Safety Summary

Safety Summary

The following general safety precautions must be observed during all phases of operation of this instrument. Failure to comply with these precautions or with specific warnings elsewhere in this manual violates safety standards of design, manufacture, and intended use of the instrument. Agilent Technologies Inc. assumes no liability for the customer's failure to comply with these requirements.

General

This product is a Safety Class 1 instrument (provided with a protective earth terminal). The protective features of this product may be impaired if it is used in a manner not specified in the operation instructions.

All Light Emitting Diodes (LEDs) used in this product are Class 1 LEDs as per IEC 60825-1.

Environmental Conditions

This instrument is intended for indoor use in an installation category II, pollution degree 2 environment. It is designed to operate at a maximum relative humidity of 95% and at altitudes of up to 2000 meters. Refer to the specifications tables for the ac mains voltage requirements and ambient operating temperature range.

Before Applying Power

Verify that the product is set to match the available line voltage, the correct fuse is installed, and all safety precautions are taken. Note the instrument's external markings described under “Safety Symbols” on page 8.

6

Safety Summary

Ground the Instrument

To minimize shock hazard, the instrument chassis and cover must be connected to an electrical protective earth ground. The instrument must be connected to the ac power mains through a grounded power cable, with the ground wire firmly connected to an electrical ground (safety ground) at the power outlet. Any interruption of the protective (grounding) conductor or disconnection of the protective earth terminal will cause a potential shock hazard that could result in personal injury.

Fuses

Only fuses with the required rated current, voltage, and specified type (normal blow, time delay, etc.) should be used. Do not use repaired fuses or short-circuited fuse holders. To do so could cause a shock or fire hazard.

Do Not Operate in an Explosive Atmosphere

Do not operate the instrument in the presence of flammable gases or fumes.

Do Not Remove the Instrument Cover

Operating personnel must not remove instrument covers. Component replacement and internal adjustments must be made only by qualified service personnel.

Instruments that appear damaged or defective should be made inoperative and secured against unintended operation until they can be repaired by qualified service personnel.

General Programming

1 Aspects

This chapter provides general information on writing GP-IB/SCPI programs for instruments like the Agilent 81130A.

Detailed information on programming the Agilent 81130A can be found in

Chapter 2 “Programming Reference” on page 25.

13

General Programming Aspects

The GP-IB Interface Bus

The GP-IB Interface Bus

The GP Interface Bus is the interface used for communication between a controller and an external device, such as the Agilent 81130A. The GP-IB conforms to IEEE standard 488-1987, ANSI standard MC 1.1, and IEC recommendation 625-1.

If you are not familiar with the GP-IB, please refer to the following books:

The Institute of Electrical and Electronic Engineers: IEEE Standard 488.1-1987, IEEE Standard Digital Interface for Programmable Instrumentation.

The Institute of Electrical and Electronic Engineers: IEEE Standard 488.2-1987, IEEE Standard Codes, Formats, and Common Commands for Use with IEEE Standard 488.1-1987.

Modes of

Operation

General Programming Aspects

Agilent 81130A Remote Control

Agilent 81130A Remote Control

You can only set the GP-IB address from the front panel of the instrument (refer to the Quick Start Guide).

The default GP-IB address is 10.

The Agilent 81130A has two modes of operation:

Local

The instrument is operated using the front panel keys.

Remote

After receiving the first command or query via the GP-IB, the instrument is put into remote state. The front panel is locked. To return to local operating mode, press SHIFT (LOCAL).

General Programming Aspects

Programming Recommendations

Programming Recommendations

Here are some recommendations for programming the instrument:

Start programming from the default setting. The common command for setting the default setting is:

*RST

Switch off the automatic update of the display to increase the programming speed. The device command for switching off the display is:

:DISPlay OFF

The SCPI standard defines a long and a short form of the commands. For fast programming speed it is recommended to use the short forms. The short forms of the commands are represented by upper case letters. For example the short form of the command to set 100 ns delay is:

:PULS:DEL 100NS

To improve programming speed it is also allowed to skip optional subsystem command parts. Optional subsystem command parts are depicted in square brackets, e.g.: set amplitude voltage of output 1:

[SOURce]:VOLTage[1][:LEVel][:IMMediate][:AMPLitude]. Sufficient to use: :VOLT 1.2V

For the commands to set the timing and level parameters, except of period/frequency, you can explicitly specify the output to be programmed (for compatibility reasons). If there is no output specified, the commands will set the default output 1.

So, for setting a high level of 3 Volts for output 1 the commands are:

:VOLT:HIGH 3V # sets high level of 3 V at out 1 :VOLT1:HIGH 3V # sets high level of 3 V at out 1

16

General Programming Aspects

Programming Recommendations

It is recommended to test a new setting that will be programmed on the instrument by setting it up manually.

Enable the outputs so that the instrument’s error check system is on and possible parameter conflicts are immediately displayed.

When you have found the correct setting, then use this to create the program. In the program it is recommended to send the command for enabling outputs (for example, :OUTPut ON) as the last command.

Selftest of the instrument can be invoked by the common command

*TST

If it is important to know whether the last command is completed, then send the common command

*OPC?

Condition Register

A condition register contains the current status of the hardware and firmware. It is continuously updated and is not latched or buffered. You can only read condition registers. If there is no command to read the condition register of a particular status group, then it is simply invisible to you.

Transition Filters

Transition filters are used to detect changes of state in the condition register and set the corresponding bit in the event register. You can set transition filter bits to detect positive transitions (PTR), negative transitions (NTR) or both. Transition filters are therefore read/write registers. They are unaffected by *CLS.

Event Register

An event register latches transition events from the condition register as specified by the transition filters or records status events. Querying (reading) the event register clears it, as does the *CLS command. There is no buffering, so while a bit is set, subsequent transition events are not recorded. Event registers are read only.

20

General Programming Aspects

Status Model

Enable Register

The enable register defines which bits in an event register are included in the logical OR into the summary bit. The enable register is logically ANDed with the event register and the resulting bits ORed into the summary bit. Enable registers are read/write, and are not affected by *CLS or querying.

Although all status groups have all of these registers, not all status groups actually use all of the registers. The following table summarizes the registers used in the instrument status groups.

Status Byte

The status byte summarizes the information from all other status groups. The summary bit for the status byte actually appears in bit 6 (RQS) of the status byte. When RQS is set it generates an SRQ interrupt to the controller indicating that at least one instrument on the bus requires attention. You can read the status byte using a serial poll or *STB?
