innovators for industry
Ctrl Command get_transform
Function Like get_transform_offset, but without parameter Channel1 , Channel2 , Offset .
Call get_transform( Number, Ptr1, Ptr2, Ptr, Code )
Parameters Number Number of to-be-backward-transformed position values.
As an unsigned 32-bit value.
Allowed value range: [1…2
24
].
The measured values with indices 0 to ( Number –1) are backward transformed.
Ptr1 Like get_transform_offset.
Ptr2 Like get_transform_offset.
Ptr Like get_transform_offset.
Code Like get_transform_offset.
Comments • get_transform( Number, Ptr1, Ptr2, Ptr, Code )
– Transfers the data pairs recorded with set_trigger/set_trigger4/set_trigger8 to the
PC with
• get_waveform(1,Number, Ptr1) and
• get_waveform(2,Number, Ptr2)
Overwrites the data pairwise with transform( Sig1, Sig2, Ptr, Code )
• Comments, page 441 on get_transform_offset apply analogously.
RTC4RTC6 New command.
Even in the RTC4 Compatibility Mode, all coordinate values transferred to the PC are in the
RTC6 20-bit range. The backward transformed coordinate values must, if necessary, be
divided by 16 by users themselves.
RTC5RTC6 Basically unchanged functionality. However:
Allowed value range of Number remains [1…2
23
].
Version info Available as of DLL 600, OUT 600, RBF 600.
Last change DLL 635, OUT 636: Number . Allowed value range extended to [1…2
24
]
(previously: [1…2
23
]).
