The 3730B Down Converter and plug-in RF modules (sold separately) provide RF to IF conversion and RF test capabilities for MLAs. The 0.7 to 14.5GHz RF range of the 3730B is achieved by a series of local oscillator plug-ins, allowing easy tuning to the desired operating frequency. When equipped with the 3738B RF Module (sold separately) the 3730B's frequency range is 5.9 to 11.7GHz. The 3730B has dual IF capability which allows the Down Converter to interface with single 70MHz IF or dual 70/140MHz IF MLAs, or with wideband demodulators when white noise loading. A tracking AFC and recovered sweep facility causes the local oscillator in the 3730B to track the incoming swept RF signal, thus almost eliminating the swept component of the IF signal. This feature is particularly useful in wideband applications. It allows the Down Converter to be used in conjunction with an Up Converter and a conventional MLA to perform RF to RF measurements over bandwidths of up to 250 MHz.
