Test and Measurement at the 2013 NAB Show
The first time a new acquisition format
appears at the NAB Show, it
draws a crowd of curious onlookers.

the new format, the curiosity stage has
been replaced by real-world production in
the new higher level.
This year it was obvious that 4K had
arrived—several manufacturers displayed
4K-capable test and measurement gear.
Of course, there was a wide variety of
test and measurement products for every
other professional television application,
