Front-Panel Controls
NOTE. Locations for the following controls are shown in Figure 2–1.
Power
1. POWER. The Power push-button switch turns the instrument on
or to standby status, and displays a colored spot inside the switch
when power is on.
CRT Controls
The five CRT controls (Focus, Scale, Intens, VPOS, and HPOS) are
used to adjust both CRTs. Assignment of these controls from one
CRT to the other is controlled by two illuminated switches, one
under the left CRT and one under the right CRT.
When <TIMEOUT> <ON> is selected (Configure menu, described
in Section 3), vectorscope assignment of CRT controls will revert to
waveform assignment after 30 seconds of no knob activity.
The settings of the five CRT controls are saved and restored when
toggling between waveform and vector assignments.
2. Left switch. This switch assigns the Focus, Scale, Intensity, and
Position controls to operate with the left (vectorscope) CRT.
3. Right switch. This switch assigns the Focus, Scale, Intensity, and
Position controls to operate with the right (waveform monitor)
CRT.
4. SCALE. The Scale control adjusts the level of graticule
illumination. A beep indicates the limits of the control range.
5. FOCUS. The Focus control adjusts the beam for optimum
definition. A beep indicates the limits of the control range.
6. INTENS. The Intensity control adjusts display brightness. A beep
indicates the limits of the control range.
