6-17
Parameter: <value> (decimal equivalent of the ESE byte, 0 to 255)
Example:
*ESE 140
Load decimal 140 (binary
10001100
) to enable bits 7 (PON), 3 (DDE) and 2 (QYE).
*ESE?
Sequential Overlapped
Coupled
IEEE-488 RS-232
x x x x x
(Event Status Enable query) Returns the contents of the Event Status Enable (ESE)
register. (See “Event Status Enable Register (ESE)” in Chapter 5)
Response: <value> (decimal equivalent of the ESE byte, 0 to 255)
Example:
*ESE?
returns
133
Returns decimal 133 (binary
10000101
) when bits 7 (PON), 2 (QYE), 1 (OPC) are
enabled.
*ESR?
Sequential Overlapped Coupled IEEE-488 RS-232
x x x x
x
(Event Status Register query) Returns the contents of the Event Status Register (ESR)
and clears the register. (See Event Status Register (ESR)” in Chapter 5)
Response: <value> (decimal equivalent of the ESR byte, 0 to 255)
Example:
*ESR?
returns
189
Returns decimal 189 (binary
10111101
) when bits 7 (PON), 5 (CME), 4 (EXE), 3
(DDE), 2 (QYE) and 0 (OPC) are enabled.
EXPLAIN?
Sequential Overlapped Coupled IEEE-488 RS-232
x x x x x
(Explain Error query) Explains an error code. This command returns a string that
explains the error code furnished as the parameter. The error code (same as the
parameter) is originally obtained by sending the
FAULT?
query. (See the
ERR?
command, which returns both the error code and the explanation string.) See Appendix E
for a list of error codes and error messages.
Parameter: <value> if the error code (an integer)
Response: <string> that explains the error code, with the parameter (if there is one)
shown as a percent sign followed by d (integer parameter),
f (floating point parameter), or s (string parameter)
Example:
EXPLAIN? 539
returns “
Can’t change compensation now.
”
Returns the explanation of error 539: “Can’t change compensation now.”
EXTGUARD
Overlapped Coupled IEEE-488 RS-232 Sequential
x x x x x
(External guardcommand) Connects or disconnects the internal guard shield from the LO
binding post.
Parameter:
ON
(external guard is on, i.e. external)
OFF
(external guard is off, i.e. internal)
Once set, the Calibrator retains the external guard setting until power off or reset.
Example:
EXTGUARD ON
