3.4.1 - System Grounds
The Model 9002 grounding system has been designed to allow maximum flexibility and noise immunity. There are
three electrically isolated grounds brought out for connection to the external components.
Digital ground for connection to the remote controller is provided on the IEEE-488 interface connector.
Analog signal ground is brought out through a rear panel plastic banana plug and is internally connected to the unit’s
analog power supply. Analog ground provides a system ground reference for differential input configurations.
Effective grounding of signal lines and every chassis will greatly improve noise immunity and assure precise filter
spectra. A discussion of noise and distortion that accompanies the Model 9002 filter process is found in the Product
Data Sheet (Appendix A).
3.5 - Basic Setup
The Model 9002 may now be connected to the power source, to the remote controller (if remote is being used), and
to the circuit to be filtered.
1.Connect the device being filtered to the input and output BNCs on the front or rear panel. Be sure that both input
and output are hooked up to the same channel. If possible, connect a ground strap between the chassis of the
device and the Model 9002 chassis.
2.For remote operation, connect the IEEE-488 interface from the remote controller to the connector provided on the
rear panel of the Model 9002. If the controller is not already equipped with an IEEE-488 interface card, one must
be installed. Refer to the computer or controller manufacturer’s instructions for card installation.
3.Plug the unit into the power source.
4.You are now ready to learn and utilize the many features of your Model 9002 Dual Channel Programmable Filter.
The following sections contain specific control, modification, and programming information. Please read these
sections carefully before using the system.
