Not wanting to look like I was bought but aside from Tek, I don't look for much innovation. When Tek hyped the 5-Series announcement, I stayed up the night of the unveiling to get first info from the New Zealand event.
My sources for announcements are Vendor and Disti promotional emails, Electronic Products and other EMag websites. For datasheets on scopes to 4/6 GHz, one of my favorite go-to's is TestEquity. Their web layout is efficient and nearly excellent when you get to product pages for pricing, datasheets and options. I go to vendor sites to fill in the blanks. One of the things I distinctly "don't like" is what Tek does too often by trading information for a prospects vital details to allow sales follow-up. You've even followed my browsing of your site which I discovered through followup calls from sales.
By the way, there was a topic from a user who had narrowed his selection of a scope to 3 suppliers on this forum. I was surprised at the lack of methodology in choosing a scope from those who replied. Instead, people went off on tangents like screen refresh rate, etc. We can and should do better.
If you're wondering which places to target for new products, I'm encouraged because your product line is weak as if your R&D budget did not survive changes in ownership. When the MSO4000, 3000 and 2000, MSO5000 and MDO products were coming out times were great up to 2GHz and innovation was on a high note. But those looking for 2-8GHz may have strayed to Keysight for their newer designs in that range.
In your defense, I am totally into the 5 Series but wonder if you can take that architecture above 2 GHz due to the increasing cost per channel x 6 or 8 channel variants. Below 500MHz, things could get interesting with the architecture and the opportunity for chip count reduction at lower speeds.
Sorry this turned into a rant. I'm an Applications Engineering / Technical Marketing / Engineering Manager kind of guy for semiconductors but always really admired oscilloscopes in general and Tek in particular. Get moving!
