Figure 2-4. Vertical controls, connectors, and indicators.
@VOLTSIDIV Variable Controls-When rotated
counterclockwise out of their calibrated detent
positions, these controls provide continuously
variable, uncalibrated deflection factors between
the calibrated settings of the VOLTSIDIV switches.
@
POSITION Controls- Used to vertically position
the display on the CI?. When the SECIDIV switch is
set to X-Y, the Channel 2 POSITION control moves
the display vertically (Y-axis), and the Horizontal
POSITION control moves the display horizontally
(X-axis).
@
A16 SWP SEP-Vertically positions the B Sweep
trace with respect to the A Sweep when ALT Hori-
zontal MODE is selected.
@Input Coupling AC-GND-DC Switches-Three-
position switches that select the method of coupling
the input signals to the instrument deflection system.
AC
-
Input signal is capacitively coupled to the
vertical amplifier. The dc component of the input
signal is blocked. Low-frequency limit (-3 dB
point) is about 10 Hz.
