• On the RTC
®
5, only
one
pixel mode is available (equivalent to the RTC
®
4’s
PixelMode
= 1) .
• The RTC
®
5 allows selection of the output channel (
Channel
) for analog signals (in pixel
output mode, the RTC
®
4 can only output analog voltage levels at its ANALOG OUT2
port).
• For the RTC
®
5, the pixel output period is specified as the
half
output period
HalfPeriod
(in contrast, for the RTC
®
4 it is the
full
output period
PixelPeriod
).
• For the RTC
®
5, the command
set_pixel_line
requires only one list entry, as with other
normal list commands (whereas the RTC
®
4 requires two list entries).
• In RTC
®
4 compatibility mode,
HalfPeriod
must be specified in units of 1/8
µ
s. The para-
meter values will then be internally converted to 1/64
µ
s units (i.e. multiplied by 8). The
permissible range of values is correspondingly smaller (the smallest permissible value is
then 13). In RTC
®
4 compatibility mode, the RTC
®
5 also multiplies the specified coordi-
nate values
dX,dY
by 16 (the permissible range of values is correspondingly reduced).

Command
set_pixel_line_3d
Function
activates the pixel output mode and defines various pixel output parameters.
Call
set_pixel_line_3d( Channel, HalfPeriod, dX, dY, dZ )
Parameters
Channel
(number of the analog output port).
HalfPeriod
(
half
pixel output period).
dX, dY
:
Distance in the X and Y directions between adjacent pixels in
bits
(64-bit IEEE floating point values)
dZ
Distance in the Z direction between adjacent pixels in
bits
(64-bit IEEE floating point values)
As with all Z-coordinates,
dZ
too is scaled 16x smaller than
dX
and
dY
.
Comments
• Unlike
,
set_pixel_line_3d
lets you define the pixel spacing (between two
adjacent image points on a line) via a
3D
vector.
set_pixel_line_3d
will additionally require two list-memory loca-
tions if parameter
dZ
is non-zero. The initial component executes as a short list
command before the primary component (a normal list command). Any still-pending
delayed short list command will get executed first.
• In other respects,
set_pixel_line_3d
behaves similarly to
(see the
comments there).
