Sending Queries To The Logic Analysis System - HP 16500C Programmer's Manual

Sending Queries to the Logic Analysis System

This program example contains the steps required to send a query to the
logic analysis system. Sending the query alone only puts the requested
information in an output buffer of the logic analysis system. You must follow
the query with an ENTER statement to transfer the query response to the
controller. When the query response is sent to the logic analysis system, the
query is properly terminated in the logic analyzer. If you send the query but
fail to send an ENTER statement, the logic analysis system will display the
error message "Query Interrupted" when it receives the next command from
the controller and the query response is lost.

100 ! If your query response includes real
110 ! or integer numbers that you may want
120 ! to do statistics or math on later, you
130 ! should turn both header and longform
140 ! off so only the number is returned.
