Format Data: Numeric Data (Remote Command Only)
This command specifies the format of the trace data input and output. It specifies the formats used for
trace data during data transfer across any remote port. It affects only the data format for setting and
querying trace data for the :TRACe[:DATA], TRACe[:DATA]?, :CALCulate:DATA[n]? and FETCh:SANalyzer
[n]? commands and queries.
Remote Command
:FORMat[:TRACe][:DATA] ASCii|INTeger,32|REAL,32 |REAL,64
:FORMat[:TRACe][:DATA]?
Notes
The query response is:
ASCii: ASC,8
REAL,32: REAL,32
REAL,64: REAL,64
INTeger,32: INT,32
When the numeric data format is REAL or ASCii, data is output in the current Y Axis unit. When the
data format is INTeger, data is output in units of m dBm (.001 dBm).
The INT,32 format returns binary 32-bit integer values in internal units (m dBm), in a definite length
block.
Dependencies
Sending a data format spec with an invalid number (for example, INT,48) generates no error. The
analyzer simply uses the default (8 for ASCii, 32 for INTeger, 32 for REAL).
Sending data to the analyzer which does not conform to the current FORMat specified, results in an
error. Sending ASCII data when a definite block is expected generates message –161 "Invalid Block
Data" and sending a definite block when ASCII data is expected generates message –121 "Invalid
Character in Number".
Preset
ASCii
Backwards Compatibility
Notes
Note that the INT,32 format is only applicable to the command, TRACe:DATA. This preserves
backwards compatibility for the Swept SA measurement. For all other commands/queries which
honor FORMat:DATA, if INT,32 is sent the analyzer will behave as though it were set to REAL,32.
