Table 3-3. Response Message Data Types (Continued)

Type Description

<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

block>

The syntax is a pound sign (#) followed by a non-zero digit representing the 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.

<new line><8 bytes of data>2# 08 ^EOI
