5.17 DEMAG MODE

DEMAG MODE is used for demagnetizing coils. Enter values for Frequency and Start

Level, then press the Start soft key. First the coil is saturated by applying the set Frequency at the Start Level. The coil is then demagnetized by slowly reducing the level to zero.

5.17.1 DEMAG MODE Parameters

Frequency

Start Level

Set by highlighting the parameter with the and navigation keys, then altering the setting in pre-determined steps with the and navigation keys, or by finer increments using the data entry keypad. The range is:

20Hz to 3MHz

Set by highlighting the parameter with the and navigation keys, then altering the setting in pre-determined steps with the and navigation keys, or by using the data entry keypad. The range is:

1mV to 10V

At frequencies above 300kHz the maximum start level is restricted.

Advanced Operation

Figure 5-53 The SETTINGS Page

There are eight parameters which may be altered from within the settings page: GPIB address,

Freq steps, Connection, Measurement, Test Conditions, Ratio Correction,

Demagnetisation, Low Magnetisation.

5.18.1 The SETTINGS Page Parameters

GPIB Address

Freq Steps

The analyzer’s default GPIB address is 6. This may be changed by highlighting the GPIB address parameter with the and navigation keys, then altering the address with the or navigation keys or the data entry keypad. Allowable addresses are

0 to 30 inclusive.

This sets the frequency steps used when the measurement frequency is altered using the navigation keys. Two options are available: Coarse or Fine. Set by highlighting the Freq steps parameter with the and navigation keys, then using the or

navigation keys to toggle between the two choices. With Coarse steps selected, the frequency steps are 33% or less; with Fine steps selected, the frequency steps are 1% or less.

Even with Coarse frequency steps selected, the data entry keypad can be used to set the measurement frequency with the maximum possible resolution and accuracy.

Connection

Measurement

Test Conditions

Ratio Correction


Toggles the analyzer between 2- and 4-terminal operation by highlighting the Connection parameter with the and navigation keys, then using the or navigation keys to toggle between the two choices.

Alternatively, the 2/4 Term control key can be used to switch between 2- and 4-terminal operation (see section 4.2.5).

Note:

1) When 2-terminal measurement is selected the 2/4 term control key indicator will light and the display will show 2-TERM

…MODE at the top of the screen.

2) The leads will require retrimming when switching from 4- to

2-terminal measurement or vice versa.

Toggles the analyzer between Single shot mode and Repetitive

mode operation. Set by highlighting the Measurement parameter with the and navigation keys, then using the or navigation keys to toggle between the two choices.

Alternatively, the Sngl/Rep control key can be used to select either single shot or repetitive mode (see section 4.2.5).

Toggles the analyzer between Global and Non-global test conditions. With Global set, any parameter, e.g. drive level, frequency, set in one mode of operation, is automatically reflected in all other modes. For example if the IMPEDANCE MODE frequency is set to 300Hz, the TRANSFORMER MODE frequency will automatically be changed to 300Hz too. With Non-

global set, the parameters in each mode may be set independently of the parameters in all other modes. Set by highlighting the Test

Conditions parameter with the and navigation keys, then using the or navigation keys to toggle between the two choices.

Sets the ratio correction to Off, Normal transformer or Auto

transformer during transformer ratio measurements. Set by highlighting the Ratio Correction parameter with the and navigation keys, then using the or navigation keys to select the setting required.

When measuring the turns ratio of transformers with a floating secondary winding, the ratio correction should be set to Normal

transformer or Off. If the primary impedance is low, it is highly recommended to turn ratio correction Off. When measuring the turns ratio of auto transformers (transformers with a common connection between one end of the primary and secondary windings) the ratio correction should be set to Auto transformer.

5–52

Demagnetisation

Low Magnetisation

Advanced Operation

This is a global setting. With Demagnetisation set On, components measured using AC primary settings, i.e. L, Q, C, D,

Z, R, in IMPEDANCE MODE and L+Q (Pri) in

TRANSFORMER MODE, will be demagnetized, using the settings in DEMAG MODE, before the component measurement is performed. The demagnetization function will only occur when measurements are performed in single-shot mode. When the analyzer is set to make repetitive measurements, the

Demagnetisation function is disabled.

Sometimes, when connecting a component to the measurement terminals, the connection coincides with a signal peak from the analyzer which may saturate the component. This situation can be avoided by setting Low Magnetisation On. This global setting shorts the analyzer’s terminals while the component is connected to the measurement leads/fixture. When a single-shot measurement is performed, by pressing the Trigger key, the short is removed and the measurement made. When the measurement has been made, the short is reapplied to the analyzer terminals, allowing removal of the component without the risk of saturation at this point. When the analyzer is set to make repetitive measurements, the Low Magnetisation function is disabled

5.19 The CAL STATUS Page

The CAL STATUS page, shown in Figure 5-54, is displayed by pressing the CAL STATUS soft key from the MAIN MENU.

