Mini-Circuits Power Sensor - Opinions?
« on: March 31, 2020, 12:07:45 am »
I recently purchased 5 Rohde NRP USB power sensors (which are great sensors), but I am looking at the Mini-Circuits PWR-8P-RC as a lower cost alternative (about 1/2 the price) and I need at least 10 more.  I like that is supports both USB and LAN on the same sensor.  R&S and Keysight are either USB or LAN not both and LAN is higher cost.  The uncertainty appears about 50 % higher, but still good enough for my use below 3 GHz (primarily 0.5-1 GHz).  Anyone have any opinions on this power sensor as an alternative to the NRP 8S. 

I have pretty much ruled out the Keysight sensors because the software is licensed (Benchvue), I have to send these all over the country and they need to work on whatever laptop is available, not messing around with license management software, even if the license is free.

Haven't used them, but if the more limited frequency range is viable, they've certainly got a name in the industry and probably have a perfectly serviceable power sensor.

That said, two things:
Anritsu has some USB power sensor options, don't know what price is like, but they could be another competitor and have been doing power sensors for decades.

Keysight does charge for their BenchVue license, but newly purchased sensors from them come with it for free (at least, so claims their product page for some sensors).  It's something like $135 for a license otherwise, and there is a free utility at least for the U200X series sensors called "Agilent U200xA USB Power Sensor Virtual Panel" which is available for free to download from Keysight.  Don't know how wide the support of power sensors is, but it's responsive and pretty comprehensive in terms of instrument control.  The UI looks less polished and I'm sure it lacks some more advanced analysis functions, but as a basic power meter with full control over instrument settings, it does work and is free.

I don't know what BenchVue looks like, but I've got an NRP as well and do like R&S's software for it - though the asking to save a log every time I close the program is tedious when not meaning to log anything in the course of its use....
