Measured radio wave of LoRa (920Mz band: LPWA)

By using the signal analyzer MSA500 series, the signal of LoRa (LPWA using 920MHz band) will be acquired.

[Application]

We received such an inquiry as "Can be measured the LoRa signal using the MSA500 series ?" and then measured it actually.
LoRa is one of LPWA (Low Power Wide Area) using the 920 MHz band, and the origin of the name comes from “Long Range”. It can communicate at a maximum of several tens of kilometers, and features low power consumption.
The LoRa signal adopts a special modulation scheme called chirp spread spectrum. Although the amplitude is constant and the frequency is changed, instead of transmitting 0 or 1 by high or low of the frequency as in ordinary PSK, 0 or 1 is transmitted using a signal (chirp signal) whose frequency continuously varies. The signal is transmitted by combining a signal of frequency becoming high (up chirp) and a signal of frequency becoming low (down chirp).