In the Calibration status area, indicates that the named calibration has been performed and is valid. indicates that the named calibration has not been performed or is not valid.

The Trim status area shows the trims that have been performed and which conditions were used for trimming. The Trim column lists the possible trims. The Freq column displays No

trim, Spot trim or All freq to show the kind of trim performed. The Spot column shows None of no trim has been performed. If a spot trim is performed, the Spot column shows the frequency the spot trim was performed at. If the trim was performed with the All freq setting, the Spot column shown the frequency set in IMPEDANCE MODE when the trim was performed; the analyzer trims at this frequency, in addition to the normal trim frequencies, when an All freq trim is performed. The Connect column shows 4-term or 2-term, depending on whether the trim was performed in 2- or 4-terminal mode.

6. GENERAL PURPOSE INTERFACE BUS (GPIB)

6.1 GPIB Control

6.1.1 Introduction

The GPIB is a parallel port designed to be used for communication between instruments

(listeners) and control devices (talkers) such as PCs fitted with a suitable interface card. The interface protocol is defined by the IEEE488.1 standard. Some additional generic capabilities of the listeners and talkers are defined by IEEE488.2. The SCPI standard defines the highest level of command structure including a number of standard commands for all instruments.

6.1.2 Interface Specification

The IEEE 488.1 bus standard and the IEEE 488.2 code standard are fully supported. The command set has also been designed to the SCPI standard.

General Purpose Interface Bus (GPIB)

6.1.3 Changing GPIB Address

Each instrument on the GPIB requires a unique address, this can be set to any address in the range 0 to 30.

The default address is 6. This may be changed from the SETTINGS page, as follows:

1) From the MAIN MENU select SETTINGS.

2) Highlight the settings page GPIB address parameter with the and navigation keys.

3) Alter the address with the or navigation keys or the data entry keypad.

The GPIB address is stored in non-volatile memory.

6.1.4 Message Syntax

A GPIB message is made up of one or more commands. Commands can be separated into two groups, common commands and subsystem commands. The available common commands are defined by IEEE488.2 and are primarily concerned with the instrument’s GPIB configuration, e.g. reading error registers and identifying the instrument. The subsystem commands are the higher level commands that follow the SCPI guidelines and are concerned with setting up the instrument functions, e.g. changing the frequency and drive level.

6.1.4.1 Message structure

Messages are sent to the instrument as ASCII character strings. The structure of these strings can be seen in Figure 6-1. When interpreting the strings the instrument is not case-sensitive.

Figure 6-1 GPIB Message Structure

The path command prefix allows access to commands in the SCPI command tree. Using this approach greatly simplifies GPIB programming by allowing related commands to be grouped together. The next part of the string is the command itself which has the structure shown in

Figure 6-2. Multiple commands can be sent in one message by separating them with a semicolon (maximum length 256 bytes). The terminator indicates the end of the command string to the instrument: this can be the sending of the line-feed character (ASCII 0Ah) and/or the assertion of the EOI handshake line on the GPIB bus.


Figure 6-2 GPIB Command Structure

Each instrument command begins with a mnemonic that describes the required action, e.g.

FREQ

for changing the frequency.

If the command requires a parameter, then the next character should be a white space character

(ASCII 20h), although any character in the range 00h-20h can be used with the exception of line-feed (ASCII 0Ah).

The parameter itself can take one of three forms depending on the command:

1) Discrete data

This includes words like ON, OFF and ABS.

2) Real Number

A floating point number that can be in engineering format or a number with a multiplier suffix K (kilo-), M (mega-) or G (giga-).

For example:

FREQ 1000.0

FREQ 1E+3

FREQ 0.1E4

FREQ 1k are all valid ways of setting a frequency of 1kHz.

3) Integer

A single integer number. Often used to indicate a Boolean state.

For example:

RANGE 1 will select range 1.

If invalid data is supplied then a command error will be generated. If data is supplied but the instrument is not able to apply the setting, an execution error will be generated. If the instrument is unable to exactly comply with the command and can only apply the nearest available, a device specific error is generated. Details of these error codes can be found in

Figure 6-6.

6.1.4.2 Hierarchical Commands

As described in the previous section, SCPI uses a command tree to simplify device programming. This structure is similar to the directory structure used on most computers. To

6–4

General Purpose Interface Bus (GPIB) access a specific command in a specific mode the user must supply the ‘path’ to reach that particular command within the tree.

