Waveform Setup Menu
The Waveform Setup menu is described below.
Digital Waveform Graticule
The Digital Waveform Graticule menu is used to select the unit of measurement for the
Digital Waveform Graticule. The selections are Volts or Percent. The default selection
for the Digital Waveform Graticule menu is VOLTS.
NTSC Pedestal (or 7.5 IRE Setup)
When in 525/60 Composite format, set the NTSC PEDESTAL to OFF if using a 0 IRE
pedestal signal. When set to OFF, the Vector graticules change to the proper levels in
order to display an NTSC signal without 7.5 IRE setup. The NTSC PEDESTAL default
position is ON (7.5 IRE).
PAL Waveform Scale
The PAL Waveform scale menu is used to select the unit of measurement for the PAL
Waveform. The selections are Volts or Units. The default selection for the PAL
Waveform menu is UNITS.
DC Restore (Analog Option Required)
DC Restore is used to have the voltage supplied to the analog signal in order to
maintain a DC level on the waveform. The blanking level is offset and shifts due to the
presence or absence of burst: 1 IRE unit or less. The DC Restore selections are Off,
Fast, and Slow.
• Off = DC offset appears.
