ED701 - miniScope

Mini Scope

The ED701 is a small utility module that provides the user with the ability to quickly visualise signals in their system.

The 'Analyser' area to the left displays the FREQUENCY and PEAK-PEAK values of the input signal along with the THRESHOLD, TIMEBASE and FULL-SCALE settings of the miniScope controls.

When in [DC MODE], pressing the [OPTION] button will toggle the 'Analyser' area in to an alternate display where it will show the MEAN, MAXIMUM and MINIMUM voltage values of the input signal.

Pressing and holding the [MENU] selects the 'PARAMETER MENU] where the user can specify:-

TRIGGER MODE: OFF (free-running), RISE - triggers on rising edge, or FALL - triggers on falling edge
TRIGGER VALUE:
TIMEBASE: Set the TIMEBASE - 28kHz (35uS/Sample), 5kHz (200uS/Sample), 2.5kHz (400uS/Sample), 625Hz (1600uS/Sample) or 156Hz (6400uS/Sample)
AUTO: Enable or disable the AUTO trigger mode
LINES/DOTS: The input signal can be displayed as s eries of DOTS or LINES
INVERTED/NORMAL: In some environments switching the display to White-On-Black can provide a more easily readable display. NORMAL mode is Black-On-White

Each setting is highlighted one at a time starting from the TRIGGER MODE. Pressing the [OPTION] key toggles through the available options while pressing the [MENU] key steps to the next setting downthe screen. After the last setting , the user is returnd to the [SCOPE MODE].

The ED701 would normally be used in [AC MODE] as its main function is to show wave shapes. Switching to [DC MODE] allows rough measurements of DC levels to be viewed.
