4、 be programmed with caution to prevent hazardous voltages from being produced without sufficient warning to the operator. 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 prog

5、rams. 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 a

6、n 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!

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, ,

14、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 wil

15、l 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 FunctionASCIICont

17、A 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

18、) 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.

21、VISCB00 RQS Requesting Service. 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 rea

22、d 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

23、 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

24、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

30、 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, ex
