Additional RBW filters A-B-3A-B.3.3 MIL Filtersover 30MHzUsing PMM 9030, PMM 9060, PMM 9180, and PMM 9010/03P/30P/60P over30 MHz, the 10 kHz, 100kHz and 1MHz filter are MIL-STD-461E (they are notoptional but always available). The 1MHz filter is also CISPR 16-1-1 compliant(B-imp).A-B.4 Manual Mode The MANUAL mode is a very useful feature to manually control the receiverand to deeply investigate electrical signals modifying the parameters ofreceiver exactly as per the needs of the Test Engineer.It is possible, for example, to observe the signals exceeding the limitsfrequency by frequency; evaluating their levels measured simultaneously with3 different detectors (Peak, RMS and Average); listening to them after ademodulation, etc.To enter in Manual Mode press the key in the main menu.A-B.4.1 RBWSelectionThe Manual mode function has five sub windows:• Frequency• Level• Resolution Bandwidth• Hold Time• DemodulationAlways use Esc button to return to the previous view/condition.A-B.4.2 MIL Filters The Resolution Bandwidth command is used to select the bandwidth of themeasuring filter.The three larger filters are selectable from the first RBW screen, and pressingthe More RBW button it is possible to select all the other filters.These filters are mathematically modeled using FIR (Finite ImpulseResponse) technique and they are exactly as required by the standards.Four additional bandwidth filters are now available:• 10 Hz MIL at -6dB• 100 Hz MIL at -6dB• 1 kHz MIL at -6dB• 10 kHz MIL at -6dBWhen a non-CISPR filter is selected, the Quasi Peak, C-RMS and C-AVGdetectors are disabled.
