Safety Information

Safety

This is a Safety Class 1 instrument (provided with terminal for protective earthing). Before applying power, verify that the correct safety precautions are taken (see the following warnings). In addition, note the external markings on the instrument that are described under Safety Symbols. Do not operate the instrument with its covers removed. Replace fuse only with specified type.

Warning

Before turning on the instrument, you must connect the protective earth terminal of the instrument to the protective earth conductor of the (mains) power cord. The mains plug must only be inserted in a socket outlet with a protective earth contact. Do not negate the protective action by using an extension power cord without a protective grounding conductor. Grounding one conductor of a two-conductor outlet is not sufficient protection.

Service instructions are for trained service personnel. To avoid dangerous electric shock, do not perform any service unless qualified to do so. Do not attempt internal service or adjustment unless another person, capable of rendering first aid and resuscitation, is present.

If you energize this instrument using an auto-transformer (for voltage reduction), make sure that the common terminal is connected to the earth terminal of the power source.

Whenever it is likely that the ground protection is impaired, you must make the instrument inoperative and secure it against any unintended operation.

Do not operate the instrument in the presence of flammable gases or fumes. Operation of any electrical instrument in such an environment constitutes a definite safety hazard.

Do not install substitute parts or perform any unauthorized modification to the instrument.

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 81110A. 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.

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 double pulse delay is:

:PULS:DOUB: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.: enable double pulse mode by [SOURce]:PULSe:DOUBle[1|2][:STATe] ON|OFF. Sufficient to use:

:PULS:DOUB ON # enables double pulse mode for

# output 1



The commands to set the timing and level parameters, except of period/frequency, have to be specified for output 1 and output 2. If there is no output specified the command will set the default output

1. So, for setting a high level of 3 Volts for output 1 and output 2 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

:VOLT2:HIGH 3V # sets high level of 3 V at out 2

General Programming Aspects

PPPPrrrrooooggggrrrraaaammmmmmmmiiiinnnng

 It is recommended to test the new setting which will be programmed

on the instrument by setting it up manually. Enable the outputs so that the instruments 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, :OUTPut1 ON) as the last command. With this procedure it is possible to switch off the error check system (:SYSTem:CHE Ck OFF) to increase programming speed. The error check is enabled again by sending *RST.

*RST # set default settings :DISP OFF # switch off display update :SYST:CHEC OFF # switch off error check ... # other commands to set modes ... # and parameters :OUTP1 ON # enable the output 1

 Selftest of the instrument can be invoked by the common command

*TST

 The Agilent 81110A offers auto calibration for the period (VFO), delay

and width circuitry by the device command :CALibration. It is recommended to query whether the calibration is passed by sending :CALibration?.

Each status group is made up of component registers, as shown in the figure below.

Transition Filters

1 0

PTR NTR

Event Register

Latched

Enable Register

Summary Bit

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.

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

or querying.

*CLS

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?

You program the comprehensive triggering capabilities of the instrument using the SCPI :ARM and :TRIGger subsystems. Using these two command subsystems you can program the operating modes of the instrument which are set up using the MODE/TRG screen on the frontpanel.

Use the :ARM subsystem to select the overall triggering mode of the instrument (CONTINUOUS,TRIGGERED,GATED,EXT WIDTH), and the :TRIGger subsystem to select the pulse-period source, triggering and number of pulse periods per :ARM event (BURST

PATTERN length).

This command disables the arming/triggering system. The arming/ triggering system is re-enabled by switching off the External Width mode.

Pulses

Set Pulses mode by setting the trigger count to 1 so that a single triggered pulse period is generated for every arm event. The trigger source sets the pulse period:

The instrument uses each byte of data set one Bit in the pattern memory. If you don't specify a particular channel, the lowest three bits of each byte are used to set all three channels, and the top five bits are ignored. Note that you can therefore use the ASCII characters 0,1,2 and 3, to program Outputs 1 and 2 in binary with STROBE=0 (or 4,5,6, and 7 for STROBE=1):

This command tree accesses the questionable status group. The questionable status group contains warning bits for voltage, current, time and frequency parameters. A warning occurs when the output signal could be out of specification due to the combined specification uncertainties of many parameters, although all parameters are set within their individually specified limits. If a parameter is set outside its specified limits an error is generated.

the instrument from entering remote mode by using the REN line of the GP-IB to maintain local mode.
