Introduction
The Agilent U3606A Multimeter|DC Power Supply unit is a combination of 
a 5½ digit digital multimeter and a 30 W single output dual- range  
DC power supply with a square- wave generator. These two distinctive 
modules are able to work simultaneously (excand independently, providing 
an efficient, convenient, and affordable testing solution.
The U3606A has the dimensions of 2½U (rack unit) high, and provides the 
flexibility for bench or rack- mounted use.
The front panel controls allow you to set the measurement parameters, 
mathematical operations, output parameters, protection features, and 
instrument settings.
The rear panel includes a GPIB and USB interface connector, as well as 
output terminals capable of remote sensing.
When operating over the remote interface, the U3606A functions as both a 
listener and a talker. Using an external controller (such as a PC), you can 
instruct the U3606A to make a measurement, output a source, or send 
data back over the GPIB or USB interfaces.
