Page 12: Instrument Compatibility
GENERAL GPIB IEEE-488 INTERFACE INFORMATION BUS DESCRIPTION Most instruments in the MG3690B series are compatible with SCPI INSTRUMENT programming commands; however, some early production instruments COMPATIBILITY offered SCPI programmability as a special option SM5821. SCPI pro- grammability became standard starting with instrument serial num- ber 082001.
Page 13 GENERAL GPIB IEEE-488 INTERFACE INFORMATION BUS DESCRIPTION The devices on the GPIB are connected in parallel, as shown in Fig- ure 1-1. The interface consists of 16 signal lines and 8 ground lines in a shielded cable. Eight of the signal lines are the data lines, DIO 1 thru DIO 8.

Page 19: Message Types
GENERAL GPIB IEEE-488 INTERFACE INFORMATION BUS DESCRIPTION There are three types of information transmitted Message Types over the GPIB—interface function messages, device-specific commands, and data and instrument status messages. Interface Function Messages The controller manages the flow of information on the GPIB using interface function messages, usually called commands or command messages.
Page 20 GENERAL GPIB MG369XB INFORMATION GPIB OPERATION In some cases data messages will be transmitted from the external controller to the device. For exam- ple, messages to load calibration data. An SRQ (service request) is an interface function message sent from the device to the external control- ler to request service from the controller, usually due to some predetermined status condition or error.

Chapter 4 Error Messages This chapter lists and describes each of the error messages related to INTRODUCTION MG369XB signal generator operation. In addition, it provides informa- tion about the error message elements, the error query command, the error queue, and the classes of error messages. The :SYSTem:ERRor? query command is a request for the next entry ERROR QUERY in the instrument’s error queue.
Page 198: Error Queue
ERROR MESSAGES ERROR QUEUE As errors are detected, error messages are placed in a queue. This ERROR QUEUE queue is first in, first out and can hold a maximum of 10 messages. If the queue overflows, the last error message in the queue is replaced with the error message –350, “Queue overflow”...
Page 199: Command Errors
ERROR COMMAND MESSAGES ERRORS An <error code> in the range [–199, –100] indicates that an IEEE COMMAND ERRORS 488.2 syntax error has been detected by the instrument’s parser. The occurrence of any error in this class should cause the command error bit (bit 5) in the standard event status register to be set.
Page 200 ERROR COMMAND MESSAGES ERRORS –109 “Missing parameter” Fewer parameters were received than required for the header; for example, the *SAV common com- mand requires one parameter, so receiving *SAV is not allowed. –110 “Command Header Error” An error was detected in the header. This error mes- sage should be used when the device cannot detect the more specific errors described for errors –111 through –119.
Page 201 ERROR COMMAND MESSAGES ERRORS –124 “Too many digits” The mantissa of a decimal numeric data element contained more than 255 digits excluding leading zeros (see IEEE 488.2, 7.7.2.4.1). –128 “Numeric data not allowed” A legal numeric data element was received, but the device does not accept one in this position for the header.
Page 202 ERROR COMMAND MESSAGES ERRORS –150 “String data error” This error, as well as errors –151 through –159, are generated when parsing a string data element. This particular error message should be used if the de- vice cannot detect a more specific error. –151 “Invalid string data”...
Page 203: Command Errors
ERROR COMMAND MESSAGES ERRORS –180 “Macro error” This error, as well as errors –181 through –189, are generated when defining a macro or executing a macro. This particular error message should be used if the device cannot detect a more specific error. –181 “Invalid outside macro definition”...
Page 204: Execution Errors
ERROR EXECUTION MESSAGES ERRORS An <error code> in the range [–299,–200] indicates that an error has EXECUTION ERRORS been detected by the instrument’s execution control block. The occur- rence of any error in this class should cause the execution error bit (bit 4) of the standard event status register to be set.
Page 205 ERROR EXECUTION MESSAGES ERRORS –211 “Trigger Ignored” Indicates that a GET, *TRG, or triggering signal was received and recognized by the device but was ig- nored because of device timing considerations; for example, the device was not ready to respond. Note: a DTO device always ignores GET and treats *TRG as a command error.
Page 206 ERROR EXECUTION MESSAGES ERRORS –223 “Too much data” Indicates that a legal program data element of block, expression, or string type was received that contained more data than the device could handle due to memory or related device-specific require- ments. –224 “Illegal parameter value”...
Page 207 ERROR EXECUTION MESSAGES ERRORS –252 “Missing media” Indicates that a legal program command or query could not be executed because of missing media; for example, no disk. Definition of what constitutes missing media is device-specific. –253 “Corrupt media” Indicates that a legal program command or query could not be executed because of corrupt media;...
Page 208 ERROR EXECUTION MESSAGES ERRORS –260 “Expression error” Indicates that an expression program data element related error occurred. This error message should be used when the device cannot detect the more spe- cific errors described for errors –261 through –269. –261 “Math error in expression”...
Page 209 ERROR EXECUTION MESSAGES ERRORS –276 “Macro recursion error” Indicates that a syntactically legal macro program data sequence could not be executed because the de- vice found it to be recursive (see IEEE 488.2, 10.7.6.6). –277 “Macro redefinition not allowed” Indicates that a syntactically legal macro label in the *DMC command could not be executed because the macro label was already defined (see IEEE 488.2, 10.7.6.4).
Page 210: Device-Specific Errors
ERROR DEVICE-SPECIFIC MESSAGES ERRORS An <error code> in the range [–399,–300] or [1, 32767] indicates that DEVICE-SPECIFIC the instrument has detected an error which is not a command error, a ERRORS query error, or an execution error; some device operations did not prop- erly complete, possibly due to an abnormal hardware or firmware con- dition.
Page 211 ERROR DEVICE-SPECIFIC MESSAGES ERRORS –315 “Configuration memory lost” Indicates that nonvolatile configuration data saved by the device has been lost. The meaning of this er- ror is device-specific. –330 “Self-test failed” –350 “Queue overflow” A specific code entered into the queue in lieu of the code that caused the error.
Page 212: Query Errors
ERROR QUERY MESSAGES ERRORS An <error code> in the range [–499,–400] indicates that the output QUERY ERRORS queue control of the instrument has detected a problem with the mes- sage exchange protocol described in IEEE 488.2, Chapter 6. The occur- rence of any error in this class should cause the query error bit (bit 2) in the standard event status register to be set.
Page 213: Parser Errors
ERROR PARSER MESSAGES ERRORS 4-10 An <error code> in the range [201, 212] is generated by the instru- PARSER ERRORS ment’s parser in response to the error condition described.
