| Microprocessor control and digital synthesis give the
408 extreme flexibility in test signal programming of both video and RF outputs.
Signals available simultaneously include composite video, Y/C, Y/R-Y/B-Y, GBR,
full sync generator outputs, audio test tones (400 Hz and 1 kHz) and modulated
output from 30 to 900 MHz. Multiple test patterns include wide and narrow video
sweeps and multiburst with last burst variable to 15 MHz. Signal modifiers
include polarity inversion, superimposed circle and moving marker as well as
on/off and level control of burst, sync, setup, luminance, chroma, R, B and G.
Genlock and remote control are standard. GPIB is available as an option. The 408
operates in the NTSC system. Applicable video and audio modulation is selected
by system designation. The FUNCTION DATA block provides easy access to all
programming functions. Here, up to 100 test setups can be stored, each one
holding front panel settings (pattern selected, genlock on/off, signal
modifiers, etc.), tailored or standard video parameters. RF channel selected or
tailored to any carrier frequency between 30 and 900 MHz. Program control over
video parameters allow component values for Betacam or MII to be set up. The LCD
panel shows partial programming menus, but the full menus may be superimposed on
the selected pattern on a monitor screen. |
