numbers are returned in two ways:
1) Error numbers are displayed on the front panel.
2) Error numbers and messages are read back with the SYSTem:ERRor? query. SYSTem:ERRor?
returns the error number into a variable and returns two parameters, an NR1 and a string.
The following table lists the errors that are associated with SCPI syntax errors and interface problems.
It also lists the device dependent errors. Information inside the brackets is not part of the standard
error message, but is included for clarification. When errors occur, the Standard Event Status register
records them in bit 2, 3, 4, or 5:

-222 Data out of range [e.g., too large for this device]
