Ah yes, the "high impedance" *10 1GHz passive probes.
Ah yes, the "high impedance" *10 1GHz passive probes.Their impedance at 1GHz is actually j40 // 10M . Note the irrelevance of the 10M and the lack of zeros in 40 , due to the 4pF tip capacitance For comparison my 1.5GHz *10 HP10020A passive probes (introduced in 1978!) are >j230 // 500 Note the significantly reduced loading due to the <0.7pF tip capacitance
The update rate that does not change is all great, but it's clear that measurements are done on only a small fraction of waveforms.

All that matters is the final measurement update rate, 7 times faster is still 7 times faster, AND you still keep the high update rate for capture as well.
Does it support Ali-pay, Apple pay and Google pay? Tap your phone to have 10 minutes of protocol decoding.

Do we have a 10MHz reference output?
Why do they have the illuminated buttons and also the LEDs next to them? Do they do different things?

A nightmare for all others.
How do you figure? As best I can tell, all the scope makers support time-limited “demos” of individual option licenses. It’s just that right now, their reps can give those out for free for testing, but usually just once or twice before their bosses get mad. I wish they just sold those time-limited licenses so we could just license certain features as needed.

Do they do different things?I think:The button illumination indicates the channel is being displayed on the screen.The LEDs indicate which channel the gain and offset knobs will modify.Regards,Jay_Diddy_B

This would anyway lower the update rate. While did not find any specifications.- How the ENOB on 100uV as may 200uV too will show up and how the noise will be.- The internal reference oscillator PN specifications and nothing about the synthesizer jitter in various time/div- Do we have a 10MHz reference output?- FFT with rtHz scaling, this would knock out many others from Asia
