Using Trigger Signals - HP MC68040 User Manual

Using Trigger Signals

The HP 64700 contains two internal lines, trig1 and trig2, that can carry trigger
signals from the emulator or analyzer to other HP 64700s on the Coordinated
Measurement Bus (CMB) or other instruments connected to the BNC connector.
You can configure the internal lines to make connections between the emulator,
analyzer, CMB connector, or BNC connector. Measurements that depend on these
connections are called interactive measurements or coordinated measurements.
• To configure the internal trig1 and trig2 lines, you must access the emulation
configuration, either by choosing Modify→Emulator Config ... in the graphical
user interface and then selecting Interactive Measurement Specification, or by
entering the modify configuration command in the softkey interface, and then
answering "yes" to the "Modify interactive measurement specification?" question.
In the softkey interface, the following display appears.
BNC <<-??->> ---\
CMBT <<-??->> ---|
Emulator <<------ ---|
Analyzer ------>> ---/
NOTES:
1. The connections marked "??" are set up here in configuration.
2. drive = ---->>
STATUS: Interactive Measurement Specification_________________________........
Should BNC drive or receive Trig1? neither
_drive__ receive_ neither_ __both__
This display illustrates the possible connections between the internal lines (trig1
and trig2) and the emulator, analyzer, and external devices.