When the unit is powered up the initial path is ‘root’ which is the top level from which all paths must start.

Note that common commands (which by convention always start with the ‘*’ character) are not part of the tree and can be accessed regardless of the current path.

So to select the impedance measurement function in deviation mode, the path must describe the command tree as below:

The ‘:’ character is used as the path separator so the command string will be:

:DEV:FUNC:Z

Note that the string starts with ‘:’. This tells the instrument to start from the ‘root’ path.

Whenever a terminator is reached (line-feed and/or EOI) the path is reset to the root path, so each new GPIB command string must state the full path in order to work correctly, for example:

To set a measurement frequency of 1kHz at a level of 1.0V, the following string can be used:

:IMP:FREQ 1k;LEV 1.0V <line-feed>

Or it can be expressed as two separate commands:

:IMP:FREQ 1k <line-feed>

:IMP:LEV 1.0 <line-feed>

However, the following will not work as the second command will be run from the ‘root’ path, not the measurement path which was required:

LEV 1.0 <line-feed>


Summary: The following are the rules for negotiating the command hierarchy

• On power-up or reset, the current path is set to the root.

• Message terminator, line-feed (ASCII 0Ah) or EOI, sets the current path to the root.

• When a colon is the first character of a command, it specifies that the next command mnemonic is a root level command.

• When a colon is placed between two path mnemonics, the current path is moved down one level in the command tree if the path name is valid.

• A semicolon separates two commands in the same message without changing the current path.

• If a command requires more than one parameter, the separate adjacent parameters must be specified using a comma. Commas do not affect the current path.

• Common commands, such as *RST, *RCL, are not part of the tree. An instrument interprets them in the same way, regardless of the current path setting.

Other syntax rules

• Commands will be executed in the order in which they appear in the string.

• A command string can contain any number of ‘query commands’: the response will contain the replies to each query separated by a semicolon.

• Only commands available in the selected mode will be accepted. Otherwise, an Execution

Error will be generated. For example, AC frequency cannot be set if Rdc type of test is selected

• Either full or abbreviated forms of the device specific commands will be accepted. The abbreviated form is indicated by upper case letters in section 6.2.

• Device specific commands have the same effect as pressing the equivalent front panel key and can be expected to interact with any other instrument settings in the same way.

6.1.5 Data Output

6.1.5.1 Output Syntax

For each query which generates an output response, a Response Message Unit (RMU), will be generated. This consists of a string of numbers or alphanumeric characters; if more than one

RMU is generated they will be delimited with a semicolon. The terminator, line-feed and EOI asserted indicates the end of data output. All characters will be upper case.

Figure 6-3 GPIB Data Output

6–6


Figure 6-4 GPIB RMU Structure

6.1.5.2 Multiple Items

Some commands will generate an RMU containing more than one item of data (e.g. TRIG will generate a first and second result). In this case, each item of response data will be separated by a comma. Note that the maximum number of characters that can be output is 256, any data beyond this will be lost.

If the command string contained multiple queries then the response will contain multiple

RMUs, each of which will be separated by a semicolon.

6.1.5.3 Numeric Format

The format of numeric results will correspond to that used for the instrument display, with the engineering multiplier (if any) replaced by an equivalent 10’s exponent. If the FAST-GPIB mode is being used then numbers will be output in a raw engineering format.

6.1.6 Status Reporting

6.1.6.1 Status byte

The status byte is used to summarize information from the other status groups. It is shown in

Figure 6-5, which conforms to IEEE 488.2 and SCPI. The status byte can be read by the query command *STB? or by performing a serial poll on the instrument (these two are identical although the point at which the RQS bit can be cleared is slightly different).

BIT Meaning True = ‘1’

7

Operation Status Event Register summary bit. This bit is true when measurement or trimming etc., is in progress

RQS – ReQuest for Service. When the bit in the Service Request Enable mask is set with the corresponding bit in the status register true, this will trigger a service request to the controller.

MSS – Master Summary Status bit. The version of the request for service bit which appears in the Status Byte.

ESB – Event Summary Bit. When unmasked by the ESE register, this bit will be set whenever the corresponding bit or bits are set in the Event Status

Register.


BIT

4

2

Meaning True = ‘1’

MAV – Message available. The output queue has data to be read.

A summary bit from Questionable Data. This bit is not used, so is always 0.

This is a summary bit of error and instrument status messages. True if any new status information is available.

6–7

Figure 6-5 Status Byte Register

6.1.6.2 Service Request Enable Register

The service request enable register (SRE) is a mask determining the conditions in which the

SBR will generate a service request. It is bit-wise ANDed with the SBR and if the result is not zero then bit 6 of the SBR is set (see Figure 6-5). The SRE is set by the *SRE command and read by the *SRE? command.

