M 4) UNCAL Indicator—LED illuminates to indicate that
either Channel 1 or Channel 2 VO LTS/D IV VAR
control is out o f calibrated detent (vertical deflection
factor is uncalibrated).
VE R TIC A L MODE Switches—Five push-button
switches that select the mode o f operation fo r the
vertical amplifier system.
CH 1—Selects only the Channel 1 input signal for
display.
A L T —The display alternates between Channel 1
and Channel 2 input signals. The alternation
occurs during retrace at the end o f each sweep.
This mode is useful fo r viewing both vertical
input signals at sweep speeds from 0.2 ms per
division to 0.05 ps per division.
CHOP—The display switches between the Channel
1 and Channel 2 input signals during the sweep.
The switching rate is approximately 500 kHz.
This mode is useful fo r viewing both Channel 1
and Channel 2 inputs at sweep speeds from 0.5 ms
per division to 0.5 s per division.
AD D —Selects the algebraic sum o f the Channel 1
and Channel 2 input signals for display.
CH 2—Selects only the Channel 2 input signal
fo r display.
AU TO —Press in both A LT and CHOP buttons.
The A Sweep circuitry automatically selects the
most useful switching method (A LT or CHOP)
fo r dual displays.
X -Y —Press in both CH 1 and CH 2 buttons. The
X-signal is applied through the Channel 1 input
connector, and the Y-signal is applied through
the Channel 2 input connector.
( j? ) CH 2 INVERT Switch—Inverts Channel 2 display
when button is pressed in. Push button must be
pressed in a second time to release it and regain a
noninverted display.
( l7 ) POSITION Controls—Determine the vertical position
o f the displays on the crt. When X-Y VERTICAL
MODE is selected, the Channel 2 POSITION control
moves the display vertically (Y-axis), and the Hori­
zontal POSITION control moves the display hori­
zontally (X-axis).
