4.1.12 Trace Data I/O
Trace data on the screen includes data for 501 points on the frequency axis. To input and output this data,
it is necessary to transfer data in order for all 501 points, starting from the left most point (start frequency).
Each point level is expressed by an integer from 512 to 3392 (however, when the trace exceeds the upper
limit of the vertical scale, a value greater than 3392 is transferred).