6–8


6.1.6.3 Standard Event Status Register

The standard event status register (ESR) contains the 8 bits of the operation status report which is defined in IEEE 488.2. If one or more event status bit is set to ‘1’ and their enable bits are also ‘1’, bit 5 (called ESB) of the status register byte is set to ‘1’.

Each bit of the standard event status register is shown below.

BIT Name Meaning (True = ‘1’)

7 Power On (PON)

6 User Request (URQ)

True when the instrument power supply has been turned OFF and then ON since the last time this register was read.

Not used. Always 0.

5

4

Command Error (CME)

Execution Error (EXE)

True if the following command errors occur:

An IEEE 488.2 syntax error occurred.

The device received a Group Execute Trigger (GET) inside a program message.

True when a parameter following a header of a GPIB command was evaluated by the instrument as being outside of its legal input range or is otherwise inconsistent with the instrument’s capabilities.

True when any bit is set in the Encoded Message Register. 3 Device Dependent Error

(DDE)

2 Query Error (QYE) True when attempting to read data from the output buffer in which no data was present, or when the data was lost.

1 Request Control (RQC) Not used. Always 0.

0 Operation Complete (OPC) True when the instrument has completed all selected pending operations before sending the *OPC command

Figure 6-6 Standard Event Status Register


Figure 6-7 Event Status Byte Register

6.1.6.4 Event Status Enable Register

The event status enable register (ESE) is a mask determining the conditions in which the ESR will set bit 5 of the SBR. It is bit-wise ANDed with the ESR and if the result is not zero then

ESB (bit 5) of the SBR is set (see Figure 6-7). Thus any event affecting the ESR can be made to generate a Service Request in conjunction with the ERE and the SRE.

The event status enable is set by the *ESE command and read by the *ESE? command.

6–10


Figure 6-8 Standard Operation Status Group

6.1.6.5 Standard Operation Status Group

The standard operation status group provides information about the state of the measurement systems in the instrument. This status group is accessed through the STATus subsystem.

Standard operation status includes a condition register, event register, and an enable register.

Figure 6-8 illustrates the structure of standard operation status.

6.1.6.6 Standard Operation Status Condition Register

This is a 16-bit register gathering information about the state of the measurement systems in an instrument. According to SCPI recommendation, we define:

BIT Meaning (True = ‘1’)

0 Calibrating bit which is true when S/C trimming, O/C trimming, or calibrating is in progress, and otherwise reset.

4 Measuring bit which is true when measurement is in progress, and otherwise reset.

Other bits are unused and are 0.


6.1.6.7 Standard Operation Status Event Register

This is a 16-bit register; each event bit in the event register corresponds to a condition bit in the standard operation status condition register. According to SCPI recommendation, we define:

BIT Meaning (True = ‘1’)

0 True when S/C trimming, O/C trimming, or calibration measurement is completed.

4 Set true when single shot measurement is completed.

Other bits are uncommitted and are always 0.

6.1.6.8 Encoded Message Register

All front panel warnings and messages can be monitored over the GPIB. There are also several extra flags, otherwise hidden, that are of interest to the bus user.

The encoded message query command returns a string of 8 hexadecimal digits. Each digit represents 4 different errors or their combinations.

The encoded message format is as follows:

D7 D6 D5 D4 D3 D2 D1 D0

D0 indicates range or trim errors bit0 = Range Error bit1 = S/C Trim Error bit2 = O/C Trim Error bit3 = Calibrate Error

D1 is reserved for future expansion.

D2 indicates errors related to ALC operations. bit0 = CANNOT SET LEVEL bit1 = Reserved bit2 = ALC HELD bit3 = Reserved

D3 indicates errors related to data entry. bit0 = Nearest Available

6–12

General Purpose Interface Bus (GPIB) bit1 = Units Mismatched bit2 = Connection Error bit3 = Reserved

D4 is reserved.

D5 represents errors related to voltage Bias. bit0 = Bias overload, Bias Turned Off bit1 = Reserved bit2 = Reserved bit3 = Reserved

D6 is reserved.

D7 is reserved.

Any of the above messages will set bit 2 of the Service Request Register. If ‘Range Error’ or

‘Connection Error’ occurs, pseudo-measurement results ‘999.9E+15, 999.9E+15’ or

‘999.9E+15’ will be produced dependent on the measurement function.

6.2 Device-Specific Commands

The sub-system commands are grouped in different modes similar to the local operation. The recommended discipline to control the instrument under GPIB is to select the mode and the type of test first, then change the measurement conditions. Trying to change measurement conditions which are not in the present mode and type of test will be rejected and return an error flag.
