where:
phs
= Program Header Separator,
digit
= one of the ASCII-coded numerals,
user message
= any message up to 63 bytes maximum.
Note
The slash-delimited /^END/ box is not outlined. This is to draw attention to the fact that it is not a data element, but represents the
EOI line being set true with the last byte 'NL' to terminate the program message.
Refer to the Standard document IEEE Std 488.2-1992, Sub-section 7.7.6, page 78.
6.C.10
Protected User Data — Entry of User Data
This command conforms to the IEEE 488.2 standard requirements.
Execution Errors
∗
PUD is executable only when the rear panel calibration switch
is in the enabled position and calibration has been enabled.
Otherwise an Execution Error is returned.
Command Errors
A Command Error is returned if the user message exceeds 63
bytes, or if the data does not conform to the standard format.
Power On and Reset Conditions
Data area remains unchanged.
∗
PUD
allows a user to enter up to 63 bytes of data into a protected area
to identify or characterize the instrument. The two
representations above are allowed depending on the message
length and the number of ‘digits’ required to identify this. The
instrument must be in calibration mode for this command to
execute.
The data can be recalled using the
∗
PUD? query.
