WFM 601A, WFM 601E, & WFM 601M Service Manual
Displays a status screen providing EDH error statistics, including ANC data
errors and line/field length errors. In addition, the WFM 601E and WFM 601M
waveform monitors provide screens that report format errors, signal strength, and
cable length information. This area includes two indicators:
EDH DET. Lights up when the serial digital signal has the SMPTE RP165
specified Error Detection and Handling (EDH) signal.
ALARM. Lights up when a serial video data or format error occurs, or when the
serial signal is lost.
Selects either internal serial digital or external composite video input for the
instrument synchronization reference.
Provides access to configuration and measurement functions that affect the
DISPLAY mode. Press a MENU button to display that menu and enable the
associated functions. Press the button again to exit the menu and disable the
function.
Puts the waveform monitor into the standby or operational state.
Turns off the MENU function readouts without affecting the menu settings. Also,
provides access to alternative displays in some display modes.
Using the Menus
The waveform monitors have a set of front-panel selectable MENU buttons that
call up CRT readout menus. These menus operate in conjunction with the five
bezel buttons along the side of the CRT and the three knobs directly beneath it.
See Figure 2–7.
Enabled menu selections are surrounded by a rectangle to indicate that they are
active.
Pressing the CLEAR MENU button turns off the menu readout while leaving the
functions associated with the current Display mode.
Pressing a MENU button when its menu is displayed turns off both the menu
readout and, in most cases, disables the function. By selecting Line Select,
Cursor, Filter, or Gain, the last settings are returned. For example, if X5 was
active when you last used the Gain menu, returning to the Gain menu restores X5
gain.
