You can watch the video here: [46 Minutes] youtu.be/qaN1f8G--zc The video description: In this episode Shahriar looks at the ecosystem of R&S power sensors & power meter. In particular, the NRP Triple-Diode Path Power Sensor & the unique NRQ6 Frequency Selective Power Sensor: https://www.rohde-schwarz.com/us/products/test-and-measurement/rf-and-microwave-power-sensors/rs-nrpxxs-sn-sn-v-three-path-diode-power-sensors_63493-99587.html https://www.rohde-schwarz.com/us/products/test-and-measurement/rf-and-microwave-power-sensors/rs-nrq6-frequency-selective-power-sensor_63493-533642.html The R&S NRX Power Meter can be used to interface with a wide range of power sensors as well: https://www.rohde-schwarz.com/us/products/test-and-measurement/power-meter-base-units/rs-nrx-power-meter_63493-533644.html This review is organized as follows: 00:00 – Introductions. 00:40 – NRP40SN 3-Path Diode Power Sensor hardware overview. 01:21 – Triple-Diode sensor architecture, benefits, principle of operation. 05:59 – Experiment setup, AM modulation glitch, web interface design, power measurements, high-sampling rate, trigger setup, trace view, R&S Power Viewer windows software. 16:17 – NRQ6 Frequency Selective Power Sensor hardware overview. 17:10 – NRQ architecture, principle of operation, advantages & disadvantages, DSP functions. 21:51 – Experiment setup, multi-frequency signal generation & interference, blocker signals. 23:33 – Web GUI interface, Signal Check function, auto-set, IF BW setup, I/Q, trace view, attenuation & averaging, blocker signal impact, catching frequency hopping events, ACLR measurements, additional features. 37:19 – NRX Power Meter overview & teardown. 40:49 – Experiment setup, input VSWR & power amplifier output power measurement. 40:01 – NRX GUI, multi-sensor measurement, sensor setups & measurement features. 45:48 – Concluding remarks. |
| Hugoneus:
Someone asked me if connecting to the NRQ6 to the NRX gives you the frequency selectivity, the short answer is yes. But I could not find any control over the IF BW in the GUI of the NRX. I will asked R&S as well. |

These are really cool! I wonder what factors go in to making a receiver capable of competing with traditional power sensors on accuracy and stability. Getting rid of YIGs is probably the bulk of it, and then at the very least a lot of validation... but I wonder what else there is. Just how far could one go with a calorimeter, some good attenuators, and a batch of RTL-SDRs? Not to 40GHz, but it might be a fun project. |

I always really like new product categories. |
