MI FILTER
The optional EMI filter (Opt. 05, also called
9kHz/120kHz RBW) is a factory installed optional item
used for specific measurement situations such as EMI
average detection, where a higher level of sensitivity is
required than the standard configuration. When this
module is installed, the GSP-830 acquires two additional
features: Average/Quasi-peak detection mode, and
9k/120k RBW.
