Microprocessor control and digital synthesis give the 408 and 408NPS extreme flexibility in test ** programming of both video and RF outputs. Signals available simultaneously include composite video,Y/C,Y/RY/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 while the 408NPS extends all operating features into PAL and SECAM as well.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,** 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.
