LIMITED WARRANTY & LIMITATION OF LIABILITY Each Fluke product is warranted to be free from defects in material and workmanship under normal use and service. The warranty period is one year and begins on the date of shipment. Parts, product repairs and services are warranted for 90 days. [. . . ] IEEE-488 Interface Messages (Send) Mnemonic END Name End Function A message that occurs when the 5500A asserts the EOI control line. The 5500A asserts EOI while it transmits the ASCII character LF for its termination sequence or terminator. A control line that any device on the bus can assert to indicate that it requires attention. Refer to "Checking 5500A Status" for details. The status byte is what the 5500A sends when it responds to a serial poll (interface message SPE). DAC DAV RFD SRQ STB Data Accepted Data Valid Ready for Data Service Request Status Byte 5-29. Compound Commands A compound command is two or more commands in a single command line. For example, the following two commands could be entered individually, OUT 1 V, 60 Hz OPER where the 5500A Calibrator sources 1 V ac at 60 Hz, and then goes into operate, or they could be combined into a compound command, OUT 1 V, 60 HZ ; OPER using a semi-colon as a separator. Care must be taken when a compound command includes any of the coupled commands. (See "Coupled Commands. ") 5-30. Coupled Commands A coupled command refers to two or more commands that appear in a compound command (see "Compound Commands") that perform actions that could interfere with each other causing a fault. Commands in a compound command are separated by using the ; character. Compound commands using only coupled commands are not orderdependent. In Chapter 6, the command graphic shows a check mark for The five coupled commands are: CUR_POST DC_OFFSET HARMONIC OUT WAVE x Coupled commands. An example of coupled command interference is the command OUT 1 V ; RANGELCK ON followed by the command OUT 10 V ; RANGELCK OFF which can't be executed because RANGELCK ON in the first command locks the dc volts range, preventing the command OUT 10 V from executing. With a different order RANGELCK OFF ; OUT 10 V the second compound command can executed successfully. 5-28 Remote Operation Using Commands 5 5-31. Overlapped Commands Commands that begin execution but require slightly more time to complete are called overlapped commands, because they can be overlapped by the next command before they have completed execution. In Chapter 6, the command graphic shows a check mark for x Overlapped commands. The 25 overlapped commands are: BOOST CUR_POST DC_OFFSET DPF DUTY EARTH HARMONIC INCR LOWS MULT OPER OUT OUT_IMP PHASE RANGELCK *RST RTD_TYPE SCOPE SRC_PREF STBY TC_OFFSET TC_OTCD TC_REF TC_TYPE TRIG TSENS_TYPE WAVE ZCOMP You can use the command *WAI to wait until the overlapped command has completed execution before executing the next command. For example, OUT 1 V, 1 A, 60 HZ ; *WAI You can also use the status commands *OPC and *OPC?to detect completion of overlapped commands. (See "Checking 5500A Status. ") 5-32. Sequential Commands Commands that execute immediately are called sequential commands. In Chapter 6, the command graphic shows a check mark for x Sequential commands. The majority of the commands, 87 of 111 commands, are sequential. 5-33. Commands that Require the Calibration Switch to be Enabled The following commands do not work unless the rear panel CALIBRATION switch is in the ENABLE position: FORMAT ALL FORMAT CAL *PUD Attempting to use any of these commands with the CALIBRATION switch in the NORMAL position logs an error into the error queue. (Or it returns the error message if in the RS-232 Terminal Mode. ) 5-34.
