Vector analyzer mode, digital demodulation
The number of data transferred (except for the symbol table) is determined by the following
formula
number of results = result length * points per symbol
Max. 6400 results can be transferred (for example result length 1600, points per symbol 4).
In all cartesian diagrams (MAGNITUDE CAP BUFFER, MAGNITUDE, PHASE,
FREQUENCY, REAL/IMAG, EYE[I], EYE[Q], ERROR VECT MAGNITUDE) test data are
transferred in the unit selected for display.
FORMAT REAL,32 is to be used for binary transmission.
Note: In the case of the eye pattern, results are simply superimposed in the display, ie
the EYE representation is the same as the REAL/IMAG representation.
In the polar diagrams (POLAR CONSTELL, POLAR VECTOR) the real and the imaginary
component are transferred as a pair for each result.
FORMAT REAL,32 is to be used for binary transmission.
With the SYMB TABLES / ERRORS setting, the displayed symbols can be read out as
traces. Trace assignment is as follows:
Full screen Trace 1
Split screen, screen A: Trace 1
Split screen, screen B: Trace 2
One byte (8 bits) is read out for each symbol.
FORMAT UINT,8 is to be used for binary transmission.
Vector analyzer mode, analog demodulation
The number of results transferred depends on the SWEEP TIME and DEMOD BW
settings. Max. 5000 and min. 10 points are available. The unit for the results depends on
the selected demodulation:
AM unit %
FM unit Hz
PM unit rad or deg
FORMAT REAL,32 is to be used for binary data transmission.
:TRACe:COPY TRACE1| TRACE2| TRACE3| TRACE4 ,
TRACE1| TRACE2| TRACE3| TRACE4
This command copies data from one trace to another. The second operand designates the source,
the first operand the destination of the data to be copied.
Example:
":TRAC:COPY TRACE1,TRACE2"
Features: *RST value:
SCPI:
conforming
Modes: A, VA, BTS, MS
This command is an event and therefore has no query and no *RST value assigned.
