This voltage is sent to the 85309B where it is displayed in the DETECTOR VOLTAGE display. The voltage is directly proportional to the amount of LO power.
Operating Information 85309B Front Panel Features LO/IF Distribution Unit 85309B LO POWER OUT OF RANGE When lit, this LED indicates that the LO source is not supplying the amount of LO power requested by the LO POWER ADJUST control. The LO POWER OUT OF RANGE circuit compares the LO POWER ADJUST setting with the voltage coming back from the reference detector. The amount of expected detector voltage varies depending on the LO POWER ADJUST setting.
