Error Codes
The CG635 contains an error buffer that may store up to 20 error codes associated with errors
encountered during power-on self tests, command parsing, or command execution. The errors in the
buffer may be read one by one by executing successive LERR? commands. The meaning of each of the
error codes is described below.
Execution Errors
0 No
Error
No more errors left in the queue.
10 Illegal
Value
A parameter was out of range.
20 Frequency
Error
The frequency or frequency step size was illegal.
30 Phase
Error
The phase step size was illegal.
31
Phase Step Error
The phase could not be set because it would have caused a phase step larger than 360°.
40 Voltage
Error
The voltage could not be set because it was out of range.
