Controls, Connectors, and Indicators
Delay and Delta Controls
The AV, At and TRACK/INDEP buttons, with the A REF OR DLY POS and A
rotary controls, are used to make voltage, time, frequency, ratio, and phase
measurements. These controls also affect the SAVE and RECALL functions and
the CH 2 DLY matching function. With the available TV enhancement, A also
serves as a line number selector and "FLD LINE #" nomenclature is added. With
the available CTT, A REF and A serve as menu selectors and as delaying-event-
count controls. With the available WR, they serve as word definition controls.
33) AV Button Activates the Delta Volts measurement function and
cancels the At or 1/At measurement function. When the
AV function is active, two horizontal cursors are
superimposed on the display. The CRT readout shows
the equivalent voltage between the two cursors. Cursors
are positioned by the A REF OR DLY POS control and
the A control. With multiple vertical displays, the
deflection factor of the first selected channel in the
display sequence determines the cursor scale factor.
The cursor readout is displayed as a percent RATIO
under either of the following conditions:
1. When the VOLTS/DIV VAR control of the
channel determining the scale factor is out of the
detent position:
When the Add vertical display mode is selected
alone and the Channel 1 and Channel 2
VOLTS/DIV settings are not the same.
Pressing the AV button when the function is active
cancels AV. Pulling SEC/DIV out also cancels the
Delta Volts function.
