If the spectrogram display is selected when you perform this function, the entire histo-
gram buffer with all frames is exported to a file. The data corresponding to a particular
frame begins with information about the frame number and the time that frame was
recorded. For large history buffers the export operation may take some time.
For details see Chapter 3.10.4, "ASCII File Export Format for Spectrograms",
on page 561.

Decim Sep
Selects the decimal separator with floating-point numerals for the ASCII Trace export
to support evaluation programs (e.g. MS-Excel) in different languages. The values '.'
(decimal point) and ',' (comma) can be set.

Trace Math
Opens the "Trace Mathematics" dialog box to define which trace is subtracted from
trace 1. The result is displayed in trace 1 and refers to the zero point defined with the
Trace Math Position softkey. The following subtractions can be performed:
"T1"->"T1"-"T2" Subtracts trace 2 from trace 1.
"T1"->"T1"-"T3" Subtracts trace 3 from trace 1
"T1"->"T1"-"T4" Subtracts trace 4 from trace 1
"T1"->"T1"-"T5" Subtracts trace 5 from trace 1
"T1"->"T1"-"T6" Subtracts trace 6 from trace 1
To switch off the trace math, use the Trace Math Off softkey.

Trace Math Mode
Opens a submenu to select the mode for the trace math calculations.
Lin ← Trace Math Mode
Activates linear subtraction, which means that the power level values are converted
into linear units prior to subtraction. After the subtraction, the data is converted back
into its original unit.
This softkey takes effect if the grid is set to a linear scale (see Range softkey). In this
case, subtraction is done in two ways (depending on the set unit – see Unit softkey):
●
The unit is set to either W or dBm: the data is converted into W prior to subtraction,
i.e. averaging is done in W.
