X10 MAG
Button
Positions the B trace downward from the A trace in Alt
horizontal display mode. In the B horizontal display
mode, with At or 1/At, TRACE SEP positions the trace
associated with the A control downward. Fully clockwise
rotation eliminates separation between the traces.
Horizontally positions the sweep displays.
Horizontally magnifies the portion of the sweep display
positioned at the center vertical graticule line by a factor
of 10. When in Alt or B horizontal display mode, only the
B-Sweep is affected.
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 DL Y matching function. With the available TV enhancement, A also
serves as a line number selector and "FLO LINE #" nomenclature is added. With
the available CIT, A REF and A serve as menu selectors, with "MENU SELECT"
nomenclature added, and also as delaying-event-count controls. With the available
WR, they serve as word definition controls.

AV Button
5-14
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 DL Y 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 VOL TS/DIV VAR control of the
channel determining the scale factor is out of the
detent position.
2. When the Add vertical display mode is selected
alone and the Channel 1 and Channel 2
VOL TS/DIV settings are not the same.
Pressing the A V button when the function is active
cancels
tN.
Pulling SEC/DIV out also cancels the
Delta Volts function.
