I. General For years the professionals have been using spectrum display units(SDU) and spectrum analyzers as an aid to intercepting those elusive signals. Now the serious listener can afford to have the luxury of an SDU with features never before offered in this type of equipment. You will be able to watch up to a 10MHz window of the spectrum. By moving the SDU cursor left or right, or Pressing 1PEAf 1 key, you can pinpoint a signal of interest and instantly read frequency and signal level while listening. This new feature is possible using the AR-3000A general coverage receiver, and all data can be stored on disk for later analysis when a PC is used. II.
