• Connectivity: Gigabit Ethernet, USB-OTG, USB-UART, USB-JTAG

Physical Setup and Initial Connections

1. Power Connection: Connect the DC power adapter to the E310. The device should boot automatically (watch for LED activity).
2. Antenna Installation: Connect the 4 included antennas to the SMA connectors (TX1/RX1, TX2/RX2). For testing, use all four ports.
3. Network Setup: Connect Ethernet cable between E310 and your network/PC. The device boots with default IP 192.168.1.10.
4. Console Access: Connect micro-USB cable to access serial console at 115200 baud (optional but recommended for troubleshooting).

Network Configuration and Access

1. Configure Your PC Network: Set your computer's Ethernet adapter to static IP in same subnet:
   • IP Address: 192.168.1.100 (any unused address)
   • Subnet Mask: 255.255.255.0
   • Gateway: 192.168.1.1
2. Verify Network Connection: Test connectivity with:

   ping 192.168.1.10

3. SSH Access: Connect to the E310 for advanced configuration:

   ssh [email protected]

   Default password: analog

Firmware Setup and Updates

1. Check Current Firmware: Via SSH, run uhd_find_devices to verify UHD installation.
2. Update Firmware (if needed): Download latest firmware from MicroPhase GitHub.
3. SD Card Preparation: Copy firmware files to FAT32-formatted SD card and insert into E310.
4. Reboot and Verify: Power cycle the device and confirm new firmware loads successfully.

First Reception Test

1. SSH into E310: Connect via ssh [email protected]
2. Launch GNU Radio: The E310 has GNU Radio pre-installed. Create a simple flowgraph:

   gnuradio-companion

3. Basic RX Flowgraph: Create flowgraph with:
   • UHD: USRP Source (device args: blank for local operation)
   • Sample Rate: 2e6 (2 Msps)
   • Center Frequency: 100e6 (FM broadcast band)
   • Connect to Audio Sink for monitoring
4. Execute and Verify: Run flowgraph and confirm FM radio reception

First Transmission Setup

1. Create TX Flowgraph: In GNU Radio Companion, add:
   • Signal Source: Sine wave at 1 kHz, amplitude 0.5
   • UHD: USRP Sink with TX frequency (e.g., 433 MHz ISM band)
   • Sample Rate: 2e6
   • TX Gain: Start low (10-20 dB)
2. Safety Precautions:
   • Use dummy load or attenuator for initial testing
   • Verify frequency is legal for your location
   • Keep TX power low during testing
3. Execute Transmission: Run flowgraph and monitor with external receiver or spectrum analyzer

Remote Operation from PC

1. Install UHD on Host PC: Download and install UHD with E310 support from MicroPhase UHD repository.
2. Network UHD Connection: Use device arguments addr=192.168.1.10 in GNU Radio on your PC.
3. Test Remote Operation: Verify you can control E310 from host computer GNU Radio installation.

MIMO Configuration and Testing

1. Dual-Channel Setup: Configure both RX and TX channels in GNU Radio:
   • Use num_recv_frames=2 for dual RX
   • Set antenna ports: "RX1", "RX2" for receive channels
   • Ensure identical sample rates and synchronization
2. Antenna Placement: Space antennas appropriately for MIMO effectiveness (≥λ/2 separation).
3. Phase Coherency: Perform calibration for applications requiring phase-matched channels.

Advanced Applications

• Cellular Research: Deploy srsRAN for LTE base station development
• WiFi Prototyping: Use OpenWiFi for 802.11 research
• Custom Applications: Develop standalone applications using the onboard ARM processors
• FPGA Development: Utilize Zynq-7020 FPGA for custom signal processing

Performance Optimization

• Thermal Management: Ensure adequate cooling during sustained high-power operation
• Network Bandwidth: Use Gigabit Ethernet for high sample rate streaming
• Buffer Management: Adjust buffer sizes for stable operation at high data rates
• Power Supply: Use quality 12V/2A+ supply for consistent performance

Troubleshooting Common Issues

• Network Connection Failed: Verify IP configuration, cable connections, and firewall settings
• No RF Output: Check antenna connections, TX gain settings, and frequency permissions
• Poor Performance: Ensure adequate power supply and proper thermal management
• Firmware Issues: Use serial console to monitor boot process and diagnose problems

Serial Console Access

1. Install Terminal Software: Use PuTTY (Windows) or screen (Linux) for serial access
2. Configure Connection: Set baud rate to 115200, 8N1
3. Monitor Boot Process: Watch system startup messages for troubleshooting
4. System Commands: Use ifconfig, uhd_find_devices for network and UHD verification
