Programmable DC Power Supply (with Solar Array Simulation) 62000H Series
Operating & Programming Manual
5.3.5.7 Program Message Unit
A program message unit represents a single command, programming data, or query.
Example: VOLT?, OUTPut ON.
5.3.5.8 Program Message Unit Separator (;)
The separator (semicolon ;) separates the program message unit elements from one another
in a program message.
Example: VOLT 80; CURR 15<PMT>
5.3.5.9 Program Message Terminator (<PMT>)
A program message terminator represents the end of a program message. The three
terminators are:
(1) <END> : end or identify (EOI)
(2) <NL> : new line which is a single ASCII-encoded byte 0A (10 decimal).
(3) <NL> <END> : new line with EOI.
The response message is terminated by <NL> <END> for GPIB, and
<NL> for RS-232C.
5.4 Traversal of the Command Tree
Multiple program message unit elements can be sent in a program message. The first
command is always referred to the root node. Subsequent commands refer to the same tree
level as the previous command in a program message. A colon preceding a program
message unit changes the header path to the root level.
Example:
SOURce:VOLTage:SLEW 1 All colons are header separators.
:SOURce:VOLTage:SLEW 1 Only the first colon is a specific root.
SOURce:VOLTage:SLEW 1;:VOLT 100 Only the third colon is a specific root.
5.5 Execution Order
The 62000H DC Power Supply executes program messages in the order received.
