Controls, Connectors, and Indicators
Activates the Parametric Measurements menu.
Selections from the menu are made using the
VERTICAL MODE buttons. Repeated activation of the
MEASURE button will cycle through a series of
explanatory text in the lower CRT readout.
Set vertical position of the Channel 1 and Channel 2
signal displays. Clockwise rotation of a control moves
the associated trace upward. When the X-Y display
feature is in use, Channel 1 POSITION control moves
the display horizontally; clockwise moves it to the right.
The Channel 2, Channel 3, and Channel 4 vertical
POSITION controls move the associated X-Y display
vertically.
Select the indicated channel(s) for display. Any
combination of the five possible signal selections can be
displayed by pressing the appropriate buttons. The
Channel 1 signal will be displayed if none of the displays
are selected. Each button has an associated indicator to
show when the respective display or characteristic is
active. Pressing a button toggles the display or
characteristic on or off. When pressed after pressing
SAVE or RECALL, these buttons select setup memories
(1) through (8).
These buttons also select the various entries in the
displayed menu when the buttons are pressed after
pressing the MEASURE button.
When multiple channels are selected, they are displayed
sequentially in order of priority. The established priority
order is: CH 1, CH 2, ADD, CH 3, then CH 4.
The algebraic sum of Channel 1 and Channel 2 is
displayed when the Add display is selected. When
both Add and Invert displays are selected, the
waveform displayed is the difference between the
Channel 1 and Channel 2 signals. The INVERT
button also inverts the polarity of the signal output at
the CH 2 SIG OUT connector on the rear panel. At
the same time, the Channel 2 trigger-signal polarity is
inverted so that if CH 2 is selected as the TRIGGER
SOURCE, the displayed slope will agree with the
TRIGGER SLOPE setting.
