The RadioShack ProbeScope is a microprocessor-controlled oscilloscope and
digital voltmeter housed in a small probe with a backlit mini Liquid
Crystal Display (LCD).  All oscilloscope parameters are menu-driven and
selected by pressing one of two push buttons.  You can quickly and single-
handedly set all parameters while looking at the point of measurement, the
probe's controls, and the display.  This eliminates the need for any head
movement, making the ProbeScope the easiest-to-use measurement tool
available.

The ProbeScope includes these features:

  Ten Selectable Sampling Rates - lets you display signals in a wide
                                  variety of waveforms, from a small
                                  fraction of a waveform to multiple
                                  waveforms of the measured signal.

       Multiple Trigger Sources - lets you select whether the oscilloscope
                                  starts a measurement using an internal or
                                  an external trigger.

  Six Selectable Trigger Levels - lets you select both rising and falling
                                  signal events at different levels.

Selectable Input Voltage Ranges - lets you select the range of the measured
                                  signal for the most accurate readings.

      Selectable Input Coupling - lets you select whether the signal to be
                                  measured is DC or AC coupled to the
                                  scope, and provides a zero reference for
                                  zero adjustment.

             Signal Ground Line - lets you easily reference the incoming
                                  signal.

                   Trigger Jack - lets you connect an external trigger
                                  source.

   Multiple Input Power Sources - lets you connect 9 VDC - 13 VDC external
                                  power from a battery using the supplied
                                  power cable with alligator clips, or an
                                  optional AC adapter.

   Liquid Crystal Display (LCD) - displays the recorded signal.

             Software Interface - lets you use your computer to display and
                                  record measurements.
