Programming Hints - HP 3468A Operator's Manual

Instructions are implemented as they are received over the loop interface. in other
words, the 3468A will be set to the ac volts function before it is set to the
lowest range. It will be set to the lowest range before autoranging, etc.
The complete string is sent to the 3468A by loading the string into the Alpha
register and executing the command OUTA:
ALPHA FORTRAIN4T2 ALPHA
XEQ] [ALPHA] OUTA [ALPHA
Programming Hints
When more than one command is sent to the 3468A in one string, the commands
are executed as they arrive. Therefore, it is best to make the trigger statement the
last statement
in the string. In this way, the
3468A will be set up for the
measurement, before the the multimeter is triggered. If you send the command
""F2F3", the F3 command is the last one received and will be in effect.
Commands that require arguments, such as the D2 command, are exceptions to
the above rules. Any ASCII character may be sent as part of the D2 text message.
Note, however, that the 3468A display recognizes only the lower six bits of the
ASCII code, see Appendix B.
