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.
1.3.1 How they are listed
The descriptions are listed in alphabetical order according to their short form.
1.3.2 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.
1.3.3 When can they be used?
The commands and queries listed here can be used for 4050 Series arbitrary/function
waveform generators.
1.3.4 Command Notation
The following notation is used in the commands:
< > Angular brackets enclose words that are used
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 IDN
DESCRIPTION
The *IDN? Query causes the instrument to identify itself. The
response comprises manufacturer, model number, serial number,
software version and firmware version.
QUERY SYNTAX
*IDN?
RESPONSE FORMAT
*IDN ,,,, , ,
：=“BK Precision” is used to identify instrument.
:= A model identifier less than 14 characters.
:= A nine- or 10-digit decimal code .
:= A serial numbers about software 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,4050B,00-00-00-13-22,1.01.01.10R1,20.234.3.
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 device only responds to the query when the
previous command has been entirely executed.
QUERY SYNTAX
*OPC?
4
RESPONSE FORMAT
*OPC 1
1.3.3 CLS
DESCRIPTION
The *CLS command clears all the status data registers.
COMMAND SYNTAX
*CLS
EXAMPLE
The following command causes all the status data registers to be
cleared:
*CLS
1.3.4 ESE
DESCRIPTION
The *ESE command sets the Standard Event Status Enable register
(ESE). This command allows one or more events in the ESR register to
be reflected in the ESB summary message bit (bit 5) of the STB register.
The *ESE? query reads the contents of the ESE register.
COMMAND SYNTAX
*ESE
: = 0 to 255.
QUERY SYNTAX
*ESE?
RESPONSE FORMAT
*ESE
EXAMPLE
The following instructions allows the ESB bit to be set if a user request
(URQ bit 6, i.e. decimal 64) and/or a device dependent error (DDE bit
3, i.e. decimal 8) occurs. Summing these values yields the ESE register
mask 64+8=72.
*ESE?
Return:
*ESE 72
RELATED COMMANDS
*ESR
1.3.5
ESR
DESCRIPTION
The *ESR? query reads and clears the contents of the Event
5
Status Register (ESR). The response represents the sum of the binary
values of the register bits 0 to 7.
QUERY SYNTAX
*ESR?
RESPONSE FORMAT
*ESR
: = 0 to 255
EXAMPLE
The following instruction reads and clears the content of the ESR
register:
*ESR?
Return：
*ESR 0
RELATED COMMANDS
1.3.6
*CLS, *ESE
RST
DESCRIPTION
The *RST command initiates a device reset. The *RST recalls the
default setup.
COMMAND SYNTAX
* RST
EXAMPLE
This example resets the signal generator:
*RST
1.3.7
SRE
DESCRIPTION
The *SRE command sets the Service Request Enable register (SRE).
This command allows the user to specify which summary message
bit(s) in the STB register will generate a service request.
A summary message bit is enabled by writing a ‘1’ into the
corresponding bit location. Conversely, writing a ‘0’ into a given bit
location prevents the associated event from generating a service
request (SRQ). Clearing the SRE register disables SRQ interrupts.
The *SRE? query returns a value that, when converted to a
binary number represents the bit settings of the SRE register. Note
that bit 6 (MSS) cannot be set and it’s returned value is always zero.
COMMAND SYNTAX
*SRE
: = 0 to 255
6
QUERY SYNTAX
*SRE?
RESPONSE FORMAT
*SRE
EXAMPLE
The following instruction allows a SRQ to be generated as soon as the
MAV summary bit (bit 4, i.e. decimal 16) or the INB summary bit (bit 0,
i.e. decimal 1) in the STB register, or both are set. Summing these two
values yields the SRE mask 16+1 = 17.
*SRE?
Return:
*SRE 17
1.3.8
STB
DESCRIPTION
QUERY SYNTAX
The *STB? query reads the contents of the 488.2 defined status
register (STB), and the Master Summary Status (MSS).
The response represents the values of bits 0 to 5 and 7 of the Status
Byte register and the MSS summary message.
The response to a *STB? query is identical to the response of a serial
poll except that the MSS summary message appears in bit 6 in place of
the RQS message.
*STB?
RESPONSE FORMAT
*STB
: = 0 to 255
EXAMPLE
The following reads the status byte register:
*STB?
Return:
*STB 0
RELATED COMMANDS
*CLS, *SRE
1.3.9
TST
DESCRIPTION
The *TST? query performs an internal self-test and the response
indicates whether the self-test has detected any errors. The self-test
includes testing the hardware of all channels.
Hardware failures are identified by a unique binary code in the
returned number. A “0” response indicates that no failures
occurred.
7
QUERY SYNTAX
*TST?
RESPONSE FORMAT
*TST
: = 0 self-test successful
The following causes a self-test to be performed:
TST?
Return(if no failure):
*TST 0

parameter.
CARR, DLY
Value of carrier delay. Only PULSE can set this
parameter.
Note: If Carrier wave is Pulse or Noise, the modulation waveform cannot be set. To set AM,
FM, PM, CARR and STATE the first parameter have to be one of them.
