I can't answer the first two and Al has given the answer to the third. But, you're not going to be measuring phase noise in the strictest sense, but what ARRL calls composite-noise.  Interesting they *do* actually measure phase noise with an HP11848 Phase noise test set and then they assume

According to Al, N1AL, "The effective bandwidth of the P3 is approximately one pixel on the display, which is SPAN/468.  So, for example, if the span is 47 kHz, the effective bandwidth is about 100 Hz." To "convert" or "correct" to a 1 Hz bandwidth, use the formula: BW_correction_factor = 10 *

Hi, I am contemplating practicing some phase noise measurements using a P3. If I correctly understand the measurement, (which I may not), I should express the result, using db down from peak, so many Hz away from peak, using a 1 Hz width. First question; is the above correct? Second

BNC cables do have issues all of their own. First a manual connector seems difficult for some to terminate properly (especially the shield). Connectors have 2 sizes of center pins (50 & 75 ohm). Using a large connector and then a smaller conductor will cause an intermittent at the female center.
