 Indicators 
Introduction 
The following descriptions are intended to familiarize the operator with the 
location and function of the instrument's controls, connectors, and indicators. 
All continuously variable controls, except FOCUS, TRACE ROTATION, 
ASTIGMATISM, and SCALE ILLUMINATION have fine resolution for a portion of 
their rotation after each reversal. Continued rotation in the same direction gives 
progressively coarser resolution.

(2J BEAM FIND Limits the CRT deflection both vertically and horizontally 
Button to within the graticule. Display intensity is not affected 
by the BEAM FIND button. 
FOCUS Adjusts the CRT writing beam for optimum display 
Control definition. 
TRACE Aligns the no-signal trace with the horizontal graticule 
ROTATION lines. Relocating the instrument to a different magnetic 
Control ambient may result in slight misalignment of the trace 
and graticule, indicating a need to readjust the TRACE 
ROTATION control, using a screwdriver. 
READOUT This control adjusts the intensity of the CRT readout 
INTENSITY display and will either enable or disable the display of 
Control scale factors. Digital measurements, Save/Recall 
readouts, the "50 fl OVERLOAD" message, the 
available Counter/Timer/Trigger
 (CTT)
 menu,
 and the 
available Television/Video
 (TV)
 function indicators are 
always enabled.
