Viewing or Changing the GPIB Address of the Multiple Channel Controller

Installation

Selecting Positive or Negative-Edge Event Triggers

The factory default setting of the GPIB address is 9. To view the GPIB address:

Press [Select Instr] {SYSTEM} {GPIB} {READ}.

To change the current GPIB address:

1.Press [Select Instr] {SYSTEM} {GPIB} {SET}.

2.Enter the new address and press [Return].

Selecting Positive or Negative-Edge Event Triggers

By default, the positive-edge of the EVENT TRIG line starts the measurement. To change this so a negative-edge starts the measurement, perform the following procedure.

CAUTION	This device contains devices that are sensitive to static discharge. When you
	remove the cover of this device, observe static safety precautions:
	1.	Place the unit on a grounded anti-static mat.
	2.	Wear a grounded wrist strap. Foot straps are only acceptable if you wear
		one on each foot, and if you are standing on a grounded ﬂoor mat.

Refer to Figure 1-4 on page 1-9 .
