A25 Wideband Analog IF Assembly Description - Option B1X and B85
The analyzer's RF input signal is down converted to a 300 MHz intermediate
frequency by the A13 Front End assembly and routed through the A15 Front
End controller to A15J901. Cable W41 connects A15J901 to the input of the
A25 Wideband Analog IF at J101. The signal is filtered, attenuation and gain
applied based upon the instrument settings. This signal is then sampled by the
ADC and the resultant data is the sent to the A26 Wideband Digital IF for
processing via the W44 flex circuit. The A26 Wideband Digital IF has no service
accessible locations and should be troubleshot from the front panel controls.
