The 7L18 will NOT do 1.5 GHz to 18 GHz in one span, it will only max span the range selected by the BAND/HARMONIC control. This range is determined by the heterodyne harmonic number and sign (sideband) and the range of the first LO, which is 2 GHz to 4 GHz. | |||
The input attenuator is a standard Weinschel Engineering product driven by a belt. | |||
The range is encoded for the digital dBm reference level display. | |||
The signal then passes through a YIG preselector filter with a 50 MHz bandwidth. | |||
After the YIG filter, the signal enters the RF input of the mixer assembly. | |||
