General Description of the Compact Digital Ionospheric Sounder Digisonde 256. Revised
Abstract
After the technical and operational success of the earlier digital ionosondes the new Digisonde 256 concept was chosen to combine the simplicity of the Standard Digital Ionosonde DGS 128P with the flexibility and the fast preprocessing speed of the Universal Digisonde 128PS. Contained in a standard 7- inch high chassis in Digisonde 256 includes a precise and fast digital frequency synthesizer, a transceiver for the frequency range from 4.0 to 30 MHz with front-end tuning, a high-speed digitizer, a versatile multichannel complex spectrum analyzer and a complete timing unit. These subsystems are controlled by a built-in front-end microcomputer to optimize and format the data for display and recording on magnetic tape and hard copy. Necessary peripheral equipment are a thermal dot printer and a wide-band pulse transmitter, while the 2 x 7 antenna switch, the magnetic tape recorder, the plasma display, and a post-processing computer for automatic ionogram scaling are considered optional peripherals.
