1.2.1 Connecting the Instrument to the Network

NOTICE Risk of network failure

Before connecting the instrument to the network or configuring the network, consult your network administrator. Errors may affect the entire network.

Thenetworkcardcanbeoperatedwitha10MbpsEthernetIEEE802.3ora100MbpsEthernetIEEE 802.3u interface.

NOTICE To establish a network connection, connect a commercial RJ-45 cable to one of the

LAN ports of the instrument and to a PC.

NOTICE Risk of network errors Connection errors can affect the entire network. If your network does not support

DHCP, or if you choose to disable dynamic TCP/IP configuration, you must assign valid address information before connecting the instrument to the LAN. Contact your net-work administrator to obtain a valid IP address.

1.4 Messages and Command Structure

1.4.1 Messages

Instrument messages are employed in the same way for all interfaces, if not indicated otherwise in the description.See also:• Structureandsyntaxoftheinstrumentmessages:chapter1.4.2,„SCPICommandStructure“.• Detaileddescriptionofallmessages:chapter 2, „Command Reference“.

There are different types of instrument messages:• Commands• Instrument responses

CommandsCommands (program messages) are messages which the controller sends to the instrument. Theyoperatetheinstrumentfunctionsandrequestinformation.Thecommandsaresubdividedaccording to two criteria:

According to the instrument effect:• Setting commands cause instrument settings such as a reset of the instrument or setting the

frequency. • Queriescausedatatobeprovidedforremotecontrol,e.g.foridentificationoftheinstrumentorpollingaparametervalue.Queriesareformedbyappendingaquestionmarktothecom-mand header.

Basics


According to their definition in standards:• ThefunctionandsyntaxoftheCommoncommandsarepreciselydefinedinstandardIEEE

488.2. They are employed identically on all instruments (if implemented). They refer to func-tions such as management of the standardized status registers, reset and self test.

• Instrument control commands refer to functions depending on the features of the instrument suchasvoltagesettings.ManyofthesecommandshavealsobeenstandardizedbytheSCPIcommittee.Thesecommandsaremarkedas„SCPIcompliant“inthecommandreferencechapters.CommandswithoutthisSCPIlabelaredevice-specific,however,theirsyntaxfollowsSCPIrulesaspermittedbythestandard.

Instrument responsesInstrumentresponses(responsemessagesandservicerequests)aremessageswhichtheinstru-ment is sent to the controller after a query. They can contain measurement results, instrument settings and information on the instrument status.

12.1.6.1 Structure of a SCPI Status Register

Each standard SCPI register consists of 5 parts. Each part has a width of 16 bits and has different functions. The individual bits are independent of each other, i.e. each hardware status is assigned a bit number which is valid for all five parts. Bit 15 (the most significant bit) is set to zero for all parts. Thus the contents of the register parts can be processed by the controller as positive integers.

Fig. 12-1: The status-register model

Description of the five status register parts

The five parts of a SCPI register have different properties and functions:

● CONDitionThe CONDition part is written into directly by the hardware or the sum bit of the nextlower register. Its contents reflect the current instrument status. This register part canonly be read, but not written into or cleared. Its contents are not affected by reading.

● PTRansitionThe two transition register parts define which state transition of the CONDition part(none, 0 to 1, 1 to 0 or both) is stored in the EVENt part.The Positive-TRansition part acts as a transition filter. When a bit of theCONDition part is changed from 0 to 1, the associated PTR bit decides whether theEVENt bit is set to 1.– PTR bit =1: the EVENt bit is set.

– PTR bit =0: the EVENt bit is not set.

This part can be written into and read as required. Its contents are not affected byreading.

● NTRansitionThe Negative-TRansition part also acts as a transition filter. When a bit of theCONDition part is changed from 1 to 0, the associated NTR bit decides whether theEVENt bit is set to 1.– NTR bit =1: the EVENt bit is set.

– NTR bit =0: the EVENt bit is not set.

● STB, SREThe STatus Byte (STB) register and its associated mask register Service RequestEnable (SRE) form the highest level of the status reporting system. The STB providesa rough overview of the instrument status, collecting the information of the lower-levelregisters.

● ESR, SCPI registersThe STB receives its information from the following registers:– The Event Status Register (ESR) with the associated mask register standard

Event Status Enable (ESE).

– The STATus:OPERation and STATus:QUEStionable registers which aredefined by SCPI and contain detailed information on the instrument.

● Output bufferThe output buffer contains the messages the instrument returns to the controller. Itis not part of the status reporting system but determines the value of the MAV bit inthe STB and thus is represented in the overview.

192User Manual 1305.0595.02 ─ 03

The serial poll method is defined in IEEE 488.1 and used to be the only standard possibility for different instruments to poll the status byte. The method also works for instru-ments which do not adhere to SCPI or IEEE 488.2.

The serial poll is mainly used to obtain a fast overview of the state of several instruments connected to the controller.

Query of an instrument status

Each part of any status register can be read using queries. There are two types of commands:

● The common commands *ESR?, *IDN?, *IST?, *STB? query the higher-level registers.

● The commands of the STATus system query the SCPI registers (STATus:QUEStionable...)

The returned value is always a decimal number that represents the bit pattern of thequeried register. This number is evaluated by the controller program.

Queries are usually used after an SRQ in order to obtain more detailed information on the cause of the SRQ.

Decimal representation of a bit pattern

The STB and ESR registers contain 8 bits, the SCPI registers 16 bits. The contents of a status register are specified and transferred as a single decimal number. To make this possible, each bit is assigned a weighted value. The decimal number is calculated as the sum of the weighted values of all bits in the register that are set to 1.

Example: The decimal value 40 = 32 + 8 indicates that bits no. 3 and 5 in the status register (e.g. the QUEStionable status summary bit and the ESB bit in the STatus Byte ) are set.

Error Queue

Each error state in the instrument leads to an entry in the error queue. The entries of the error queue are detailed plain text error messages that can be looked up in the Error Log or queried via remote control using SYSTem:ERRor[:NEXT]? or SYSTem:ERRor:ALL?. Each call of SYSTem:ERRor[:NEXT]? provides one entry from the error queue. If no error messages are stored there any more, the instrument responds with 0, "No error".

The error queue should be queried after every SRQ in the controller program as the entries describe the cause of an error more precisely than the status registers. Especially
