Table 3: Channel selection masks
For example, if the bitwise-Boolean expression (captureDataMask & x02000) is non-zero,
then current data for the Aux1 channel is being recorded in the file. If (captureDataMask
& 0x0700) is non-zero or (captureDataMask & 0x8000) is non-zero, then voltages and
markers are being recorded in the file. The section on the sample data will explain this
further.
The file is padded with zeros until offset 272 (144+128), where a Status packet from the
Power Monitor hardware is recorded, as follows:
