amplitude too low ? If the signal on the
spectrogram is, for example, 90 dB below "full
scale" you will hardly see it on the scope, with
its linear scaling.
(too little time to test this myself. too busy
from other projects ... maybe later..)

I am generating a 10KHz signal (sine wave)
from a frequency generator and pushing it to
an antenna. I can see the received signal
on the waterfall in Spectrumlab. I then
show the filter passbands and setup the
filter only to include the bandwidth of the
received 10KHz signal.
I bring up the Time domain scope and and
select L4=Left Filter. There are no other
input channels. Looking at the oscilloscope
output, I observe a straight line, rather
than the sine wave of the received 10KHz
signal. I have tried zooming in, but I
observe no change in the oscilloscope
Am I doing something wrong?
