Agilent Technologies E1441A Too many errors, Query UNTERMINATED after indefinite response

-350Too many errors

The error queue is full because more than 20 errors have occurred.

No additional errors are stored until you remove errors from the queue. The error queue is cleared when power has been off, or after a *CLS (clear status) command has been executed.

-410Query INTERRUPTED

A command was received which sends data to the output buffer, but the output buffer contained data from a previous command (the previous data is not overwritten). The output buffer is cleared when power has been off, or after a device clear has been executed.

-420Query UNTERMINATED

The function generator was addressed to talk (i.e., to send data over the interface) but a command has not been received which sends data to the output buffer. For example, you may have executed an APPLy command (which does not generate data) and then attempted an ENTER statement to read data from the remote interface.

-430Query DEADLOCKED

A command was received which generates too much data to fit in the output buffer and the input buffer is also full. Command execution continues but all data is lost.

-440Query UNTERMINATED after indefinite response

The *IDN? command must be the last query command within a command string. Example: *IDN?;:SYST:VERS?

501Isolator UART framing error

502Isolator UART overrun error

511RS-232 framing error

512RS-232 overrun error

513RS-232 parity error

521Input buffer overflow

522Output buffer overflow

550Command not allowed in local

You should always execute the SYSTem:REMote command before sending other commands over the RS-232 interface. This error is also generated if you attempt to execute the DISP:TEXT command while in the local mode (this command is allowed in remote only).

580Phase-locked loop is unlocked

Option 001 Phase-Lock Only. The function generator has detected an “unlock” condition. You must execute the PHAS:UNL:ERR:STAT ON
