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
