Programs should be written carefully and tested extensively to ensure safe operation of the 5500A Calibrator. Fluke suggests that you include error catching routines in your programs. These error catching routines will assist in detecting programming errors that could result in the instrument behaving differently to your intention. By setting the Service Request Enable (SRQ) register, described in paragraph 5-60, the 5500A Calibrator can be programmed to cause an SRQ when an error is detected. The following program example shows a skeleton program including error catching: 10PRINT 4, “*CLS”! Clear status 20PRINT 4, “*SRE 8”! Set SRE Error Avail. 30ON SRQ GOTO 1000! Enable SRQ Function 100!

Request fault text 1040 INPUT 4, A$! Input fault text 1050 PRINT “Fault ”;A$“ detected” ! Print message 1060 PRINT 4, “STBY”! Place 5500A in standby 1070 STOP 3 TYPES OF COMMANDS Device-Dependent Commands Commands unique to 5500A. Common Commands Commands defined by the IEEE 488.2 standard. Query Commands Commands ending with an ?. Compound Commands Two or more commands in a single command line. Coupled Commands Commands that could interfere with each other. Overlapped Commands Commands requiring more time to execute. Sequential Commands Commands that execute immediately.

Separate parameters with commas. 2. Numeric parameters up to 15 significant digits and exponents in the range +/-1.0E+/-20. 3. Null parameters cause an error, e.g., the adjacent commas in OUT 1V, ,2A. 4. Expressions, for example 4+2*13, are not allowed as parameters. 5. Binary Block Data can be in one of two IEEE 488.2 formats: Indefinite Length Format Accepts data bytes after #0 until the ASCII Line Feed character is received with an EOI signal (for RS-232, a line feed or carriage return will terminate the block). Definite Length Format The non-zero digit specifies the number of characters that will follow in the field. Extra Space or Tab Characters One space after a command is required. You can insert extra spaces or tabs as desired. Terminators Terminator Characters FunctionASCIIControlC Code #Code Carriage Return 13Chr(13) Mn Line Feed10Chr(10) Jr Backspace8Chr(8) Hb Form Feed12Chr(12) Lf 6 COMMAND SYNTAX (cont) IEEE-488 Interface The 5500A sends the ASCII character Line Feed with the EOI control line held high as the terminator for response messages. RS-232 Interface The 5500A Calibrator returns an EOL (End of Line) character with each response, selectable as CR, LF or both CRLF. Incoming Character Processing 1. The most significant data bit (DIO8) is ignored. 2. All data is taken as 7-bit ASCII. 3. Lower-or upper-case characters. 4. ASCII characters less than 32 (Space) are discarded, except for characters 10 (LF) and 13 (CR) and in the *PUD command argument. Response Message Syntax Response Data Types DATA TYPEDESCRIPTION IntegerDecimal numbers to 32768. FloatingNumbers plus an exponent. StringASCII characters within double quotes (“string”).

Set to 1 whenever bits ESB, MAV, EAV, or ISCB change from 0 to 1 and are enabled (1) in the SRE. When RQS is 1, asserts the SRQ control line. MSS Master Summary Status. Set to 1 whenever bits ESB, MAV, EAV, or ISCB are 1 and enabled (1) in the SRE. This bit can be read using the *STB? command in serial remote. ESBEvent Status. Set to 1 when one or more enabled ESR bits are 1. MAV Message Available. The MAV bit is set to 1 whenever data is available in the 5500As IEEE-488 interface output buffer. EAVError Available. An error has occurred and an error is available to be read from the error queue by using the ERR? query. ISCB One or more enabled ISCR bits are 1. For RS-232, transmitting the P character (hold down the key and press P) returns the SPLSTR (Serial Poll String) and the status byte. Service Request (SRQ) Line IEEE-488 Bus control line that asserts to notify the controller that it requires some type of service. RS-232 Sends the SRQSTR string over the serial interface when the SRQ line is set. Service Request Enable Register (SRE) The SRE enables or masks the bits of the Serial Poll Status Byte. The SRE is cleared at power up. 9 CHECKING 5500A STATUS (cont) ESR and ESE 15141312111098 00000000 76543210 PON0CMEEXEDDEQYE0OPC PON Power on. Line power has been turned off and on. CME Command error. An incorrectly formed command has occurred. EXEExecution error. An error occurred while the 5500A tried to execute the last command. DDEDevice-dependent error. An error related to a device-dependent command has occurred. QYEQuery error. No response data was available or appropriate. OPC Operation complete. All commands previous to *OPC command have been executed. 10 CHECKING 5500A STATUS (cont) ISR, ISCE, and ISCR 15141312111098 00RPTBUSY SETTLED REMOTE0UUTBFUL UUTDATA 76543210 HIVOLT MAGCHG TMPCAL0IBOOSTVBOOST0OPER RPTBUSYSet to 1 when a calibration report is being printed to the serial port.

OPERSet to 1 when the 5500A is in operate; 0 to when it is in standby. 11 Output Queue The output queue is loaded whenever a query is processed, and holds up to 800 characters. If the queue is empty, the 5500A Calibrator does not respond to the INPUT statement. The Message Available (MAV) bit in the Serial Poll Status Byte is 1 if there is something in the output queue and 0 if the output queue is empty. Error Queue When a command error, execution error, or device-dependent error occurs, its error code is placed in the error queue where it can be read by the ERR? command. The error queue contains up to 16 entries. 12 COMMAND SUMMARY Error Mode Commands EDITSets edit field. EDIT?Returns edit field setting. INCRIncrements or decrements output.
