SPECTRUM ANALYZER

摘要

PURPOSE:To make it possible to measure the frequency and amplitude of each signal in a displayed peak order, by displaying the left or right peak marker of a presently displayed marker position on the signal trace of a picture. CONSTITUTION:An input signal is received and a measuring signal is ouputted by a variable frequency means and digitalized to be stored. This memory signal is displayed in the form of a signal trace and a marker is displayed on said trace and the marker is displayed at the next peak position on the left or right trace of a presently displayed marker position. Therefore, the frequency and amplitude of each signal can be measured in a displayed peak order.
