I have not looked at the 8195a specifically
<d1b2>
<azonenberg> @vipqualitypost i'll have a look in a bit. Been super busy lately
<d1b2>
<vipqualitypost> no worry, me too 😄
<d1b2>
<vipqualitypost> the ngscopeclient domain is "too new"? or something? and gets blocked at my work, so I need to remember to bring the manual on a flash drive so i can build it on my work pc

<azonenberg> too new?? lol wut
<d1b2>
<vipqualitypost> no idea lol, it gives me a popup that the registration is too new. i bugged the it guy about it but figure it will never get addressed
<azonenberg>
the domain is almost a year old
<azonenberg>
glad i'n not a new business lol

azonenberg: see the immense field of broken middleware that is configured by people who don't give a crap about wether you can do your job
<Darius>
I do not miss working for a large org, although at least they were dysfunctional enough that my shadow IT setup remained unbroken
<d1b2>
<azonenberg> Lol
<d1b2>
<azonenberg> Yes, I'm glad to be working for a small company. and also in infosec where they are generally pretty hands off about such things because they actually want us to be able to get our jobs done
<d1b2>
<azonenberg> Ok so, i have four more passives to place and a few stitching vias to add then i can get this rubidium clock board ordered, then i have to populate the microkvs test board
<d1b2>
<azonenberg> and then maybe i can have some time to look into recently filed bugs...
<d1b2>
<vipqualitypost> i work for a relatively small company (< 100) but we got acquired and IT is one of those things that they really push on us
<Darius>
azonenberg: which Rubidium are you using?
<Darius>
We've used the PRS-10 at work
<d1b2>
<azonenberg> symmetricom sa.22c from ebay. this is just a quick and dirty test for some other stuff, the GPSDO is intended to be my main lab timebase
<Darius>
ahh right
<Darius>
we use them to make bistatic VHF radars
<d1b2>
<azonenberg> tl;dr i wanted a non-gps locked reference to compare stability of two gpsdo's against
<d1b2>
<azonenberg> (my new SRS FS752 and my old leo bodnar)
<d1b2>
<azonenberg> i can tell the two beat agaisnt each other but not which one is drifting (I assume the leo)
<Darius>
fair enough, we feed them GPS for long term stability then use the output to drive DDSs to generate RF for the radars
<d1b2>
<azonenberg> so i figured if i compare both to a rubidium i can see which one is moving more
<Darius>
The Rb should have better short term stability for you rtest
<d1b2>
<azonenberg> Yeah thats the idea
<d1b2>
<azonenberg> The leo is i think just a TCXO the SRS is a double oven OCXO

azonenberg: i was mostly hoping for the odd chance that somebody came across similar problems, and the 8195a seemed like something u guys might have played with :)

azonenberg: I notice that the manual states that the MSO5/6 series supports USBTMC in hardware, but waveform download doesn't work. If waveform download via USBTMC _was_ working, would it be significantly faster than the other methods?
<dingwat>
i'm about to send an email to our Tek representative :)
<d1b2>
<azonenberg> I have a MSO5 on my bench right now i can check the state of usbtmc on
<d1b2>
<azonenberg> ask to get in on the beta for this. We don't yet have full scopehal-side support for this, it's an active WIP
<d1b2>
<azonenberg> But it's going to outperform usb

