Display Controls; Vertical Controls; Input Coupling - Tektronix 2205 Operator's Manual

Operation
Congratulations! You now know how to use the 2205 front-panel
controls to display signals and move them about on the screen.
The remainder of this section gives you more information about
the controls and offers suggestions for their use. Section 3 ex­
plains how to make specific types of measurements and how to
use the other controls not covered in the preceding exercise.

DISPLAY CONTROLS

Set the INTENSITY control for comfortable viewing, but not
brighter than you need.
low-repetition-rate signals, narrow pulses in long time intervals,
or occasional variations in fast signals.

VERTICAL CONTROLS

When making voltage measurements, rotate the VOLTS/DIV CAL
control fully clockwise (in detent). Best accuracy is achieved by
setting the VOLTS/DIV control for the largest display possible.
When a cable or a signal adapter is used to connect a signal, the
number in the I X front-panel area indicates sensitivity. When
using a 10X probe, the number in the 10X PROBE front-panel
area indicates sensitivity. For example, the setting of 1 V/div
with a cable or signal adapter would be 10 V/div with a 10X
probe. And, although the knob skirt is not marked, 5 V/div at IX
would be 50 V/div if a 10X probe were used.

Input Coupling

For most applications, use DC input coupling.
compatible with the standard accessory signal adapters and it
displays logic levels and DC levels of static signals.
Use GND input coupling to show where the zero-volt level will be
located when you shift to DC or AC coupling.
Use AC coupling for the special cases where you need to see
small signals on large DC voltage levels.
