TRACE - Receiver R&S ESCI
1166.6004.12 4.66 E-2
TRACE side menu:
MIN HOLD
The MIN HOLD softkey activates the min peak detector. R&S ESCI saves for
each scan the smallest of the previously stored/currently measured values in
the trace memory.
This function is useful e.g. for making an unmodulated carrier in a composite
signal visible. Noise, interference signals or modulated signals are
suppressed by the min hold function whereas a CW signal is recognized by
its constant level.
Pressing the MIN HOLD softkey again clears the trace memory and restarts
the min hold function.
IEC/IEEE-bus command DISP:WIND:TRAC:MODE MINH
ASCII FILE
EXPORT
The ASCII FILE EXPORT softkey stores the active trace in ASCII format on a
floppy disk.
IEC/IEEE command FORM ASC;
MMEM:STOR:TRAC 1,'TRACE.DAT'
The file consists of the header containing important scaling parameters,
several data sections containing the scan settings 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 for the scan ranges starts with the keyword "Scan <n>:",
(<n> = number of scan range), followed by the scan data in one or several
columns which are also separated by a semicolon.
The data section for the trace date starts with the keyword " Trace <n> " (<n>
= number of stored trace), followed by the measured data in one or several
columns which are also separated by a semicolon.
This format can be read in from spreadsheet calculation programs, e.g. MS-
Excel. It is necessary to define ';' as a separator.
Note: Different language versions of evaluation programs may require a
different handling of the decimal point. It is therefore possible to select
between separators '.' (decimal point) and ',' (comma) using softkey
DECIM SEP.
