Arbitrary Waveform Errors

command only). An odd number of bytes is not accepted because the function generator would not know how to interpret the last single byte.

810State has not been stored

The memory location specified in the *RCL command was not used in a previous *SAV command. You cannot recall the instrument state from a memory location that was not previous specified as a storage location.

850Cal setup invalid

851Negative offset gain cal required (CAL:SETup 50)

852Flatness DAC gain cal required (CAL:SETup 64)

853AM cal 1 required (CAL:SETup 30)

854AM cal 2 required (CAL:SETup 31)

855Cal load resistance not specified (CAL:SETup 33)

856Square wave positive offset cal required (CAL:SETup 60)

857Square wave 50% duty cycle cal required (CAL:SETup 62)

The following errors indicate failures that may occur during an arbitrary waveform download. Refer to the Arbitrary Waveform Commands for more information specific to the use of arbitrary waveform commands. These commands are summarized on page <Reference> in the "Table of Contents by Function" for Chapter 3, SCPI Command Reference.

780 VOLATILE arb waveform has not been loaded

The DATA:COPY command copies the waveform downloaded into VOLATILE memory to the specified name. You must download the waveform using the DATA VOLATILE or DATA:DAC VOLATILE command prior to a copy operation.

781Not enough memory to store new arb waveform; use DATA:DELete Up to four user-defined waveforms can be stored in non-volatile memory. Use the DATA:DEL command to delete the waveform in VOLATILE memory or any of the four user-defined waveforms in non-volatile memory. Use the DATA:CAT? command to list all waveforms currently stored in volatile and non-volatile memory.

782Cannot overwrite a built-in arb waveform

You cannot overwrite the names of the five built-in arbitrary waveforms. The following names are reserved and cannot be used with the

DATA:COPY command: SINC, NEG_RAMP, EXP_RISE, EXP_FALL, and

CARDIAC.
