18-3 :FORMat Subsystem

18-3 :FORMat Subsystem
This subsystem contains commands that determine the formatting of numeric data when it is
transferred. The format setting affects data in specific commands only. If a command is
affected, it is noted in the command description.
:FORMat[:READings][:DATA] ASCii|INTeger,32|REAL,[<length>]
:FORMat[:READings][:DATA]?
Title: Numeric Data Format
Description: This command specifies the format in which data is returned in certain
18-6
commands. The optional <length> parameter is needed for REAL
format only. It defines the
length of the floating point number in bits. Valid values are 32 and 64.
If no length is specified, the default length of REAL data is set to 64
bits.
ASCii format returns the data in comma-separated ASCII format. The
units are
dBm for RF Spectrum, % for AM Audio Spectrum/Waveform, Hz for FM
Audio Spectrum/Waveform, Radians for PM Audio
Spectrum/Waveform.
This format requires many more bytes so it is the slowest format.
INTeger,
32 values are signed 32-bit integers in little-endian byte order. This
format
returns the data in 4-byte blocks. The units are mdBm for RF Spectrum,
1000*% for AM Audio Spectrum/Waveform, Hz for FM Audio
Spectrum/Waveform, milli-Radians for PM Audio Spectrum/Waveform.
For example, if the measured result was -12.345 dBm, that value would
be sent as -12345. REAL,32 values are 32-bit floating point numbers
conforming to the IEEE 754 standard in little-endian byte order. This
format returns the data in 4-byte binary format. The units are dBm for
RF Spectrum, % for AM Audio Spectrum/Waveform,
Hz for FM Audio Spectrum/Waveform, Radians for PM Audio
Spectrum/Waveform.
REAL,64 values are 64-bit floating point numbers conforming to the
IEEE 754 standard in little-endian byte order. This format returns the
data in 8-byte binary format. The units are dBm for RF Spectrum, % for
AM Audio Spectrum/Waveform, Hz for FM Audio Spectrum/Waveform,
Radians for PM Audio Spectrum/Waveform.
