Datasgeet?
Let me know your email, please.😀
Wow!
The minimum output power is 100W from 2GHz to 18GHz. Contact me (zhaohao@ceyear.com) for the typical output power.
That cable has some gain at 110 GHz!
Actually, the signal generator is unlevel and the ALC (Automatic Level Control) loop is not working at that time. The rising internal temperature led to that but I didn't notice it. The actual output level is greater than the declared 2dBm.
Looks great!👍
Can you let know more about the other 110GHz VNA structure?

I shared this Video to multiple antenna engineers in Bangalore.
how much cost that PM? I haven't seen it @ your website
Dear sir, Please email me zhaohao@ceyear.com!
There is a protective film on the screen.😇
I don't even dare to check the price for these instruments ;) Interesting video though.
These dedicated devices are indeed expensive, but useful for R&D purposes. 😁

We know THz (Terahertz) is one of the top ten leading technologies, that can change the future world. It can be widely used in Biomedical & Biochemical Science, 6G Communication, high-resolution Radar, Security Check and 3-D Material Imaging areas.

Is it possible to detect X band radar with this analyzer ?
Hi, the current directional antenna cannot support up to X band. We have other solutions. Email me zhaohao@ceyear.com
Of course, the tester can work as a FM Radio receiver and we can listen to the radio using it. 😀
very good video
The declared rise/fall time of Ceyear 1466 series signal generator is less than 10ns. The actual typical value can be less than 5ns. But the 87234 series USB peak/average power sensor has a 30MHz bandwidth and its rise/fall time is limited. So the measured rise/fall time for this amplifier is limited to 13 or 14 ns. The actual value will be definitely lower.

How to voice control your test instruments? Let's take a look.
1. The RF power combination efficiency can be up to 90%. You may know we use Space Combination Technology to get a higher power. 2. For the total system’s power conversion efficiency, the efficiency is around 25%. You know the narrow/broad frequency band, the output power level, the different amplifier circuits, the cooling solution will all affect the total efficiency. We provide different power supply solution for different amplifiers. Two phase or three phase electricity power supply will be provided accordingly.
Ceyear amplifier uses multiple patented Space Power Combination technologies. It features wide frequency band, accurate displayed output power, higher frequencies, and higher power. Here are two customized solutions of 4GHz-8GHz 1200W and 6GHz-18GHz 600W amplifier systems.
how much did you spend for the entire setup?
Hi, great question! But it is hard for me to give a definite answer. The required time highly depends on the natural environment, electromagnetic environment, professional ability of the users, the DF height, the walkie-talkie's power and many other factors. The simple DF system in the video is one-node solution. And it usually needs to be placed in two places to get two direction lines' crossing point. And a handheld directional antenna is often used to approach the walkie-talkie. So, it usually needs tens of minutes find the illegal signals. This system can be mounted on a vehicle to shorten the time. Of course, a DF network with several DF systems can be configured to make the geolocation in real time with smaller potential area. It can further shorten the time. Contact me zhaohao@ceyear.com if you have more questions.
@@hawldydemolab949 device price?
Sample Dimension : rectangular pellets with exact dimensions as follows Length : 22.90 mm Width: 10.50mm Thickness: Less than 5.00 mm(how can i make this dimensions for VNA measurements)
Such a great question! As we know, the waveguide fixture (the Waveguide calibration kit) has different size and can work under certain frequency band. The sample size is dependent on the waveguide size or the frequency band you want to focus. If the sample is solid, you have to use the accurate machining device to make it a cuboid. If the sample is powder, you have to mix the powder with wax to make it solid and then use the machining device to make it a cuboid.
I really wonder how such electronics are designed internally.
