Chapter 5 Error MessagesCalibration Errors770 Nonvolatile arb waveform memory checksum failure771 Nonvolatile cal memory checksum failure772 Nonvolatile system memory checksum failure773 Nonvolatile state memory checksum failure774 Nonvolatile memory erase failure775 Nonvolatile memory write failure780 to 788 See “Arbitrary Waveform Errors” on page 240.800 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 previous specified as a storage location.850 Cal setup invalid5851 Negative offset gain cal required (CAL:SETup 50)852 Flatness DAC gain cal required (CAL:SETup 64)853 AM cal 1 required (CAL:SETup 30)854 AM cal 2 required (CAL:SETup 31)855 Cal load resistance not specified (CAL:SETup 33)856 Square wave positive offset cal required (CAL:SETup 60)857 Square wave 50% duty cycle cal required (CAL:SETup 62)858 AM cal 3 required (CAL:SETup 32)239
