SDR Console V3 Gain/LNA signal strength visualization issue

#1

Unread post by navman45 »

The signal I am testing/visualizing is an uplink cellular phone rf signal, but regardless of the signal type, there is a significant RF signal strength difference between what I can see in the Console vs a Realtime Spectrum Analyzer (multiple RTSA spectrum analyzers).
As you can see in the image, the Console shows the signal at about -110dbm, while the spectrum analyzer displays the signal at -45dbm (both HackRF and RTSA are placed at the same distance from the transmitter). The Console even needs the LNA at 32db to even show the signals. The Console is connected to a HackRF SDR unit.
Being such a significant difference between readings, is there any know issue or setting that I am missing?
Thanks.
