SDI7 Dual Channel SD/HD/3G SDI Video Generator module
To select a zone plate
signal o n the SDI7 module
Perform the fol
lowing steps to select a zone plate signal for output:
1. Press the SWEEP test signal button to enter the zone plate signal menu. Once
you enter the z
one plate signal menu, the SDI7 generator module will start to
output the displayed zone plate signal. The dot in front of the signal name, on
the second line of the display, indicates the selected default signal.
2. Use the left (◄)orright(►) arrow button to select a zone plate signal from
the provided six standard zone plate s ignals (Circle, Diagonal, Horizontal
Sine, Horizontal Sweep, Vertical Sine, or Vertical Sweep), or from the two
user-defined signals (Custom-1 Zoneplate or Custom-2 Zoneplate).
The zone plate signal whose name is displayed will continue to be output until
a different signal is selec t ed, even if you press the BACK button.
If you select a different signal, such as a color bar signal, and then press the
SWEEP button again, the last displayed zone plate s ignal will be shown as
the default and will again be the output signal.
To modi
fy a zone plate
signal o n the SDI7 module
There are times when a specific test case requires a modified zone plate signal.
By making and saving changes to the zone plate parameters you can create a new
signalthatisbasedontheselectedsignal, and then save that new signal. Changes
you ma
ke affect only the new signal; the standard zone plate signal used as a
basis for the new signal is not changed.
Befo
re making changes, make sure you are familiar with both the zone plate
pattern control parameters (below) and zone plate pattern dependent parameters.
(See page 3-275, SDI7 module zone plate dependent parameters.)
Perform the following steps to cha nge a zone plate signal's parameters:
1. Pr
ess the SWEEP button to enter the zone plate s ignal menu.
2. Use the left (◄)orright(►) arrow button to select a zone plate signal
f
rom the provided six standard zone plate signals (Circle, Diagonal, H Sine,
H S weep, V Sine, and V Sweep), or two user-defined signals (Custom–1
Zoneplate or Custom–2 Zoneplate).
