Your pulse generator arrived today in Germany, thanks for the fast shipment.
One question.
When I run your software on my PC, (Win7), I get weird selection numbers for the voltage selection.
Is it the software or anything I am missing?

It looks like a decimal dot/comma confusion.
Temporary bugfix: for now assume it is in microvolts
I will try to change my locale and see if I can replicate and fix this.

Aww so it doesn't have a secret 2kV output range in select European places? Would be pretty impressive with that rise time.
I'm on vacation so Il know if I got mine once I get back home.
Today mine arrived. I guess my TDS580 wins the prize for the most ringing display
It will be interesting to learn what contributes to the different responses seen on various scopes.
OK, I will wait for you to figure out the decimal point.
Here are my measurements on my slowest scope.
This is an Agilent branded
DSO-X-2002A, 70 MHz
OK, tested on my Agilent
MSO-X-3104A, 1 GHz scope
Rise time 440 ps
The software is running on an older XP
This time I get good numbers like 1000 but if I select a different number, like 1400, the signal is not changing at all.
Now tested on my Agilent
MSO 7045B 500 MHz scope
Rise Time 1.03 ns
No overshoot, may be the scope is too slow!
This time Software running on a Lenovo Laptop with Win7 Pro and all works as expected
Now tested on my Agilent MSO 7045B 500 MHz scope
Rise Time 1.03 ns
No overshoot, may be the scope is too slow!
Don't forget to terminate input to 50R if you want fastest and cleanest risetime.

Now my last scope for this test, a Keysight
MSO-X-6004A, 6 GHz, 50 Ohm
Rise time is 88 ps
Now tested on my Agilent MSO 7045B 500 MHz scope
Rise Time 1.03 ns

You are right, I forgot the 50 Ohm setting.
Here again the same scope, 50 Ohm turned ON
Rise time 630 ps
Just for fun I tested your pulse generator on a 20 year old
Fluke PM3394B, 200 MHz
50 Ohm input
1.84 ns rise time
Now my last scope for this test, a Keysight MSO-X-6004A, 6 GHz, 50 Ohm
Rise time is 88 ps
Assuming total system risetime T
system2 = T
scope2 + T
pulser2It checks out reasonably well:
T
system = 88ps, T
pulser = 50ps
From there T
scope = 72ps
MSO-X-6004A specification lists 75ps risetime.
Pleasant UI on that Fluke.
Neat to see some CROs join in even if they are hybrids.
Oh and do all your scopes have names like that?
Found some time and tried the Wavewhatever MX104 @work

Only on my high voltage bench, Scope-1 to Scope-6 because I am switching the RS232 connection manually to one PC input for data acquisition.
Received mine today, thank you Leo!
Here's my Rigol DS4000 series:
Hi Leo,
News from order 20535?
Hi Leo,
News from order 20535?
Hi Denis,
Shipped on the 20th of July with Airmail.
Thanks
Leo
Mine has arrived, all good. Thanks.
Will have a look at the output on my scopes when I get home from vacation.
Should be there today hopefully. Thks Leo
Today we had a demo of some Tek stuff here.
I managed to get screenshots from the new MSO58 2GHz flagship. This has a frickin large screen - with lots of space for ringing. I believe my TDS580 (see somewhere above) isn't that bad in terms of Tek-ringing. I do still like more the clean edge of the LeCroy.
(first two pictures)
Then there was the fabulous fiber optic isolated probe with 500MHz bandwith - the signal looks a bit different (third picture)
Fforgot to adjust the timebase for the rise time display to work, too many people around distracting me.
Do I see this right, the Tektronix 2GHz MSO58 has 213 ps rise time with this 50ps pulse generator ?

Thtat's what I've seen. The specification (taken from Tek website) is:
Bandwidth (calculated rise time) 350 MHz (1,15 ns), 500 MHz (800 ps), 1 GHz (400 ps), 2 GHz (225 ps)
They must have different frontends for the 2GHz models, since many specs are different between 2GHz and less than 2GHz models.
Hi Leo,
Received mine today as hoped.
Tested on Rigol MSO2302A (300MHz, upgraded...) and Tektronix 2445A (150 MHz). Results as awaited, perfect!
Rigol MSO2302A (300MHz): 1.050ns (rise), 1.090ns (fall)
Tektronix 2445A (150 MHz): 2,00ns (rise), 2,10ns (fall)
The software rose an error when launched: Error '13' uncompatible type (Windows 10).
Thanks again.
