When factors are on, the oscilloscope will also print extra information regarding the
waveforms underneath the screen plot. Normally factors is left off. The resolution should be set
low to function properly with the printers available in the labs.
A variety of automatic voltage and time measurements are available through the Voltage
and Time measurement menu buttons. Pressing the Voltage menu button brings up the following
options:
 Source for the measurement: channel 1 or 2
 V
p-p
, V
avg
, V
rms
, V
max
, V
min
, V
top
, and V
base
; the first three are
available on the first ―page‖ of the menu while the last four are
available by hitting the ―Next Menu‖ softkey
 Clear Measurement
 Show Measurement off/on
The Clear Measurement option will erase any selected measurements. The Show
Measurement option displays cursors on the screen when on. For example, if the measurement
V
p-p
is selected, two horizontal cursors that are ―locked‖ to the topmost and bottommost parts of
the selected waveform will be displayed on the screen. The location of these cursors varies with
the selected measurement.
Pressing the Time menu button brings up the following options:
 Source for the measurement: channel 1 or 2
 Frequency, Period, Duty Cycle, + Width, - Width, Risetime and Falltime; as with
the voltage measurements, the first 3 are found on the first page of the menu, with
the rest on the following page
 Clear Measurement
 Show Measurement off/on
If you ever need to perform voltage or time measurements other than
the automatic ones listed above, there are a set of voltage and time cursors
available when the Cursors menu button is pressed. It will bring up the
following items:
 Source for the cursors: channel 1 or 2
 Active cursor: V1, V2, t1, t2
 Clear Cursors
When a particular cursor is selected by an active cursor softkey, it may be moved by
using the unmarked knob underneath the Cursors menu button. Cursors should be placed on the
scope trace at the centre of the trace thickness. Its present value (location) in volts or seconds is
displayed underneath the waveform display area of the screen as well as the present value of the
