CALCulate
CALCulate[1|2|3|4]:X:DATA?
Returns the X-axis values that correspond to the Y-axis values read with the CALC:DATA? query.
Query Syntax:
Example Statements:
Return Format:
<DEF_BLOCK> ::= #<byte><length_bytes> <1st_X-axis_value> . . .
<byte> ::= number of length bytes to follow (ASCII encoded)
<length_bytes> ::= number of data bytes to follow (ASCII encoded)
<DEF_BLOCK> ::= <1st_X-axis_value> . . .<last_X-axis_value>
Attribute Summary:
Description:
This query returns a definite length block of the X-axis values that correspond to coordinate-transformed
trace data obtained using the CALC:DATA? query.
The trace specifier CALCulate [1|2|3|4] determines which trace you are selecting. Omit the specifier or
send 1 for trace A, 2 for trace B, 3 for trace C, or 4 for trace D.
The block is returned as a series of X-axis values. To determine the unit, send
CALC:MARKer:POSition? UNIT.
For orbit diagrams (CALC:FEED 'XVOL:VOLT [1,2|1,3|1,4|3,4]') the block consists of the time values
(T) for the real-value pairs (<1st_T_value> for <1st_X-axis_value>,
<1st_Y-axis_1_value>, . . . <last_T_value> for <last_X-axis_value>, <last_Y-axis_value>).
For Nyquist diagrams (CALC:FORM NYQ) the block consists of the frequency values for the real and
imaginary pairs.
For polar diagrams (CALC:FORM POL) the block consists of the frequency values for the magnitude and
phase pairs.
In octave analysis instrument mode (INST:SEL OCT;Option 1D1) or for octave data stored in data
registers, the last two values are 9.1E37. They correspond to the X-axis values for the weighted overall
band and the overall band. These values are meaningless.
This query has no command form.
