C-1200 is the first multi-channel LoRa-specific 1U rackmount tester for transmitter and receiver signal evaluation

Saelig Company, Inc. has introduced the GWInstek C-1200 LoRa Tester – a one-box tester that incorporates a multitude of LoRa transmit and receive tests. The C-1200 provides transmitter tests that include spectrum analysis, time domain, FEI (Frequency Error Indicator), and TOA (Time-On-Air).  LoRa Receiver tests include sensitivity, BER (Bit Error Rate), and PER (Packet Error Rate). In addition to sub-GHz frequencies, the C-1200 also supports the 2.4GHz band and the FSK signal test. Users can easily edit the transmitted test payloads.  Receiving data formats supported include binary/HEX, and ASCII code, which allows data transmission results to be easily verified.  A useful transfer box C-1201 is also available for easy connection of the C-1200 to a LoRa module being tested and controlled via UART/SPI/I2C interfaces.

The C-1200 can directly perform LoRa transmission signal measurement in the frequency domain as well as the time domain. In the frequency domain, LoRa’sCSS (Chirp Spread Spectrum) signal spectrum can be directly displayed; in the time domain, signal changes within a set time range can be displayed.

LoRa transmission signals may encounter a frequency error caused by environmental factors, resulting in a decreased sensitivity or loss of a packet. FEI can be used to measure the DUT transmission frequency error , so that adjustments or corrections for this error can be made during production or quality control, ensuring communication quality in deployed LoRa networks.  With four sets of half-duplex RF TRX test channels in the C-1200, it is ideal for end-of-line testing of LoRa products.
