Anritsu MA24208A – Microwave Universal USB Power Sensor

The Anritsu MA24208A is a microwave universal USB power sensor delivering precise average and True-RMS power measurements across 10 MHz to 8 GHz. Its patented triple-path architecture enables modulation-independent measurements of CW, multi-tone, and digitally modulated signals with 80 dB dynamic range and measurement uncertainty of 0.14–0.15 dB (K=2). The sensor captures >1,600 continuous readings per second or >11,000 buffered readings per second with 8 µs rise time and 140 kS/s sample rate. No zeroing is required for signals above −45 dBm. Internal and external triggering - including latching for pulses as narrow as 20 ns - enables time-dependent measurements on GSM, WiMAX, TD-SCDMA, and LTE signals. Maximum power handling reaches +30 dBm CW and +34 dBm peak (1,600 readings/s (continuous); >11,000 readings/s (buffered)
