Hi,
Could somebody let me know which will be the best probe to measure phase noise of a CMOS signal in range of 1MHz to 50 MHz, with peak-to-peak swing of 3.3V
The phase noise measurement kit which I use is E5052B. So, it has to be an active probe. I have used 85024A in the past but 3.3V swing is definitely beyond the allowed limit for it, without 10:1 divider. The noise floor I need to measure is around -150 dBc levels and thats why I had to remove the 10:1 divider. Is there anything better available?
Thanks and Regards,
Anand
