Reading Out Trace Data
In the following example, the trace data obtained with the default setting is read
from the instrument and displayed in a list on the screen. Readout occurs first in
binary format and then in ASCII format, once with the span > 0 and once with the
span = 0.
In binary format, the header of the message with the length specification is evalu-
ated and used to calculate the x-axis values.
In ASCII format, merely the list of level values is output.
Binary data is read out in three steps:
1. The number of digits in the length specification is read out.
