CALCulate[1|2|3|4]:WATerfall[:DATA]?
Returns waterfall data that has been transformed to the currently selected coordinate transform (specified
with CALC:FORMat).
Query Syntax:
Example Statements:
Return Format:
If FORMat[:DATA] REAL:
<BLOCK> ::= #<byte>[<length_bytes>] <1st_waterfall_value>
<byte> ::= one byte specifying the number of length
<length_bytes> ::= number of data bytes to follow
If FORMat[:DATA] ASCii:
<BLOCK> ::= <1st_waterfall_value> . .
Attribute Summary:
Description:
This query returns a definite length block of coordinate-transformed waterfall data.
The trace specifier CALCulate [1|2|3|4] determines which waterfall you are selecting. Omit the specifier
or send 1 for trace box A, 2 for trace box B, 3 for trace box C, or 4 for trace box D.
A waterfall consists of a series of traces. To determine the number of traces in the waterfall, divide the
number of values in the waterfall (<length_bytes> / 8) by the number of values in the trace
(CALC:DATA:HEADer:POINts?).
The block is returned as a series of amplitude values (<1st_trace_1st_Y-axis_value>, . . .
<last_trace_last_Y-axis_value>). The unit for these values is the same as the reference level unit. To
determine the unit, send DISP:TRAC:Y:BOTT? UNIT.
For orbit diagrams (CALC:FEED 'XVOL:VOLT [1,2|1,3|1,4|3,4]') the block is a series of real-value
pairs (<1st_trace_1st_X-axis_value>, <1st_trace_1st_Y-axis_value>, . . . <last_trace_last_X-axis_value>,
<last_trace_last_Y-axis_value>).
For Nyquist diagrams (CALC:FORM NYQ) the block is a series of real and imaginary pairs
(<1st_trace_1st_real_value>, <1st_trace_1st_imaginary_value>, . . . <last_trace_last_real_value>,
<last_trace_last_imaginary_value>).
