  • Page 37: Useful Information

    ──────────────────────────────────────────────────── Useful Information 1. About the function keys (1) Memory function Stores A/D-converted data in the memory for each sampling operation. Changing the time axis also alters the sampling frequency. (2) Recorder function The sampling frequency is fixed. Because changing the sampling frequency does not alter the time axis, measurement at a fast sampling speed is possible even with a slow time axis.
  • Page 38 6. About the screen display and DIV The 8855 is equipped with an SVGA (800 x 600) LCD. The waveform area uses 750 dots horizontally and 500 dots vertically. As there are 30 DIV horizontally and 20 DIV vertically, one grid (1 DIV) on the screen measures 25 dots horizontally and 25 dots vertically.
