*PUD
(Protected user data command.) This command allows you to store a string of
bytes in nonvolatile memory. The Calibratration secure state must be set to off.
Also see the RPT_STR command, which has a similar function, except the
RPT_STR string is printed on calibration shift reports.
Parameter
Binary Block Data
Example
To store the string "CAL LAB NUMBER 1" in the protected user data area.
*PUD #0CAL LAB NUMBER 1\<Line Feed with EOI\>
or
*PUD #216CAL LAB NUMBER 1
The 2 indicates that there are two digits to follow (in this case,
"16"), and the 16 indicates that there are 16 characters including
space characters in the remainder of the *PUD message (in this
case, CAL LAB NUMBER 1).
This type of data is called Binary Block Data in the IEEE-488.2 Standard. In
the Product, however, you don't need to use this protocol. The parameter:
"CAL LAB NUMBER 1"
works exactly the same.
*PUD?
Returns the contents of the *PUD (Protected User Data) memory. (Sequential
command.)
Parameter
None
Response
Binary Block Data. The maximum response is 64 characters.
Example
*PUD?
Returns:
"#216CAL LAB NUMBER 1"
Assuming that this is stored as in the example for PUD* above.
No wideband installed
30 MHz option installed
50 MHz option installed
