FORMat

The FORMat command subsystem is used to specify the output format of the readings from the E1563A and E1564A Digitizers.

Subsystem Syntax FORMat

[:DATA] ASCii PACKed REAL [:DATA]?

FORMat[:DATA]

FORMat[:DATA] ASCii PACKed REAL specifies the output format for measurement data.

Comments PACKed Format: PACKed,16 format is signed 16 bits (16-bit integers). Data are returned as raw data and must be converted to voltage by using voltage = reading * range/32768 or voltage = reading * resolution (Use [SENSe:]VOLTage[:DC]:RESolution? to obtain the resolution value).

REAL Format: REAL,64 format returns data as IEEE-754 64-bit real numbers.

IEEE-488.2 Headers: Both PACKed,16 and REAL,64 formats return data preceded by the IEEE-488.2 definite length arbitrary block header. The header is # <num_digits> <num_bytes>, where

•# signifies a block transfer

•<num_digits> is a single digit (1 through 9) which specifies how many digits (ASCII characters) are in <num_bytes>

•<num_bytes> is the number of data bytes which immediately follow the <num_bytes> field.

Reset (*RST) Condition: FORMat:DATA ASCii

FORMat[:DATA]?

FORMat[:DATA]? queries the type of output format set for measurement data. The command returns “ASC,+7”, “PACK,+16”, or “REAL,+64”, where ASC,+& indicates ASCII data with seven significant digits, ASC,+7 indicates ASCII data with seven significant digits, PACKed,+16 indicates the format is signed 16 bits, and REAL,+64 indicates data is IEEE-754 64-bit real numbers.
