Help with Noise Generators and Sources specifications:

Device Type
   Device Type       
   Your choices are...         
   Noise Generator       Noise generators are benchtop or rack-mounted, manual or microprocessor-controlled instruments that generate noise and allow users to control the amplitude manually with front panel controls or remotely with a general-purpose interface bus (GPIB) or RS232 bus. Eb/No or C/N noise generators are more complex because they accurately set a user-specified signal-to-noise ratio. 
   Noise Source       Noise sources are package parts that contain all of the required biasing circuitry so that only a positive bias voltage and ground is needed to generate the noise signal. Noise sources are available in coaxial, waveguide, pin and surface mount packages. 
   Noise Diode       Noise diodes are semiconductor devices that require biasing circuitry in order to generate a noise signal.

Signal Characteristics
   Minimum Frequency Range       The minimum frequency range is the range of output frequencies that a generator can produce. 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Maximum Frequency Range       The maximum frequency range is the range of output frequencies that a generator can produce. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Amplitude       Specifies the range of output amplitude the device can produce. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Frequency Resolution       Frequency resolution is the smallest frequency increment the generator can produce. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.

Form Factor
   Form Factor       
   Your choices are...         
   Portable / Benchtop       Portable or benchtop devices can be moved with relative ease for a variety of uses. They include a case or handle, but are not necessarily hand-operated. 
   Rack Mount / Fixed       Devices mount in racks and come with hardware such as rail guides, flanges, or tabs. Some rack-mounted devices fit in a standard 19” telecommunications rack. Fixed devices are meant to be used in one place. 
   Printed Circuit Card       Devices are printed circuit boards (PCBs) that attach to enclosures or plug directly into computer backplanes. 
   Coaxial       Connectorized for transmission lines carrying high-frequency signals. 
   Waveguide Component       Waveguide components are circular, elliptical, or rectangular metal tubes or pipes through which electromagnetic waves are propagated in microwave and radio frequency (RF) communications. 
   Other       Other unlisted form factors. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

User Interface
   User Interface       
   Your choices are...         
   Manual Controls       Manual controls are located on the device's housing. 
   CPU Controlled / Computer Programmable       A central processing unit (CPU) or microprocessor controls the device. The microprocessor can be either an embedded processor or an external controller. The device may also be controlled by or directly interfaced to a personal computer (PC) or workstation. Generally, this is done for programmability and datalogging.   
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
