V E R T I C A L A X I S C O N T R O L
( D V O L T S / D I V
V e r t i c a l a t t e n u a t o r f o r c h a n n e l 1 ; p r o v i d e s s t e p
a d j u s t m e n t of vertical sensitivity. W h e n the V A R I A B L E
control is t u r n e d t o the C A L position, the vertical sensitivity
is calibrated in 10 steps f r o m 5 V / d i v to 5 m V / d i v . For X-Y
operation this control provides step a d j u s t m e n t of vertical
sensitivity.
(2) V A R I A B L E
Fine a d j u s t m e n t control CH1 vertical attenuation. This
control provides c o n t i n u o u s a d j u s t m e n t b e t w e e n the
V O L T S / D I V ranges. W h e n set to its e x t r e m e clockwise
(CAL) position, t h e attenuator is calibrated. For X-Y
operation, this control serves as the Y-axis a t t e n u a t i o n fine
adjustment. A s this fine adjuster uses a variable resistor
w i t h a center t a p , the a m p l i t u d e s o m e t i m e s does not
change during rotation.
(3) $ P O S I T I O N / P U L L X 5 G A I N
This is a p o t e n t i o m e t e r control w i t h an a d d e d s w i t c h
f u n c t i o n . It serves as t h e C H 1 vertical position control for
normal operation a n d X-Y operation as w e l l . W h e n pulled
out, the V O L T S / D I V setting is multiplied by 5 a n d for X-Y
operation the Y-axis sensitivity is m u l t i p l i e d accordingly.
In X 5 G A I N m o d e , the vertical gain is increased and the
trace b e c o m e s thickness.
(4) U N C A L
This LED lights t o indicate that CH1 is not calibrated, i.e.,
t h a t the V A R I A B L E control is not in the C A L position.
(5) P U L L X 5 G A I N
This LED lights to indicate that the CH1 $ POSITION
control is in the pulled out position, i.e. that the CH1
sensitivity is five t i m e s the V O L T S / D I V setting.
(6) A C - G N D - D C
This s w i t c h is t h e C H 1 vertical axis c o u p l i n g m o d e
selector, for X-Y operation, the Y-axis coupling m o d e
control.
A C : A C input coupling, w i t h blocking of any DC signal
c o m p o n e n t .
G N D : Vertical amplifier is disconnected f r o m t h e input
signal and c o n n e c t e d to ground. This m o d e is
useful in d e t e r m i n i n g the actual g r o u n d potential.
DC: DC coupling, w i t h both the DC and A C c o m p o n e n t s
of the input signal displayed on the CRT.
(7) P U S H 5012
This control selects the C H 1 input resistance b e t w e e n
50i2 and 1 M f i . In the depressed position the input
resistance is 5012.
I — C A U T I I O N :
In the 50Q input m o d e , the m a x i m u m input voltage is
5 V r m s or DC ± 5 V . Care should be taken not to exceed
this level as d a m a g e t o the C S - 2 1 0 0 A could result.
