The whole concept is ridiculous, in (my opinion) a VERY bad way, technically speaking.
Test equipment (in some environments), is used to carefully take accurate readings, which can be used to make very important manufacturing/design decisions. Incorrect results can (in some cases), lead to production failures (mistakes), which can cost businesses fortunes, or even badly damage the companies image.
It might even affect the safety of devices, that are put into production.
So, opening up a (presumably/generally) calibrated test instrument, and making internal modifications. Which could affect the reliability/accuracy/warranty and even safety of any measurements made with the equipment. Is a real big NO NO.
Their marketing department, may think it is an obvious 'joke', but (at least to me), it looks ridiculous.
I can't see how Keysight, expect to be taken seriously as a decent/quality maker of quality/reliable/accurate test equipment, if they make stunts like this.
tl;dr
I'm now seriously worried that the senior technical people at Keysight, don't have the necessary management influence, to produce reliable instruments, if things like that video, get past marketing.
I.e. If someone gave me hundreds of millions of dollars, to buy an aircraft, would I choose Boeing, as the suppler of the aircraft ?
A brand can be damaged, by poor management.
