The LB5940L is a true-RMS power sensor designed for RF and microwave measurements from 9 kHz to 40 GHz, with a calibrated dynamic range of -60 dBm to +26 dBm. It features a 2.92 mm male connector and typically exhibits a VSWR of 1.28:1 at 40 GHz. The sensor uses thermally stabilized RMS detection with no required user zeroing and maintains accuracy across temperature variations. It supports USBTMC and USB HID interfaces, and includes optional SPI, I2C, and analog recorder output interfaces for embedded and unattended applications. The device is compatible with SCPI commands and operates with Windows, Linux, and other platforms. Maximum continuous average power is +26 dBm (400 mW), with a damage level of +29 dBm (800 mW). Initial stabilization requires a 30-minute warm-up for specified accuracy.
The LB5940L True RMS, high sensitivity, high accuracy RF & microwave power sensor has frequency coverage from 9kHz to 40 GHz and an 80dB dynamic range making ideal for EMC applications, general purpose average power and scalar measurements. The sensor features a fast measurement speed, a broad dynamic range, and the widest set of options for programmatic and embedded applications in the industry. LadyBug’s feature rich Power Meter Application is provided with each sensor. Time domain trace visibility is included and aids in setting markers. The sensor is useful in research & development, manufacturing & service applications including radar, satellite and telecommunications.
Recommended for average power measurements on signals of any modulation type including: 802.11ac, gsm, cdma 2000, CDMA (IS-95), TDMA, Multi-Tone, OFDM, CW, QAM and more.
