1 Introduction

This manual is for Power Meter models PW3336(-01, -02, -03) and PW3337(-01, -02, -03).

Messages are provided in the interface to control the Power Meter. There are two types of messages: program messages that are sent from the controller (such as a computer) to the Power Meter and response messages that are sent from the Power Meter to the controller. There are also execution confirmation messages for synchronization with the controller in the RS-232C interface.

Message types are further categorized as follows.

Program Messages

Messages Response Messages

Execution Confirmation Messages

When issuing commands that contain data, make sure that the data is provided in the specified format.

When connecting via LAN, connect to TCP/IP port 3300.

Command Messages

Query Messages

During communication the Power Meter will enter the Remote state and the REMOTE Indicator on the unit will turn ON. When this occurs, all operation keys except for SHIFT(EXIT/LOCAL) will be disabled.

However, if the Power Meter is in the Local Lock Out state via GP-IB (GP-IB command LLO:Local Lock Out ->

P.12), the SHIFT(EXIT/LOCAL) Key will also be disabled. If this occurs, execute the GTL (Go To Local)

interface function or turn the Power Meter OFF and ON again to return to the Local state.

If the Power Meter enters the Remote state when on the settings screen, it will automatically change to the measurement display.

PW3336A987-01

Message Format



Program Messages

Program messages can be either Command Messages or Query Messages.

(1) Command Messages

Instructions to control the instrument, such as to change settings or reset

Example: Instruction to set the voltage range (ch1).

:VOLTAGE1:RANGE 300

Header portion Space Data portion

(2) Query Messages

Requests for responses relating to results of operation or measurement, or the state of instrument settings

Example: Request for the current measurement range

:VOLTAGE1:RANGE?

See: "Headers (p. 2)", "Separators (p. 3)", "Data Formats (p.4)"

 Response Messages

When a query message is received, its syntax is checked and a response message is generated.The :HEADer command determines whether headers are prefixed to response messages.

Header ON :VOLTAGE1:RANGE 300

Header OFF 300

At power-on, Header ON is selected. If an error occurs when a query message is received, no response message is generated for that query.

 Command Syntax

Command names are chosen to mnemonically represent their function, and can be abbreviated. The full command name is called the “long form”, and the abbreviated name is called the “short form”. The command references in this manual indicate the short form in upper-case letters, extended to the long form in lower case letters, although the commands are not case-sensitive in actual usage.

DISPLAY? DISP? DISPL? DIS?

Response messages generated by the instrument are in long form and in upper case letters.

 Headers

Headers must always be prefixed to program messages.

(1) Command Program Headers

There are three types of commands: Simple, Compound, and Standard.

• Headers for Simple Commands

This header type is a sequence of letters and digits.

:ESE0

• Headers for Compound Commands

These headers consist of multiple simple command type headers separated by colons ":".

:VOLTage1:RANGE

Header portion Question mark

(The current voltage range for ch1 is 300 V.)

• Headers for Standard Commands

This header type begins with an asterisk "*", indicating that it is a standard command defined by IEEE 488.2.

*RST

(2) Query Program Header

These commands are used to query the instrument about the results of operations, measured values, and the current states of instrument settings. As shown in the following examples, a query is formed by appending a question mark ? after a program header.

:HOLD? :VOLTage:RANGe?

Characters within square brackets [ ] may be omitted.

Either form is valid

:MEASure[:NORMAL]:VALue? :MEASure:VALue?



Message Terminators

The instrument recognizes the following message terminators (delimiters):

Depending on the instrument's interface settings, the following can be selected as the terminator for response messages. For information on settings, see "Terminator Setting" (p. 107).



Separators

(1) Message Unit Separator

Multiple messages can be written in one line by separating them with semicolons ";".

:VOLTage1:RANGe 300;:AVERaging 10

• When messages are combined in this way and if one command contains an error, all subsequent messages up to the next terminator will be ignored.

(2) Header Separator

In a message consisting of both a header and data, the header is separated from the data by a space “ ” (ASCII code 20H).

: VOLTage1: RANGe 300

(3) Data Separator

In a message containing multiple data items, commas are required to separate the data items from one another.

:MEASure? U1, I1

PW3336A987-01

The instrument does not completely support IEEE 488.2. Use referenced data whenever possible. Also be careful not to overflow the input buffer or output queue with a single command.



Data Formats

The instrument uses character data, decimal numeric data and character string data depending on the command.

(1) Character Data

Character data always begins with an alphabetic character, and subsequent characters may be either alphabetic or numeric. Character data is not case-sensitive, although response messages from the instrument are only upper case. When the command data portion contains <1/0/ON/OFF>, the operation will be the same as when 0 is OFF and 1 is ON.

