  13. RF910 Pre-selector units RF910 and RF915 As specified by CISPR16 and recommended for conducted emission measurements if the EUT produces broadband noise. These pre-selectors effectively pre-filter the incoming signal such that the analyser input is not overloaded by broadband energy. Not required if EUT produces narrowband noise. RF910 covers band B (150KHz – 30MHz) RF915 covers bands A and B (9KHz – 30MHz) RF1000 or RF2000 Photo shows RF910 below SA1000 and PC

  14. ERS Emissions Reference Sources These sources can be used to simply check an established site prior to measurements, or To calibrate an unknown site.
