Not quite; what does it look like on a 'scope? Can you display the pulse
from perhaps, an IF output? Even simpler, try connecting a 'scope
directly to the antenna; you may or may not need a broad band preamp
ahead of it.
It is quite often useful to know what interference looks like not on a
waterfall or even a spectrum analyzer, but at the scale of its pulse
length, perhaps 2, 5 or 10 msec per division.

Cortland,
What do you mean? Do you want to know how much time goes by on the
vertical axis?
It takes about 25 seconds for the spectrum to scroll by when it is
probably 400 pixels tall - so 16 pixels per second. It looks like the
pulses are between 1 and 5 pixels tall - so 1/16th to 5/16th of a
second (not sure if the AGC affects this).
