T1-T3->T1
The T1-T3->T1 softkey enables the trace maths expression to substract Trace3 from
Trace1 and copies the results into Trace1.

MIN HOLD
The MIN HOLD softkey activates the minhold mode for the collected measured values
for the active trace, ie the minimum value of each point in the trace is determined over
the requested number of sweeps.

ASCII FILE EXPORT
The ASCII FILE EXPORT softkey stores the active trace in ASCII format on a floppy
disk.
The file consists of the header containing important scaling parameters and a data
section containing the trace data.
The data of the file header consist of three columns, each separated by a semicolon:
parameter name; numeric value; basic unit
The data section starts with the keyword " Trace;<n>;" (<n> = number of stored trace),
followed by the measured data in two columns which are also separated by a
semicolon. The first column contains the frequency value, the second contains the
corresponding Phase noise value.
This format can be read in from spreadsheet calculation programs, eg MSExcel.
It is necessary to define ’;’ as a separator.
Different language versions of evaluation programs may require a different handling of
the decimal point. It is therefor
e possible to select between separators ’.’ (decimal
point) and ’,’ (comma) using softkey DECIM SEP.
