Model 801GC, 801GF & 801GX¥Rev. A
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.
