Hint:
Together with the
Peak
display setting the Receive Signal Generator's
“Noise” setting allows you to display the actual shape of your audio
passband filter. To do so, set your PowerSDR display to
Spectrum
,
activate
Peak
and set the
Receive Signal Generator
to “Noise”
with
Input
selected. After a few moments, click the
Start
button to
stop PowerSDR and select a wider filter setting to see more of your
filter.
Enable HW Signal Generator
The so called “HW” Signal Generator is an RF signal generator as opposed to the AF Signal Generator
described above. Check to activate the HW Signal Generator, enable
SPLT
and adjust its frequency by
using
VFO B
.
Note 1:
The Receive AF
Signal Generator
must be set to “Soundcard”, to use
the RF
HW Signal Generator
.
Note 2:
In actual fact, the RF signal is generated using the transmit DSP and
sent through the QSE (Quadrature Sampling Exciter), which is then
looped back to the QSD (Quadrature Sampling Detector) and the
receive DSP.
