Am I the only bothered by the tagline “Now you can tell time and measure current on the go.” ?
An oscilloscope measures voltage, not current.

Tech journalism in 2023. No one cares about facts. You should be happy they didn't write "you can measure blockchain" or "you can measure AI" with it. (Yet)
They could have done a lot worse for sure ;)
"Track your potential while staying current" would be more apt
Oscilloscopes measure current too. Differential measurement across a resistor (channel b subtracted from channel a) will result in a current measurement. Also current probes do exist - I own two.
Tell me you’ve never measured current with an oscilloscope without telling me that you’ve never measured current with an oscilloscope.
Hahaha you’re actually right, I bought my first scope a couple of weeks ago. But the primary mode of operation is voltage rather than current. It’s a bit like saying a thermometer is used to measure altitude.
No, not quite. It is actually impossible to measure a voltage without any current flow, ever so slight but it is always there. It is perfectly possible to measure temperature and altitude entirely independently of each other.
My grasp on electricity is elementary, but as I understand it: measuring current in a circuit with a scope is always done via a conversion to a voltage, because that is what the scope is designed to measure. So the current is always derived from a measured voltage.
With my silly thermometer example I meant: you can boil water, measure the temperature and derive the atmospheric pressure and altitude. Should have probably worded that clearer.
Edit: and yes I understand what you are saying. Internally the scope measures voltage using the current that’s flowing across something with a very high resistance.
No problem, first coffee still has to kick in :)
And good morning to you.
Well, at least they got close. It's one of those 'headlines about things you know something about' things.
