Quantum Data 801GC, 801GF, 801GX Vertical active must be even when in inter- laced scan mode

2321 Vertical active must be even when in inter- laced scan mode

The generator does not support vertical active periods (in lines) that cannot be evenly divided by two (2) when interlaced operation is selected.

■Make the vertical active period (in lines) evenly divisible by 2.

■Change to progressive (non-interlaced) scan mode.

2330 Vertical blanking too small

There must be at least 3 lines of vertical blanking with interlaced operation.

■Increase the vertical period.

■Decrease vertical active.

■Switch to non-interlaced operation.

2350 Vertical pulse too small

The generator does not support a vertical sync pulse width value of less than one scan line in duration. The firmware makes the pulse a half-line shorter than the entered value when European type sync is selected.

■Increase the vertical sync pulse width.

2370 Vertical pulse too large

The generator does not support a vertical sync pulse width greater than the number of blanked scan lines per frame with non-interlaced operation.

■Decrease the value of vertical sync pulse width.

■Increase the value of vertical period (in lines).

■Decrease vertical active.

2390 Vertical pulse too large

The generator does not support a vertical sync pulse width greater than the least number of blanked scan lines ((Vper

-Vact - 1) ⎟ 2 ) between fields with interlaced operation.

■Decrease the value of vertical sync pulse width.

■Increase the value of vertical period (in lines).

■Decrease vertical active.
