displayed) may be set anywhere from off (minimum persistence) to infinite. Several times are
selectable in-between these two extremes.
The display format is normally left set to YT; this is the normal volts vs. time display of
the scope. When you wish to display one waveform vs. another, set the format to XY. When in
the XY mode, channel 1 is the X (horizontal) waveform, and channel 2 is the Y (vertical)
waveform. While in this display mode, the channel 1 volts/div and position knobs control the
horizontal scale and position, while the channel 2 volts/div and position knobs control the
vertical scale and position.
The contrast softkeys change the display contrast of the scope.
Measurements and Cursors
A number of automated measurements are possible when the measure menu button is
pressed:
Source/Type
Any four of the following
measurements: frequency, period, mean (average), pk-pk, cyc rms (true rms
computed over one cycle), rise time, fall time, positive width, negative width, or
none
The four measurement readout windows adjacent to the bottom four softkeys list the
channel being measured (CH1 / CH2), the specific measurement (as listed above), and the
measured quantity. The top softkey selects between the source channel selection mode or the
measurement type selection mode. When Source is selected, the source channels in the
measurement windows become highlighted. Pressing one of the bottom four softkeys will toggle
the selected source channel, but will not change the measurement type. When Type is selected,
the measurement type will be changed by the bottom four softkeys, but not the source channel.
A set of voltage or time cursors is available by pressing the Cursor menu button. The
following items then appear:
Cursor type: off/voltage/time
Source CH1 / CH2 / MATH / Ref A
/ Ref B
The only deficiency that this scope has is
its cursors. Unfortunately, only the voltage or time
cursors can be displayed, but not both at once.
This may be an issue, depending on the lab you are performing. The menu choices available
