You should not make any adjustments as this requires more precise measurement instruments than 8920A. --- End quote --- Got it, I'm not going to make any adjustments, I mean those adjustable resistors, adjustable capacitors. |

Based on yesterday's maintenance experience of cleaning P102, do P101 and P103 also need to be disassembled and cleaned like yesterday? Because I saw P103 has a "LO SENSE" mark |

Please check it again with 50 Ohm load at the input. |
