Chapter 5 Error MessagesExecution Errors501 Isolator UART framing error502 Isolator UART overrun error511 RS-232 framing error512 RS-232 overrun error513 RS-232 parity error514 Command allowed only with RS-232The following three commands are used only with RS-232:SYSTem:LOCal, SYSTem:REMote, and SYSTem:RWLock.521 Input buffer overflow522 Output buffer overflow550 Command not allowed in localYou should always execute the SYSTem:REMote command beforesending other commands over the RS-232 interface. This error is alsogenerated if you attempt to execute the DISP:TEXT command while inthe local mode (this command is allowed in remote only).580 Phase-locked loop is unlockedOption 001 Phase-Lock Only. The function generator has detected an“unlock” condition. You must execute the PHAS:UNL:ERR:STAT ONcommand to enable this error.800 Block length must be evenThe function generator represents binary data for arbitrary waveformsas a 12-bit integers, which is sent as two bytes (DATA:DAC VOLATILEcommand only). An odd number of bytes is not accepted because thefunction generator would not know how to interpret the last single byte.810 State has not been storedThe memory location specified in the *RCL command was not used in aprevious *SAV command. You cannot recall the instrument state from amemory location that was not previously specified as a storage location.236
