Fundamentals
Like any oscilloscope, this instrument draws a graph of voltage as a function of
time.
The VERTICAL controls, marked off by a heavy gray line, define the voltage axis
of the display. SEC/DIV, XI0 MAG, and horizontal POSITION control the time axis of
the display. The TRIGGER controls, marked off by a green box, define the signals
required to initiate sweeps across the time axis. The controls under the CRT affect the
display but not the waveform.
Parametric Measurements
The Parametric Measurement function provided in the instrument gives quick
access to the parameters of your input signal.
To obtain a parametric measurement, simply press the MEASURE button and
select the desired function from the displayed menu. The function is selected by
pressing the button in the VERTICAL MODE area that occupies the same relative
position as the desired menu selection. The measurement function will
automatically scale the input signal before making the measurement.
Parametric measurements require repetitive signals for reliable results.
Measurements on non-repetitive signals will produce unpredictable results.
Repetitive signals that have periodic bursts of signal transitions will also produce
unpredictable results.
Parametric measurements can only be performed on signals in CH 1 or CH 2.
An error message will be displayed if CH 3, CH 4, or ADD are selected for
parametric measurements.
