RX Parameter Testing Basics
To investigate the RX performance of the CC2530, you can use a signal generator or “Packet TX” in
SmartRF Studio (with another EB+EM) to generate the packets to receive. The receiver
can be
configured by using the “Packet RX” test feature in SmartRF Studio.
By adding a jammer (a third node that generates either noise on the same channel or a strong signal
on an adjacent channel) it is also possible to measure co
-
channel rejection and
selectivity/blocking
performance.
The PER test application, that was described in section
5.3
, can be used for simple sensitivity
measurements with the CC2530EM
and/or with your own prototype hardware. In this case, connect
the unit you want to test to a known good transmitter with coaxial cables and attenuators. Add more
attenuators until the PER value is 1%. The signal strength at the receiver side is then the s
ensitivity
limit of the system.