:HEADER OFF

(2) Decimal Numeric Data

Three formats are used for numeric data: NR1, NR2 and NR3. Numeric values may be signed or unsigned. Unsigned numeric values are handled as positive values. Values exceeding the precision handled by the instrument are rounded to the nearest valid digit.

NR1 Integer data (e.g.: +12, -23, 34)

•

NR2 Fixed-point data (e.g.: +1.23, -23.45, 3.456)

•

NR3 Floating-point exponential representation data (e.g.: +1.0E-2, -2.3E+4)

•

The term “NRf format” includes all three of the above numeric decimal formats.

The instrument accepts NRf format data. The format of response data is specified for each command, and the data is sent in that format.

:AVERAGING 10

Compound Command Header Omission

When several commands having a common header are combined to form a compound command (for example, :VOLTage1:AUTO and :VOLTage1:RANGe), if they are written together in sequence, the common portion (here, :VOLTage1:) can be omitted after its initial occurrence. This common portion is called the “current path” (analogous to the path concept in computer file storage), and until it is cleared, the interpretation of subsequent commands presumes that they share the same common portion.

This usage of the current path is shown in the following example:

Full expression

:VOLTage1:AUTO OFF;:VOLTage1:RANGe 300

Compacted expression

:VOLTage1:AUTO OFF;RANGe 300

The current path allows you to abbreviate the next command.

The current path is cleared when the power is turned on, when reset by key input, by a colon “:” at the start of a command, and when a message terminator is detected. Standard command messages can be executed regardless of the current path. They have no effect upon the current path.

A colon “:” is not required at the start of the header of a Simple or Compound command. However, to avoid confusion with abbreviated forms and operating mistakes, we recommend always placing a colon at the start of a header.

PW3336A987-01

• Power on

• Device clear

• Query error

Output Queue and Input Buffer

 Output Queue

Response messages are stored in the output queue until read by the controller. The output queue is also cleared in the following circumstances:

The output queue capacity of the instrument is 4,096 bytes. If response messages overflow the buffer, a query error is generated and the output queue is cleared.

 Input Buffer

The input buffer capacity of the instrument is 1,024 bytes. If 1,024 bytes are allowed to accumulate in this buffer so that it becomes full, the GP-IB interface bus enters the waiting state until space is cleared in the buffer. The RS-232C and LAN interfaces will not accept data beyond 1,024 bytes.

Note: Ensure that the length of a single line never exceeds 1,024 bytes.

Service Request Enable Register (SRER)

Status Byte Register

The instrument uses the status model defined by the IEEE 488.2 standard for items related to serial polling via the service request function. Events are what trigger service requests.

Standard Event Register Description

Service Request Output Queue data information SRQ occurrence Each of these bits correspond to a specific event register

Overview of Service Request Occurrence

The Status Byte Register contains information about the event registers and the output queue. Required items are selected from this information by masking with the Service Request Enable Register. When any bit selected by the mask is set, bit 6 (MSS; the Master Summary Status) of the Status Byte Register is also set, which generates an SRQ (Service Request) message and dispatches a service request.

SRQs (Service Requests) can be used only with the GP-IB interface. However, SRER setting (*SRE?) and STB read (*STB?) queries can be used even with the RS-232C and LAN interfaces.

PW3336A987-01

Bit 7

This is the logical sum of the other bits of the Status Byte Register.

Bit 5

ESB

Standard Event Status (logical sum) bit This is the logical sum of the Standard Event Status Register.

Bit 4

MAV

Bit 3

ESB3

Event Summary (logical sum) bit 3 This is the logical sum of Event Status Register 3.

Bit 2

ESB2

Event Summary (logical sum) bit 2 This is the logical sum of Event Status Register 2.

Bit 1

ESB1

Event Summary (logical sum) bit 1 This is the logical sum of Event Status Register 1.

Bit 0

ESB0

Event Summary (logical sum) bit 0 This is the logical sum of Event Status Register 0.



Status Byte Register (STB)

During serial polling, the contents of the 8-bit Status Byte Register are sent from the instrument to the controller. When any Status Byte Register bit enabled by the Service Request Enable Register has switched from 0 to 1, the MSS bit becomes 1. Consequently, the SRQ bit is set to 1, and a service request is dispatched.

The SRQ bit is always synchronous with service requests, and is read and simultaneously cleared during serial polling. Although the MSS bit is only read by an *STB? query, it is not cleared until a clear event is initiated by the

*CLS command.

 Service Request Enable Register (SRER)

Setting a bit of this register to 1 enables the corresponding bit of the Status Byte Register to be used.

PW3336A987-01

Bit 7

PON

Power-On Flag

Set to 1 when the power is turned on, or upon recovery from an outage.

