Procedure
1. Initialize the Front-Panel Controls
The TektronixWFM 601i Serial Component Monitor is shipped with an internal
preset which sets the front-panel controls to a factory-defined setting. To reset
the front-panel controls to the factory presets, enter the MENU by pressing the
PRESET button. Select the FACTORY setting by turning the front-panel bezel
knob under the list of presets until FACTORY is highlighted. Press the bezel
button adjacent to RECALL. The PRESET MENU is automatically exited, and
the front-panel control settings are set to the factory preset. This preset
automatically selects the line rate (625 or 525). Note that upper left hand corner
of the CRT displays the scan rate with a readout preceded by an
A (scan rate
automatically selected.) Check that the instrument is now in the Waveform
display mode with the luminance portion of the Color Bar signal displayed at a
line sweep of 10
m
s/Div.
2. Display Control
Adjust the VERT and HORIZ POS knobs to center the signal display. The CRT
menu allows the operator to adjust the instrument CRT display. Enter the menu
by pressing the
CRT
button. The knobs under the CRT now control the focus,
scale illumination, and display intensity of the signal. Adjust the controls to the
desired viewing levels. See Figure 1-12.
