Can I have Multiple Carrier Inputs Simultaneously Applied to the RF Input for an E5052B SSA Phase Noise Measurement?

Frequently Asked Questions (FAQs)SummaryDoes the Keysight E5052B Signal Source Analyzer (SSA) allow multiple simultaneous carriers on the RF input during phase noise measurements? The E5052B SSA has a "Frequency Band" input range selection, does this provide for pre-selection and filtering thus allowing frequency distributed multiple carrier inputs during a phase noise measurement?QuestionCan I have Multiple Carrier Inputs Simultaneously Applied to the RF Input for an E5052B SSA Phase Noise Measurement?AnswerMultiple simultaneous RF carriers on the input of the E5052B SSA are not allowed for successful phase noise measurements. If the E5052B SSA has multiple carriers on the input the analyzer is unable to successfully complete a phase noise measurement. Multiple RF carrier presence is not allowed on the RF input of the E5052B SSA.  There is no pre-selection or filtering on the E5052B SSA input RF connector. The use of the E5052B SSA Setup - Frequency Band -  and selecting one of the following selections does not provide pre-selection / filtering either.  If multiple carriers are present and the goal is an E5052B SSA phase noise measurement consider the use of an appropriate band pass, low pass or high pass filter to remove the non-desired carrier.
