Real Ale" movement!

Woaa, so many beer snobs. I guess I'm not going to tell you what I drink in term of wine and where I get it.  :-DD

That's not beer snobbery, it is merely having a little good taste and discrimination.

A wine importer once made the wise observation that the only generalisation you can make about wine is that the more you drink the better it gets.

Hey, we won't judge, unless you tell us it's white, comes from Canadian Tire in gallon plastic containers, and would go down well with a certain generation of Austrians.  :)

Those Austrians prefer blue wine, i.e. https://en.wikipedia.org/wiki/1985_diethylene_glycol_wine_scandal

More OCXO shenanigans.

Decided to give one of the OCXOs a winter overcoat and see how it performs in that. So, a nice warm jacket made of closed cell polyethylene foam (the kind that truly careful equipment packaging is made from). The OCXO's the right way up this time, insulated on all sides and the leads led out of holes made in the bottom of the foam with a bit of stainless steel wire heated up on the gas stove. Agains, a little uncalibrated 100k NTC bead thermistor taped to the OCXO. Taped to the underside this time, theory being that I'd mount an SMD thermistor on the board to monitor the OCXO temperature in its final resting place. Given the mechanical as well as thermal sensitivity of crystals, it strikes me that this might not be too bad a way of mounting the crystal anyway.

So, tailoring:



Warm up curve:



Section from the last half hour of monitoring where the temperature curve is essentially flat, with a different scale so we can see what the variation is once it's 'stable'.



d(temp)/dt plotted as well with both to get a feel for rates of change, stability, and noise in the temperature measurements. I'm thinking of using d(temp)/dt as a way of detecting that the OCXO has reached a comfortably stable operating condition, so I want to see the temperature derivative for that reason too.

Hi Ceberus,

during the last year I also played with different OCXO solutions for GPSDOs. I learned that it's better not to cover the OCXOs with foam because the heating-cooling-regulation needs the convection with free air.
It only makes sense to avoid direct air flow from a vent. All the professional solutions I have seen use the "naked" OCXO.

I have done this only one time since I had a OCXO without Vref output and I used a cheap TL431 for this. I put it at the can of the OCXO and covered it with foam.

The RAF have the highest hours C17 airframes. As they are getting rid of the C130Js  :-// in 2023 the C17s and the A400Ms are going to be flying a lot more hours.

It's not strictly a DMM, it's a DC Voltmeter. No resistance, current or ACV measurement and that's quite a chunk of cash to spend just for DC voltage.

Just in case you have some cash left after that Comodore64  ;D and want some of these analogue boards, here are the last "anti-hoarding" links:

The one who receives it first should creat a topic about "dissecting" and reversing the devices, I will gladly participate, congrats to Ulrich (no connection with the seller) and that was it.

 Cheers,

I'm the happy buyer of 2 of these boards but due to real life implications it will take time to do a deep dive into the boards.

I'm a silent reader of the TEA topic because I'm sure I do not suffer from TEA  :-DD

To avoid any infection with TEA I started selling some old unused equipment during the last year and I do not have any interest in boat anchors.

In the last 12 month I bought only a new SIGLENT SDG2104X+, a HP 34401a DMM, a HP 53131a counter, a SIGLENT SDG2042X, a RIDEN 6018 PSU, a Uni-T 612 LCR meter, a Uni-T UT181A multimeter because of
the great display, a dozen OCXOs, 2 GPSDO (SAMSUNG and SYMMETRICOM), a bunch of 5 video distribution amplifiers for 10 MHz distribution, some other GPOS stuff and about 50...70 little grey bags from China arrived.

And I'm with Tony Albus, I have the strong gut feeling that it's time for a Siglent SAA3021X+ ...  No, I'm not infected.... |O

My two (+connectors) have just arrived, so you won't have to wait long, the only big problem is the topic name and where to place it and let the fun begin  ^-^.
Also, nice stash/stack of TE, but that does not make you an addict, no sireee, just mildly interested  >:D.

 Cheers,

And today I see the specialist. Hopefully a definitive plan of action to get me fixed up will be established and implemented.  :-//

My views coincide with Bad_Drivers.

No heavy boat anchors but interesting developments.
And repairable modern equipment.
I also bought 2 boards.
For TEK I make the usual exception.

DC1MC, I appreciate your approach to volt-nuttery.

I forgot the connectors - shit! btw: a very nice EBay seller.

It took 15 minutes to make the decision for the second board and I paid 2x delivery but the seller
send one postage back to my Paypal account - very kind!

Feel free to open a new topic but plz give me a link. May be the work on this reference board makes it necessary
to buy a new/better/second DMM .... :=\

I was a year or so in time- nuttery... now with about +/-1ns (to Universal Time) it's ok for me...

Hi Frans,

to my regret, no, I don't.
I received today a newsletter from Instrumex where the Hioki has been mentioned.
I got curious and looked out for more details and then I've posted it here.

That's all.

As far as I understand, it is a digital voltmeter, especially dedicated for measuring Li-Ion-batteries.
"The Hioki DM7276 7.5 digit DC Voltmeter, delivering high measurement accuracy of 9 ppm, is ideal for development and manufacture of lithium-ion batteries."

Here you can find some pdf files about this Hioki DM7276:
https://www.calplus.de/hioki-dm7276-01.html

Edit:
Added the direct links to the pdf files:

HIOKI DM7275, DM7276 - datasheet english
Hioki product overview - Test equipment for batteries english

Hioki DM7275, DM7276 - Manual english

Application notes:
Effect of the measurement target output resistance and voltmeter input resistance on measured values
Measurement of the package potential of laminated lithium-ion batteries

Why did the RAF purchase the C17 and the Airbus A400M? Don't they basically fulfill overlapping roles?
Yes they do to an extent, but they both have different load capacity and operational requirements. The C17 has the largest load space and can carry 69 tons while the A400M carries has a smaller hold and can manage 37 tons and so the A400M is the more resourceful for those seeking to transport items to dangerous locations because of the risk of sucking dirt into the engines on unmade surfaces with the jet engines of the C17.

I believe, but have not checked, that props give better thrust at low airspeed, which is advantageous for quick steep departures.

Of course if you put a big enough engine on it, you can make bricks and lawnmowers fly.
Well, according to my son who is the expert in these matters, the RAF purchased the C17's as a stop gap while waiting for the A400M to be delivered. They were so impressed with the C17 that they purchased more of them and when the A400M was finally delivered, it was as not good as the C17 and is proving to be too complicated and thus unreliable in service.

Not bad, That part number has slightly poorer ambient temperature stability < 7.0 x 10-9 from 0° C to +71°C rather than the < 4.5 x 10-9 from 0° C to +71°C of the standard model.

PSA: In case you have some low / medium power application, and you would like to have an variable in series power limiting device (think 5W low-ohms wirewound potentiometer) - but your stash lacks said device? I came across and tested a nice simple solution, based on "rubber diode" / "VBE multiplier" like it is used in biasing of push-pull audio power stages, but with slight variation. Please find schematic attached. It works with low power potentiometer ~10k. The maximum voltage drop across can be set and depends on low power NPN Q1, potentiometer value and R3. Minimum drop is ~0.8V. Dissipation is limited by heatsink and power of PNP Q2. Have fun!

They actually leased the C17's initally, then bought them and some more.
