Table 7-30 shows an example of an 8-bit ASCii
waveform CURVe transfer. Transmission length depends
on specific data values, record length, acquisition mode
and smoothing, and whether the acquisition was 1 or 2
channels.
REMOTE-LOCAL OPERATING STATES
The following paragraphs describe the two operating
states of the instrument: Local and Remote.
