:WAVeform Commands
Digital Channel Data (MSO models only)
The waveform record for digital channels is similar to that of analog
channels. The main difference is that the data points represent either
DIGital0,..,7 (POD1), DIGital8,..,15 (POD2), or any grouping of digital
channels (BUS1 or BUS2).
For digital channels, :WAVeform:UNSigned (see
ON.
Digital Channel POD Data Format
Data for digital channels is only available in groups of 8 bits (Pod1 = D0 -
D7, Pod2 = D8 - D15). The bytes are organized as:
:WAVeform:SOURce
POD1
POD2
If the :WAVeform:FORMat is WORD (see
data byte will be 0. The setting of :WAVeform:BYTeorder (see
controls which byte is 0.
If a digital channel is not displayed, its bit value in the pod data byte is
not defined.
Digital Channel BUS Data Format
Digital channel BUS definitions can include any or all of the digital
channels. Therefore, data is always returned as 16- bit values. :BUS
