Spectrum analyser automatic scale search: One step ahead in automation

TV EXPLORER users have considered that the control of the spectrum analyser based in the four arrow keys is a very valuable innovative function. The goal was to add as much automation as possible in the meter’s user interface to make technicians job faster. Continuing on with this philosophy PROMAX wanted to offer more in the TV EXPLORER II and TV EXPLORER II+. The reference level in the spectrum analyser function is initially set automatically to the best value based on the power of the signal shown.

The reference level is instantly adjusted by the TV EXPLORER II / II+ as we enter the spectrum analyser function. The graphic shown is then ready to be anlaysed with all its ups and downs with no additional key strokes.
