Self answer: WRONG !
The antenna output is extremely weak.

DSO138 showing 50 Hz signal even witout connections
Dear All,
my DSO138 is powered by a 9V transformer that stabilise 50Hz the 220 AC current and delivers 9V DC.
When I connect the provided probe to the DSO138, then I can observe a clear 50Hz signal in the display even without attaching the probe to anything.
Is this "normal" ?

DSO138 measuring of 134,2kHz signal emitted from RFID sender
Dear all,
I would like to check with the DSO138 what signal is emitted and is received from the 134,2 kHz RFID sender of my pet-door.
I was thinking to connect the DSO138 probe to the pet-door antenna poles, and then collect the signal with/without the RFID card.
Any opinion ?

DSO138 usage of UART RX TX to stream to USB
Dear All,
I would like to be able to collect the data that the DSO138 is showing on its screen.
This is something that is possible with the DSO138mini, connecting to the UART RXTX. I was wondering if anybody has already tried out the same approach also on the DSO138.
