My 1 remaining client is in the market for some new scopes. Their old Tek 2445 etc have been hammered hard over the years and are long overdue for replacement. They didn't know about Rigol until I told them today and were gobsmacked when they had a look. I reckon they will get a couple of DS1054Z (pocket money prices if you're a commercial customer) plus a top of the range such as this 1GHz beast at half the price of a comparable Tek: https://www.rigol-uk.co.uk/Rigol-DS6104-...ds6104.htm
I look at my one and only DSO, a Tek TDS210, about £800 when I bought it some years ago and think how far things have advanced. Mind you, I've done some good work with it. It's got a fast timebase (5ns/div) for a 60MHz scope which has allowed me to do absolute determination of SCH in PAL signals. This is the subcarrier to H timing phase relationship which needs 5ns/div, triggered every 160ms. I have done this with extreme difficulty on my 2465B but it's black out the room and cloth over head stuff. A 2467 microchannel plate scope would probably do it but I don't have one. Since I'm doing the measurement on my own designs of generators it's no problem generating the relevant trigger signals and frigging the PAL waveform so that subcarrier is present at the F1L1 timing datum.
I've also used it for slow moving stuff, occasionally in conjunction with a Tek 5110 low BW mainframe to get ultra high sensitivity, down to 50uV/div differential.
PS: Minor gripe about Telonic/Rigol. They emailed the invoice today as a PDF. But the attachment was called winmail.dat. Change the filename and it works but it doesn't make them look efficient.
