Character data not allowed
A discrete parameter was received but a character string or a numeric parameter was
expected. Check the list of parameters to verify that you have used a valid parameter
type.
For example, MEM:CLE CUSTOM_1.
Invalid string data
An invalid string was received. Check to see if you have enclosed the character string in
single or double quotes.
For example, MEM:CLE "CUSTOM_1.
String data not allowed
A character string was received but is not allowed for the command. Check the list of
parameters to verify that you have used a valid parameter type.
For example, LIM:STAT 'ON'.
Invalid block data
A block data element was expected but was invalid for some reason. For example,
*DDT #15FET. The 5 in the string indicates that 5 characters should follow, whereas in
this example there are only 3.
Block data not allowed
A legal block data element was encountered but not allowed by the power meter at this
point.
For example, SYST:LANG #15FETC?.
Expression data not allowed
A legal expression data was encountered but not allowed by the power meter at this
point.
For example, SYST:LANG (5+2).
Trigger ignored
Indicates that <GET> or *TRG, or TRIG:IMM was received and recognized by the device
but was ignored because the power meter was not in the wait for trigger state.
