Reading/Writing Measurement Data

Entering Data in a Trace

Entering Data in a Trace
By using "Formatted data array" on page 70, you can change the data/memory trace on the
LCD by writing the new data into the "Formatted memory arrays" on page 70.
When you write data into the formatted data/memory array, you can choose either the
ASCII or binary transfer format (see "Data Types for Data Transfer" on page 60).
Example 4-3, Example 4-4, Example 4-3, and Example 4-4 show sample programs that
demonstrate how to write data into formatted data arrays. The sample program in Example
4-3 uses the ASCII transfer format, while the sample in Example 4-4 uses the binary
transfer format.
These sample programs write the trace data of phase noise measurements stored in a file on
the formatted data arrays.
