Model 2500 and 2502 User’s Manual Connections 2-13
Isolated connections
To maintain proper isolation between the analog outputs and chassis ground, it is strongly
recommended that you use the isolated connections shown in Figure 2-11. In this case, an
Analog Devices 3B41-03 Isolated Wideband Voltage Input is used to provide isolation
between the Model 2502 ANALOG OUT and the measuring instrument. Analog output HI
(center conductor) is connected to the HI input terminal of the isolator and analog output
LO (inner shield) is connected to the LO input. The two isolator V
OUT
terminals are con-
nected to the measuring instrument HI and LO INPUT terminals as shown.
Refer to the 3B41-03 documentation for connections, power supply, and configuration
information for your application.
