Chapter 3 Programming Your Universal Counter for Remote Operation

Overview of Response Message Formats

3-18 Programming Guide

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

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.
