Right now I imagine there are a lot of redundant LTE test systems in the market, which have been replaced by a lot of 5G test systems. If the protocols keep moving on, the equipment has to be replaced. If the protocols hang around for a long time the equipment sees a long life. |

It's all about the calibrated product support. If you are building $100M communication satellites then you are not going to use a $10 Home Depot DMM. Well, not officially. Okay, YOU go tell the management team that you're having to slash the test equipment budget because the same management team just blew all the budget on charging points for their toy Teslas >:( Fun fact, test equipment engineers and their families need to eat too. |

It's true that demand for ultra-high-end test equipment these days is driven mainly by optical and wireless communication R&D. But not this one. This is clearly built with two very specific applications in mind: - monitoring spectrum use/tracking down interferers - military/intelligence signal interception |

I think that is paranoid nonsense. A boss wants 1 box that does it all, always. Especially when lab space is low (always is). They also always want to expand budget for good reasons (it like the tide and you wanna be prepared). Unless its the guy that says you don't need more then 50MHz 2 channels for digital and expects you to work till 9pm making 'adapters' For instance, are you sure that 5.8GHz is not making a third harmonic ? This is standard stuff nowadays, especially with 5G!!!!!! are you kidding!!! Car has 70GHz radar on it now. Do you really think a serious lab would just be happy with trusting the manufacturer that its not doing anything bad when there is all sorts of mixers and diodes in there??? For instance in a car some barely technical boss might say "well I want proof the radar is not going into the radio!!!!". You can tell him theory till you are blue in the face on the back of a ambulance but the only thing that's gonna shut that guy up is a graph!! Big companies don't have theory based risk takers! If you try trying to use mixers or making some attachment the totally non technical guy is gonna ask "well how did you calibrate that? what is the confidence interval on the measurement? what is temperature effect"? You might wanna say jack shit but that is NOT a valid answer in a accredited environment. Hell, they will get pissed off if the equipment is from a different manufacturer and that you need to connect two boxes with cables. How do we know that cable is good? I don't think you ever deal with a pain in the ass before. |
