7.2 Traces
The waveform data can be stored only on external USB
sticks, not internally. Following formats to save the trace
data are possible:
❙ CSV (Comma Separated Values)
In CSV files, curve data is stored in table format. Each
table row is separated by a comma.
Example for CSV file
[Hz],Trace1[dBm]
9.25308,-1.02
9.25308,-7.01
9.25308,-1.02
9.25308,-7.01

9.25308,-7.01
9.25308,-8.01

❙ TXT
TXT files are ASCII files that only contain amplitude values
(no time values). Amplitude values are separated by a
comma. The value pairs are listed as single values without
identification.
Example for TXT file:

9.01,-7.01,-1.02,-7.01
