with the pay of engineers and how much voodoo they are expected to push and evaluate for clueless bureaucrats the scope price is absolutely justified. Sometimes you get 1 day to have to confidently give the answer to a question which can effect a quarter and a entire sales plan for people that make many millions every month and effect an entire work force.

This goes for test equipment in general. If been in situations where a bug in a piece of B-brand equipment caused a couple of weeks of delay and impacted an important demo.

coppercone2:
but the scope is going to be the one that makes the picture that someone non technical can understand

the other instruments make tables, then they think you are buying expensive furniture, and the spectrum analyzer is not in english (that graph is in ancient egyptian). you don't want to explain the signal power within a bandwidth, ever. how come the signal is not moving?

analityk:
I've worked some time for client from Gas and oil industry and from this point of view everything in this film is true.
If in some test procedures some engineer point they use fluke 87 there is always "or equivalent" device and you are free to use siglent as long as it have actual 'papers'.

And point out with buying laptop for 20k with fronted worth 2k is gold. If Tek can use Windows on frontline and most important scopes why military can not? It obvious. Tek scope are not need be so reliable as military grade device.

Point out with industrial components. There is a few temp. grades category where manufacturers can specified some parameters that will always be in some range. There is also reliability test and data you can study during finding out a new components. But it make senses when you want to sold fucktylion devices. Then MTTF, MTBF and FMECA, which one scope manufacturers do FMECA... BS. Maybe Tek or other overpriced scopes use industrial grade device but it doesn't make sense. Show me your Tek spec and temp range where you can use them. -25 to +85 degree of Celsius? Show me this LCD working under -25 C.

Approvals chain is where the time is wasted, good bosses have found smooth ways to avoid that and fit for purpose stuff just gets bought. Cheap things like a Uni-T meter would disappear from oversight through low value or stuffing it within a larger order.

That is my experience as well. If the cost is below a certain arbitrary threshold you can get anything. Above this, if a product is from one of the non-traditional companies, be prepared to back it up with technical and long term maintenance reports to justify the purchase.

I have seen this lack of willingness to purchase the right equipment hamper development for quite some time. Add to this the engineers' time, RTM delay and other factors, and the initial ~$100k capex was easily offset.

OTOH, I also have saved weeks of troubleshooting by using my personally-owned Rigol DS4014 and its deep memory instead of the ancient Tek TDS3054s or Agilent DSO6054As available at work.
