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.

Frequency counter mode.

DEF

Set configuration to default.

HFR

<hfr>

Turn HFR on or off

Note: To use this function, you must turn on the frequency counter.

You can only set the mode, def and hfr from the above list. The rest of the

parameters are for query only.

where: <state>:= {ON|OFF}

<frequency>:= {Input signal frequency.} <duty>:={ Input signal duty.} <trig level>:= { Input signal trig level.} <positive width>:= { Input signal positive width.} <negative width>:= { Input signal negative width.} <mode>:={AC|DC} <default>:= { Set configuration to default.} <hfr>:= {ON|OFF}

EXAMPLE 1 set trig level to 2v.

FCNT TRG, 2v

EXAMPLE 2 get signal frequency.

1.18. Store list command

DESCRIPTION This command is used to read the device wave data name. If the store

unit is empty, the command will return “EMPTY” string.

Note: M50~ M59 is user defined memory. The name will return what you defined it’s not defined,

the name will “E M PT Y”.
