add me to the day one of use RTB2K-COM4 Gen sweep/arb trigger feature request - testequity was way slow to receive, ship 2nd batch

but certainly a lot to like at intro offer $2080

great list. I would like to add one thing that really annoys me since the day I took my scope out of the box: trigger on the sweep of the signal generator.

This is something that was highlighted internally pretty early on, so hopefully will be addressed soon.

Thanks for the info - was mainly interested in confirming that it was well under 1ns. The fast rise time is certainly useful - benefits definitely outweigh the drawback of needing a proper ground (if anything it teaches the user a lesson in good grounding :P)

On another note, did you ever find out about how the fan noise/speed control is meant to work in the RTB series? It was mentioned a while back - it seems that some users find their units very quiet, but others (unfortunately I'm among them) find theirs far from it. It's not a disaster, just strange that some find it quiet, some not, and I'd like to know if there is a problem or if it's just variability in the fan itself (or user's ears/noisy lab environment!). Note that it seems that the fan is running at full speed or close to it, rather than under thermal control.

Hi Hydron - I thought I had replied to this but clearly I hadn't - sorry about that.  The fan is temperature controlled - if it is consistently running at full speed it would need to go in for service to fix that.

Hi, i am looking to buy a multimeter,
any chance you will update the HMC8012 firmware to have "duty cycle display" in the future ?
thanks

Hi JanJansen - unfortunately, I'm not sure as I'm only focused on scopes.

Sorry I can't be more help.

The Electrician:

--- Quote from: Rich@RohdeScopesUSA on June 12, 2017, 07:16:53 am ---Hi Hydron and The Electrician - for both the RTB2000 and the RTO1000/2000 the probe compensation signal's rise-time is quite fast (100s of picoseconds vs most scopes are typically 10s of nanoseconds).  We don't spec it but I'll see if I can find out the exact rise-time. 

There are benefits and drawbacks to a fast rise-time on the probe comp signal.  If you use the typical alligator clip ground, you'll see ringing caused by the inductance of the extended ground lead (drawback).  But the benefit of the fast rise-time is it allows us to provide a high-frequency adjustment to the probes when you use the short spring clip ground (or on the RTB2000 it has a very elegant way of doing the probe comp with no ground accessory needed).

Hope this helps.

Rich,

   Did you ever find out from the factory (or wherever) what the rise time is?
