Extended Frequency Coverage (9 kHz to 3.6 GHz)

The 3.6 GHz upper frequency limit gives you complete coverage of critical ISM bands, including 2.4 GHz Wi-Fi, Bluetooth, Zigbee, LoRa, cellular bands up to 3G/4G, and most commercial/industrial RF applications. This eliminates the need to purchase multiple specialized instruments, providing a single solution for your entire RF development workflow from initial prototyping to final verification. The extended range also covers emerging applications and provides headroom for future wireless technologies.

Extended frequency coverage from 9 kHz to 3.6 GHz

Exceptional Sensitivity (DANL as low as -164 dBm)

Identifying weak signals is crucial in addressing interference issues, optimizing receiver sensitivity, and validating EMC compliance. With DANL values reaching -164 dBm (with preamp on), you can detect signals that would remain hidden on lesser instruments, giving you confidence in your designs and troubleshooting capabilities. This level of sensitivity is particularly valuable when working with low-power IoT devices, where signal strength is intentionally minimized to conserve battery life.
