1.1. About Commands & Queries

This section lists and describes the remote control commands and queries recognized by the
instrument. All commands and queries can be executed in either local or remote state.

The description for each command or query, with syntax and other information, begins on a new
page. The name (header) is given in both long and short form, and the subject is indicated as a
command or query or both. Queries perform actions such as obtaining information, and are
recognized by the question mark (?) following the header.

1.1.1. How they are listed

The descriptions are listed in alphabetical order according to their short form.

1.1.2. How they are described

In the descriptions themselves, a brief explanation of the function performed is given. This is
followed by a presentation of the formal syntax, with the header given in Upper-and-Lower-Case
characters and the short form derived from it in ALL UPPER-CASE characters. Where applicable,
the syntax of the query is given with the format of its response.

1.1.3. When can they be used?

The commands and queries listed here can be used for 4050 Series arbitrary/function waveform
generators.

1.1.4. Command Notation

The following notation is used in the commands:
< > Angular brackets enclose words that are used

2

placeholders, of which there are two types: the header path
and the data parameter of a command.
:= A colon followed by an equals sign separates a placeholder
from the description of the type and range of values that
may be used in a command instead of the placeholder.
{ } Braces enclose a list of choices, one of which one must be
made.
[ ] Square brackets enclose optional items.
… An ellipsis indicates that the items both to its left and right
may be repeated a number of times.

1.3. IEEE 488.2 Common Command Introduction

IEEE standard defines the common commands used for querying the basic information of the
instrument or executing basic operations. These commands usually start with "*" and the length of
the keywords of the command is usually 3 characters.

1.3.1 CHDR

DESCRIPTION This Command is used to change query command return format.

SHORT parameter is return short format. LONG parameter is return long

format. Off is that command header and parameter unit will not return.

COMMAND SYNTAX Comm_HeaDeR <parameter>
<parameter>:= {SHORT,LONG,OFF}

QUERY SYNTAX Comm_HeaDeR?

RESPONSE FORMAT SYNC <parameter>

EXAMPLE 1 Set query command format to long.
CHDR LONG

EXAMPLE 2 Read query command format.
CHDR?
return:
COMM_HEADER LONG

1.3.2 OPC

DESCRIPTION The *OPC (OPeration Complete) command sets to true the OPC bit (bit 0)

in the standard Event Status Register (ESR).
The *OPC? query always responds with the ASCII character 1 because
the de vi c e only responds to the query when the
previous command has been entirely executed.

QUERY SYNTAX *OPC?

RESPONSE FORMAT *OPC 1

1.3.3 IDN

DESCRIPTION The *IDN? Query causes the instrument to identify itself. The response

comprises manufacturer, m o de l number, serial number, software version
and firmware version.

QUERY SYNTAX *IDN?

RESPONSE FORMAT *IDN ,<device id>,< m o de l >,<serial

number>,<software>,<version>,<firmware version>
<device id>： =“BK Precision” is used to identify instrument.
<model>:= A m o de l ide ntifier less than 14 characters.
<serial number>:= A nine- or 10-digit decimal code .
<software version>:= A serial numbers about software version.

<firmware version>:= two digits giving the major release level followed
by a period, then one digit giving the minor release level followed by a
period and a single-digit update level (xx.y.z).

EXAMPLE 1 Reads version information.

*IDN?
return:
*IDN BK Precision,4054,00-00-00-13-22,1.01.01.10R1,20.234.3.

1.4. Output Command

DESCRIPTION Enable or disable the output of the [Output] connector at the front panel
corresponding to the channel.
The query returns ON or OFF.

COMMAND SYNTAX <channel>: OUTPut <parameter>
<channel>:={C1,C2}

<parameter >:= {a parameter from the table belo w}

where: <load>:= {50(default unit is ohm), HZ}

QUERY SYNTAX <channel>: OUTPut?

RESPONSE FORMAT <channel>:OUTPut <load>

EXAMPLE 1 Turns on channel one.

C1:OUTP ON

EXAMPLE 2 Reads channel one ou tp ut state.

C1:OUTP?

return:

C1:OUTP ON,LOAD,HZ

EXAMPLE 4 Set the load to 50Ω
C1:OUTP LOAD,50
