The Type HFX-1 Modulation Monitor is an ancillary piece of equipment, which is used with narrow bandwidth, or older oscilloscopes to allow viewing of RF signals and particularly modulated signals as high as 55MHz. The equipment contains an RF signal source and a broadband mixing circuit which converts the high frequency signal to an intermediate frequency within the oscilloscope’s range. The frequency control dial is simply adjusted until the RF signal is viewed on the scope. BNC connectors are mounted on the rear panel to allow interconnect to the scope and RF probe. This product was previously called "oscilloscope frequency extender" and may be used to view other high frequency signals on older or narrow band scopes.