ooh ok, I will ask about that, thanks
<d1b2>
<johnsel> Hey@azonenberg question I had, I really like your mechanical design for the trigger crossbar. How did you make it?
<d1b2>
<johnsel> I don't think it was something off the shelf modified, right?
<d1b2>
<azonenberg> So, this is an aluminum 1U extrusion from protocase that i had modified (by them, due to limitations of their cad software) to add rack ears
<d1b2>
<azonenberg> the stock config is 1U in height but earless
<d1b2>
<azonenberg> I am not a fan of it for several reasons
<d1b2>
<azonenberg> the front panel is a little loose since it's only secured to the body of the unit at the extrusion sides, so it can flex and pull away from the body in the middle if tugged slightly
<d1b2>
<azonenberg> you cannot remove the top panel without removing the front or rear panel (which can only be done a limited number of times because they're attached to the extrusions with self-tapping screws)
<d1b2>
<azonenberg> The only reason I used that chassis template is because my PCB designs had mounting holes centered 5mm from the PCB edge
<d1b2>
<azonenberg> which was close enough that I could not use the standard 1U chassis design (which comes with ears stock. and is folded from one piece of sheet metal for 5 sides with a separate top)
<d1b2>
<azonenberg> That is what I plan to use for all of my future designs
<d1b2>
<johnsel> expensive?
<d1b2>
<azonenberg> The version as I did was close to $1K. but that included some hourly engineering work done to add rack ears to the template which lacked them
<d1b2>
<azonenberg> (that also included NRE charges, just like PCBs it goes way down in volume)
<d1b2>
<johnsel> Do you remember the base costs?
<d1b2>
<johnsel> If not no biggie I can do a request for pricing with them
<d1b2>
<johnsel> Just trying to understand what a 19" skeleton goes for
<d1b2>
<azonenberg> ok here we go
<d1b2>
<azonenberg> (this is for the extruded design, the sheet metal-only version i think is cheaper?)
<d1b2>
<azonenberg> base chassis 539.31 @ qty 1
<d1b2>
<johnsel> pre-tax I assume?
<d1b2>
<azonenberg> 70 general order NRE, total of 110 silkscreen NRE for front/rear panel markings
<d1b2>
<azonenberg> 60 for modifying the template to add rack ears
<d1b2>
<azonenberg> (all USD)
<d1b2>
<azonenberg> plus tax and shipping
<d1b2>
<azonenberg> (they're based somewhere in eastern canada, i forget exactly where)
<d1b2>
<johnsel> the silkscreen NRE are the (110?) labels on the chassis?
<d1b2>
<azonenberg> Yeah. It was split up as three separate charges for front panel screen, rear panel screen, and then engineering review/setup
<d1b2>
<azonenberg> but added up to 110 for all of the printing on front and rear faces
<d1b2>
<azonenberg> they offer a lot of different options for markings including laser engraving, full color inkjet, monochrome silkscreen, multi color silkscreen, etc
<d1b2>
<azonenberg> so costs will vary by what you choose
<d1b2>
<johnsel> oh okay 70 + 110 + 60 on top of the 540 for the modifications
<d1b2>
<johnsel> did you have custom drilling holes or such?
<d1b2>
<azonenberg> 60 was for the adding ears
<d1b2>
<azonenberg> 70+110 was NRE fees
<d1b2>
<johnsel> yeah let me rephrase 180 NRE/silkscreen customization costs then
<d1b2>
<johnsel> although some NRE probably should be attributed to the ears, but sure
<d1b2>
<azonenberg> the 540 was the per-unit production cost, which drops way down in volume. That included all of the machining work (drilling holes for connectors, adding pemnuts for PCB standoffs) as well as blue powder coating
<d1b2>
<johnsel> roughly speaking
<d1b2>
<johnsel> Oh okay, that's good to understand
<d1b2>
<azonenberg> They offer a bunch of different surface finishes ranging from bare metal to powder coating to anodizing
<d1b2>
<azonenberg> for colored finishes they stock a menu of standard colors as the lowest cost option, or will mix to spec for an extra charge
<d1b2>
<johnsel> Sure those are pretty standard "metal-working shop" methods
<d1b2>
<azonenberg> Yep
<d1b2>
<azonenberg> if you use their cad software they also have a menu of standard mounting hardware like pemnuts/studs in various materials that you can add to the design
<d1b2>
<azonenberg> some are stock, others are non-stock and cost more / have longer lead time
<d1b2>
<azonenberg> My recollection is i probably could have cut something like 100-200 USD off the order cost if I had gone with a standard sheet metal template rather than the aluminum extrusion version
<d1b2>
<azonenberg> between the template costing less and not needing the ears to be added
