From the ad:
"The UTC oscilloscope incorporating the new 24-XH 2" cathode ray tube has every feature required for application in the radio field. It includes linear sweep, audio amplification, brilliance, focus, beam centering and amplitude controls. Grouping of the controls on the simple control panel is such that rapid and simple adjustment is possible.
The entire unit is housed in a black crystal finished carrying case with etched aluminum front panel. The size of this unit is extremely small considering the 2' cathode ray tube and multiplicity of applications."
