AVCO <type>

Limits: <type>

0 = RGB (Normal)

1 = RBG R>R B>G G>B

2 = GRB G>R R>G B>B

3 = GBR G>R B>G R>B

4 = BRG B>R R>G G>B

5 = BGR B>R G>G R>B (Apple 15" on 13W3)

Description: Changes which analog video channel is used for a particular color

AVCS <type>

Limits: <type>

0 = No subcarrier

1 = NTSC_M

2 = NTSC_443

3 = PAL_BD

4 = PAL_N

Description: Analog video color sub-carrier selection (Not used on 801GC or 801GC-ISA)

AVPG <mode>

Limits: <mode>

0 = OFF

1 = ON

Description: The AVPG command enables and disables the analog video setup pedestal when an analog

video signal is being generated (see AVST command). The AVPG? query returns the current

setting of AVPG.

AVPS <level>

Limits: <level>

min =

max =

Description: Analog video pedestal swing

AVSC <red factor>, <green factor>, <blue factor>

AVSC <common factor>

Limits: <factor> (floating point accepted)

min = 0.000

max = 1.000

Description: The AVSC command sets the analog video calibration (or scaling) factor that is used to adjust

the level set by AVSS. Issuing the command with a single factor sets all three analog video

channels to the same value. Issuing the command with three factors sets each of the analog

video channels to each of the given values. The actual peak-to-peak swing of the analog

video signals at the output connectors is equal to the product of: AVSS multiplied by AVSC.

The AVSC? query returns the current setting of AVSC for each channel. The default factory

setting is 1.000 for this parameter.

❖ The AVSC parameter is a system level parameter that will affect the analog video swing

of all Formats that are recalled. The AVSC value will be retained when the generator is

powered down and back up again. Query the current setting of AVSC if you are

experiencing low or missing analog video levels.
