Sigma LBA-712, LBA-710, LBA-300, LBA-708, LBA-500PC, LBA-700 manual 4.16 RDD? read raw data, LBA-714PC

Use the :FST? command to determine the specific fixed point format of pixels in a frame. The PixelBits parameter specifies the number of integer bits. The PixelBitsFraction parameter specifies the number of fraction bits.

A.5.4.16 RDD? - read raw data

Returns the binary frame data. :RDD? <configuration>

Key	Type	Value Description
FrameNumber	I	frame number
		-1 = gain frame
		0 = reference frame
		1 to n. ‘n’ is the size of the frame buffer.
		default = current frame

Returns:

RDD FrameNumber=f;Width=w;Height=h;#dn..n(DAW)(DAW)…(DAW)

Where:

f	=	frame number
w	=	number of columns
h	=	number of rows

#= pound symbol

d	=	number of digits to follow in n..n
n..n	=	number of data words
(DAW)	=	data word is two 8-bit data bytes, low byte followed by high byte

Each data word is a two’s complement fixed point value in one of the following formats:
