Notational conventions in this command reference

This section describes the rules to read the description of the commands in this chapter.
Syntax
Part with heading "Syntax" describes the syntax to send a command from the external
controller to the 4294A. A syntax consists of a command part and a parameter part. The
separator between the command part and the parameter part is a space.
If there are several parameters, the separator between adjacent parameters is a comma (,). 2
points (..) between commas indicate that parameters in that part are omitted. For example,
<numeric1>,..,<numeric4> indicates that 4 parameters,
<numeric1>,<numeric2>,<numeric3>,<numeric4>, are required. String-type parameters,
<string>, <string 1>, and so on, must be enclosed in double quotation marks (").
You can omit any lowercase letters in syntax. For example, ":PROGram:CATalog?" on
page 464 can be shortened as ":PROG:CAT?".
The definition of symbols used in the syntax is as follows:
<>
Characters enclosed in this pair of symbols are necessary parameters
when sending the command.
[]
Part enclosed in this parenthesis pair can be omitted.
{}
Part enclosed in this parenthesis pair indicates that you must select one
of the items in this part. Individual items are separated by pipes (|).

Description

Part with heading "Description" describes how to use the command or the operation when
executed.

Parameters

Part with heading "Parameters" describes necessary parameters when sending the
command. When a parameter is a value type or a string type enclosed with <>, its
description, allowable setting range, initial value, and so on are given; when a parameter is
a selection type enclosed with { }, the description of each selection item is given.

Query response

Part with heading "Query response" describes the data format read out when query
(reading out data) is available with this command.
Each readout parameter is enclosed with {}. If there are several items within {} separated
by the pipe (|), only one of them is read out.
When several parameters are read out, they are separated with a comma (,). Note that, 2
points (..) between commas indicate that the data of that part is omitted. For example,
{numeric1},..,{numeric4} indicates that 4 data items, {numeric1}, {numeric2},
{numeric3}, and {numeric4}, are read out.
<newline><^END> after the parameters is the program message terminator.
