The Keysight 70861A contains new firmware loaded into a high speed ROM/RAM board that plugs into the Keysight 70900A/B. You can transfer data directly to a disk. The firmware allows the spectrum analyzer to read and write to external disks. No computer is required. You can save and recall traces, states, downloadable programs (DLPs), and limit lines. Simply indicate the storage device desired: memory card, external disk, or internal memory (32 KB).
Extract information from complex modulated signals, such as TV, pulsed RF, and FM. Digital persistence simulates the variable intensities of analog displays, without sacrificing the storage and plotting capabilities of digital displays.
