Re: Is there documented process to fully test QMX+ ?
|
Added info - We finished assembling the QMX+. ?When performing the ADC I/Q test we observe no I phase present on all bands(flat line). ?Q phase looks fine. ?Looking at the possible trouble shooting issues it would indicate faulty pre-amp or defective PCM1804. We do not currently have an oscilloscope available. ?We are wondering if it is a component we installed that may be the culprit. ?
Based on another thread, we rechecked the trifilar and tested for 2.7 volts on pin 1 and 7 on IC405 and IC406.?
?
Thank you
