GR-301 Digital Radio Broadcast Monitoring Receiver

Features

l Supported Standards: DRM30, AM, FM

l Measurements:

Support DRM key parameters, including MER, SNR, RSSI, audio frame error rate, etc.

And AM/FM analog broadcast indicators such as RSSI, frequency offset, modulation, etc.

Supports obtaining time and geographic location information from an external GPS antenna.

l Live audio: DRM/AM/FM audio can be compressed losslessly and uploaded to the server. Local listening is also supported.

l High performance RF frontend: high-dynamic 6 bands RF frontend circuit design.

l Remote control: The receiver can be remotely controlled and scheduled for tuning through the data analysis platform.

l Data transmission: Support output RSCI or MDI/DCP multiplexed stream, 10/100M adaptive Ethernet connection, support data failure retransmission and local cache, optional 4G module or Wi-Fi connection.

l Network Automatic configuration: Automatic configuration and networking when power on, manually reconfigure no required.

l External interfaces: antenna interface (50 ohm BNC), antenna bias power supply, audio output, USB, AC and DC input, RS232 serial port, local monitor, GPS antenna, relay output.

l HMI: The LCD interface displays the working status, and the operation panel can be selected to be locked when working in the remote state.
