How can I clear the data buffer memory of the E4980A when an error message "E90: Data buffer overflow" appears?
There are two ways to clear the data buffer memory.
a) Use GPIB command :MEM:CLE DBUF
b) Press front panel keys as follows:
1. [Save/Recall] hardkey
2. SAVE DATA softkey
3. SAVE & STOP softkey.
If you follow the method b) without inserting an USB memory stick, another error message "E82: Store failed" will be displayed. But the data buffer memory is correctly cleared by performing this procedure.
