Signal Type Menu 

 

A Signal Type menu(s) is displayed by pressing the 
Signal Type pushbutton. This menu lists the different 
output video signal types that may be produced by 
the generator. Pressing the + or – pushbuttons show 
additional signal type selections. An asterisk 
indicates the selected or active signal type. Pressing 
the pushbutton beside the signal types listed in the 
display selects that signal type for output by the 
generator.  

 

HDTV/SDTV – YPbPr:

 Analog luminance 

(Y) and color difference signals (Pb,Pr) per 
EIA standards commonly referred to as 
component video. 

HDTV/SDTV 

– RGB: Analog red, green and 

blue video signals per EIA standards. 

VESA/Mac – RGB

: Analog red, green and 

blue video signals per VESA and Apple/Mac 
standards. 

NTSC/PAL

: Analog composite color base-

band video signal via BNC connector or 
separate analog luminance (Y) and 
chrominance (C) video signal via S-video 
connector or RGB component video via 
analog pins of DVI connector per NTSC or 
PAL standards. NTSC RF video signals via 
RF connector on channel 2, 3, 4, or 6. 

HDTV/SDTV – RF – 8VSB

: TV Digital 

video with RF carrier modulated with 8 level 
vestigial side-band modulation, per ATSC 
standards, on channels 2-4, 7-10, and 30-32. 

HDTV/SDTV – DVI:

 Single link digital 

video interface of red, green, blue 
HDTV/SDTV video signals via differential 
data and clock lines with a standard DVI 
connector. 

VESA/Mac – DVI

: Single link digital video 

interface of red, green, blue video signals per 
VESA and Apple/Mac standards via 
differential data and clock lines with a 
standard DVI connector. 

SDI/HDSDI –

 Serial digital video interface of 

multiplexed Y, Cr, Cb video signals.  

User

: User defined video formats.

 

 

Format Menu 

 

A Format menu(s) is displayed by pressing 
the FORMAT pushbutton. This menu is 
also automatically displayed when a new 
Signal Type is selected in the Signal Type 
menu. This prompts you to select the 
desired format to fully define the 
generator’s output signal. 

 

The Format menu(s) lists the different 
signal formats that can be produced for the 
selected Signal Type. Pressing the + or – 
pushbuttons shows additional format 
selections. An asterisk indicates the selected 
or active format. Pressing the pushbutton 
beside the format listed in the display, 
selects the format for output by the 
generator.
