To start an external instrument on command from a module within the HP 16500 and 16501 mainframe
You can set up a module in a group run so that it sends a pulse through the PORT OUT rear panel BNC. The pulse can be used to start or stop a measurement in an external instrument or system.
1Set up the group run specification.
See “To start a group run of modules within the HP 16500C” or “To start a group run of modules from an external trigger source.”
2Select PORT IN/OUT.
The PORT IN/OUT Setup menu appears.
3Select the PORT OUT Source field.
∙Select Off if no module should drive PORT OUT.
or
∙Select the name of the module you want to have drive PORT OUT.
If you are using Group Run with OR TRIGGER, Port Out is automatically assigned to the OR TRIGGER group.
4Set the Type, Polarity, and Output fields to generate the type of signal the external instrument expects.
To generate the same signal as a 16500B would, set Type to Feedthrough, Polarity to Active High, and Output to Normal. Normal sends out a standard TTL signal; Open Collector sinks 128 milliamps in its low state.
5Select Done in the PORT IN/OUT Setup menu.
