HP 132A, 53131A manual Overview of Response Message Formats

	Chapter 3 Programming Your Universal Counter for Remote Operation
	Overview of Response Message Formats
	Table 3-3. Response Message Data Types (Continued)
Type	Description
<Boolean>	A single ASCII-encoded byte, 0 or 1, is returned for the query of settings that use
	<Boolean> parameters.
<literal>	ASCII-encoded bytes corresponding to the short form of the literal used as the
	command parameter.
	For example, if the :CALC3:AVER:TYPE MAXimum command is sent to the
	Counter, the :CALC3:AVER:TYPE? response would be MAX.
<string>	A string response consists of ASCII characters enclosed by double quotes.
	For example, string data is used for the “<error description>”portion of
	:SYST:ERR? response and for [:SENS]:FUNC? response.
<definite length	The syntax is a pound sign (#) followed by a non-zero digit representing the
block>	number of digits in the subsequent decimal integer. The decimal integer specifies
	the number of 8-bit data bytes being sent. This is followed by the actual data.
	The terminator is a line feed asserted with EOI. For example, for transmitting 8
	bytes of data, the format might be:
	The “2”indicates the number of digits that follow and the two digits “08”indicate
	the number of data bytes to be transmitted.
	A zero-length block has the format: #0<new line>^EOI
	<new line> is defined as a single ASCII-encoded byte corresponding to
	10 decimal.
