    ----------------------------------------------
    The 7D20 Programmable Digitizer Plug-In is a GPIB programmable plug-in that is compatible with all 7000 Series mainframes (including the USM 281C) except the 7104. When combined with a 7000 Series mainframe, this plug-in creates a fully programmable, digitizing oscilloscope. The unit can accurately measure the amplitude of a 50 ns wide transient event. 70MHz Bandwidth for Repetitive Signals 10MHz Single-Shot Bandwidth Dual Channel Simultaneous Acquisition.
    =================================
    The Tektronix 7D20 is a GPIB-Programmable Digitizer plug-in for Tektronix 7000-series oscilloscope mainframes. It performs simultaneous sampling on both of its' input channels, with 70 MHz bandwidth for repetitive signals, and 10 MHz BW for single-shot events. Other features include:
  • Digital storage of six waveforms
  • Storage and recall of six setups
  • Two cursors for waveform measurement functions
  • Waveform averaging
  • Complete programmability via GPIB
