The time taken for the HP 8 1 1 2A to receive and implement a
programming message can be divided into three parts:
Send
This is the time taken to transmit the programming message over the
HP-IB, which is 130 µs ms per ASCII character (7.6 kByte / sec). The
system controller is free to continue with its program after this time.
Answer
This is the time taken by the HP 8 1 1 2Ato transmit a message when
error reporting or learn mode. Time is 1 ms per character, status
byte < 15 ms
This is the time taken by the HP81 12A to interpret and carry out all
the commands in received message. Typical implementation times
vary between ms for select mode to 1 85 ms to recall a parameter
4
set. Typical implementation times for various commands are given in
the following table.
