A legal character data element was encountered -148 Character data not allowed where prohibited by the device.
  • Page 79 REMOTE CONTROL Execution Errors Overview An <error/event number> in the range [ -299 , - 200 ] indicates that an error has been detected by the instrument’s execution control block. The occurrence of any error in this class shall cause the execution error bit (bit 4) in the event status register (IEEE 488.2, section 11.5.1) to be set.

Error Code Description Indicates that some error, termed “system -310 System error error” by the device, has occurred. This code is device-dependent. Indicates that the firmware detected a fault -320 Storage fault when using data storage.
