–999.0 is returned, when not measured/an error
occurs.
If REAL,32, or INTeger,32 is set for :FORMat[:DATA], the output of “#
(ASCII format)” is followed by the output of “Range of character string
indicating byte length of binary data (ASCII format”, “Byte length of
binary data (ASCII format)”, and “Trace data string (binary format)”, in
this order. In the case of the binary format too, the response message
terminator is attached (refer to “1.7.2 SCPI response message format” in
the
MS2690A/MS2691A/MS2692A and MS2830A/MS2840A Signal
Analyzer Operation Manual (Mainframe Remote Control)
.
Example:
If 1001 point trace data is read out when REAL,32 is set for :FORMat[:DATA],
> #44004<4004 bytes of data>
the “4” after “#” indicates that “this is followed by 4 characters indicating
the binary data length.”“4004” indicates that “this is followed by 4004
bytes of binary data.”
