No output from module

[CDutescu]

First and foremost, I want to express my gratitude for your effort in developing this library for the MAX2870 chip. I am currently working on configuring the MAX2871 chip in a MAXREFDES161, which comes equipped with a built-in 50MHz oscillator. I've utilized the convenient spreadsheet provided in this repo, specifically in conjunction with the "FREQ_DIRECT 1 50 1 0 1 0 TRUE" command. In sequence, I've executed the following commands, receiving "OK" responses:

1. CE ON
2. STATUS
3. REF 50000000 1 UNDIVIDED
4. FREQ 1000000000 1 1 FUNDAMENTAL 0 0

Despite running these commands, I have not been able to observe any output from either Output A or B on my Evaluation Board. I would greatly appreciate any guidance or assistance in generating an output signal.