Bit 6

URQ

Command error (The command to the message terminator is ignored.)

This bit is set to 1 when a received command contains a syntactic or semantic error:

• Program header error

• Incorrect number of data parameters

• Invalid parameter format

• Received a command not supported by the instrument

Bit 4

EXE

Execution Error

This bit is set to 1 when a received command cannot be executed for some reason.

• The specified data value is outside of the set range

• The specified data cannot be set (data format discrepancy)

• Execution is prevented by some other operation being performed

Bit 3

DDE

Device-dependent Error

This bit is set to 1 when a command cannot be executed due to some reason other than a command error, a query error or an execution error.

• An internal error occurred and execution cannot be performed (error

displayed)

• A command was received that cannot be executed during a restricted

operation (integration, hold, etc.)

• When "o.r",”S.Err” or ”-----“ occurs and the error data is read by a *MEASure?

query.

Bit 2

QYE

Query Error (the output queue is cleared)

This bit is set to 1 when a query error is detected by the output queue control.

• When an attempt is made to read the output queue when the output queue is

empty (GP-IB only)

• When the data overflows the output queue

• When the next command is received while there is data in the output queue

• When there is a query after a *IDN? on the same line.

Bit 1

RQC

(unused)

Request Control

Bit 0

OPC

Operation Complete

This bit is set to 1 in response to an *OPC command.

• It indicates the completion of operations of all messages up to the *OPC

command

Event Registers

 Standard Event Status Register (SESR)

The Standard Event Status Register is an 8-bit register. If any bit in the Standard Event Status Register is set to 1(after masking by the Standard Event Status Enable Register), bit 5 (ESB) of the Status Byte Register is set to 1.

See: “

Standard Event Status Enable Register (SESER)” (p.

The Standard Event Status Register is cleared in the following situations:

• When a *CLS command is executed

• When an event register query

• When the instrument is powered on

(

*ESR?) is executed

Standard Event Status Register (SESR) and Standard Event Status Enable Register (SESER)

 Device-specific Event Status Registers (ESR0, ESR1, ESR2,

and ESR3)

This instrument provides four Event Status Registers for controlling events. Each event register is an 8-bit register.

When any bit in one of these Event Status Registers enabled by its corresponding Event Status Enable Register is set to 1, the following happens:

• For Event Status Register 0, bit 0 (ESB0) of the Status Byte Register (STB) is set to 1.

• For Event Status Register 1, bit 1 (ESB1) of the Status Byte Register (STB) is set to 1.

• For Event Status Register 2, bit 2 (ESB2) of the Status Byte Register (STB) is set to 1.

• For Event Status Register 3, bit 3 (ESB3) of the Status Byte Register (STB) is set to 1.

Event Status Registers 0 through 3 are cleared in the following situations:

• When a *CLS command is executed

• When an Event Status Register query (

• When the instrument is powered on

:ESR0?, :ESR1?, :ESR2?

, or

:ESR3?

) is executed

Command execution time indicates the time for analyzing and processing long form commands. However, the command execution time for commands with data is the time described according to the data format specified in the <data portion>, and for query commands it is the time when the header is ON.

 The instrument performs measurements, calculations, and updates the display repeatedly in 200 ms cycles.

Measurements and calculations are given priority over command processing, and require a maximum of 150 ms. Therefore, a maximum delay of 150 ms may be encountered from the time a command is received until analysis begins.

• Updating the display may be delayed if the analysis processing is not completed in time, even if the internal

processing time is met.

• All commands are sequential.

• When communicating with a controller, the time required to transfer the data must be added.

The amount of time required for the data transfer depends on the controller (communications). The RS-232C transfer time for a starting bit, data length of 8, no parity bit, and a stop bit (10 bits total) with a baud rate setting of N bps is calculated as follows:

Transfer Time T [1 character/second] = Baud Rate N [bps] / 10 [bits] The measurement value is 11 characters so the time required to transfer one piece of data would be 11/T. (Example) 9600 bps: 11 / (9600 / 10) = 11 ms (approximately)

• Wait a few moments after making any changes via setting commands to allow the measurements to stabilize.

Errors During Communications

An error occurs when messages are executed in the following cases:

• Command Error

When message syntax (spelling) is invalid When the data format in a command or query is invalid

• Query Error

When the response message exceeds 4,000 bytes When there is a query after an

• Execution Error

When invalid character or numeric data is present

• Device-dependent Error

When an error occurs during self-testing When a restricted operation (such as changing the range) is attempted during an integration operation (when the INTEGRATOR indicator is lit or flashing) When a restricted operation (such as changing the range) is attempted during the Hold state
