Front Panel Organization; Controls, Connectors, And Indicators - Tektronix 2205 Operator's Manual

FRONT PANEL ORGANIZATION

The 2205 front panel is organized to make it easy for you to
display signals and make measurements.
dout illustration, Figure 2 -1 , or to the oscilloscope itself, notice
that the front panel is partitioned into four major control sections
- Display, VERTICAL, HORIZONTAL, and TRIGGER.
Just to the right of the cathode-ray tube (crt) screen are the
Display controls. Display controls affect the display, but not the
waveform. These controls adjust brightness and focus of the
trace, align the trace with the graticule, and help you quickly find
off-screen signals.
Like any oscilloscope, the 2205 draws a graph of voltage as a
function of time. The VERTICAL section, enclosed within shaded
gray lines, contains the controls that define the voltage (or verti­
cal) axis of the display.
BNC input connectors, through which you apply the signals that
you want to view.
The HORIZONTAL controls are to the right of the VERTICAL sec­
tion. Horizontal controls set and move the time (or horizontal)
axis for the displayed traces.
On the extreme right of the front panel, enclosed within shaded
green lines, is the TRIGGER section. Trigger controls define the
signals and the conditions needed to initiate (or trigger) every
sweep across the time axis. An indicator light (TRIG'D) comes
on when the sweep is triggered. A BNC input connector at the
bottom of the TRIGGER section lets you apply either an external
trigger signal or an external Z-axis (display intensity) control sig­
nal.
CONTROLS, CONNECTORS, AND
INDICATORS
Table 2-1 lists all the controls, connectors, and indicators on
your 2205 Oscilloscope. Following Table 2 -1 , a short procedure
describes how to get a display.
offers suggestions and tips for using the controls to obtain the
most effective displays and to make the most accurate meas­
urements.
