High Accuracy Thermally Stable RF Power Sensor

LadyBug Technologies, LLC a leader in the design and manufacturing of high accuracy USB power sensors announces the expanded dynamic range of its LB5926A 1 MHz to 26.5 GHz power USB sensor. The sensor measures power down to -60 dBm and up to +26 dBm, giving it a world class 86 dB dynamic range. Further, the conservative noise floor rating means that the full dynamic range is easily used with no drift and reduced capture time requirements.

Thermal Stability

The LB5926A’s patented zero and thermal processes eliminate drift associated with high sensitivity detection technology. The sensor remains stable over its entire operating temperature range of 0°C t0 +55°C. Uncertainty is specified over the entire operating temperature range and over the full measurement range with no user or automatic zeroing / calibration. Unlike competitive sensors with internal zeroing and calibration features, the sensor is aware of the conditions around its noise floor and constantly adjusts itself. This eliminates interruption of measurements for zeroing,

Not affected by signal modulation:

The multi-path sensor utilizes diodes operating in square law and makes measurement’s similar to thermal sensors, but much faster and of a much greater dynamic range. The signal is accurately measured regardless of the modulation content, for example a signal with 300 MHz bandwidth content is accurately measured. The sensor’s accuracy, dynamic range and speed make it ideal for a wide variety of applications.  

Software and Connectivity:

The sensor is shipped with a full complement of software including an easy to use application that supports multiple sensors can be used to implement a full array of triggering features.  To aid system developers, an Interactive IO program is provided. In addition to these tools, LadyBug provides support code to help developers get started quickly. The LB5926A utilizes an advanced composite USB interface and enumerates as both a USB HID device and a USBTMC device.

Special Persona feature:

The sensor’s identification parameters can be programmed by the user. This “Persona” feature allows the sensor to be connected directly to many test instruments such as Sources, Network Analyzers, Spectrum Analyzers, and more. Applications such as automated calibration and source leveling are possible.
