For example: − 24, 353 mdBm converts to − 24.353 dBm.
ASCii - Amplitude values are in amplitude units separated by commas. ASCii
format requires more memory than the binary formats. Handling large amounts
of this type of data, takes more time and storage space.
Integer,32 - Binary 32-bit integer values in internal units (mdBm), in a
definite length block.
Real,32 (or 64 ) - Binary 32-bit (or 64-bit) real values in amplitude units, in a
definite length block. Transfers of real data are done in a binary block format.
For uncorrected trace data ( :TRACe[:DATA] with parameter RAWTRACE ),
UINTeger , and INTeger formats apply to RAWTRACE queries, and return
uncorrected ADC values. The fastest mode is UINTeger,16 .
UINTeger, 16 - Binary 16-bit unsigned integer uncorrected ADC values, in a
definite length block.
Integer,32 - Binary 32-bit unsigned integer uncorrected ADC values in a
definite length block.
A definite length block of data starts with an ASCII header that begins with # and
indicates how many additional trace points are following in the block. Suppose the
header is #512320:
• The first digit in the header (5) tells you how many additional digits/bytes there
are in the header.
• The 12320 means that 12,320 data bytes follow the header.
• Divide this number of bytes by your selected data format bytes/point, either 8
(for Real 64 ), 4 (for Real 32 or Int 32 ), or 2 (for UINT 16 ). In this
example, if you are using Real 64 then there are 1540 trace points in the
block.
