GWINSTEK C 1200 MULTI CHANNEL LORA TESTER

GWINSTEK C-1200 MULTI-CHANNEL LORA TESTER

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, […]

Arduino Frequency Detection

As a follow up to the Arduino Audio Input tutorial that I posted last week, I wrote a sketch which analyzes a signal coming into the Arduino’s analog input and determines the frequency.  The code uses a sampling rate of 38.5kHz and is generalized for arbitrary waveshapes.  I’ve also turned the LED attached to pin
