What is our primary use case?
We use a 40-gigahertz network analyzer to look at in-session loss or retention loss at 28 gigahertz. For us, the solution targets high-speed switches and routers, high-speed PCB. We are measuring 400-gig Ethernet. We're definitely using the full bandwidth of the product.
How has it helped my organization?
We need the results to be repeatable. By using the Keysight network analyzer, we get pretty reliable results. We like it.
What is most valuable?
Also, the PLTS is pretty convenient.
What needs improvement?
Some of the models have only two ports. It takes much longer to use a two-port. If they had a four-port, it would be much better.
For how long have I used the solution?
More than five years.
How are customer service and technical support?
Technical support is pretty responsive.
What's my experience with pricing, setup cost, and licensing?
Keysight is on the high side. If they could make the price lower without sacrificing the quality that would be great.
Which other solutions did I evaluate?
We looked Tektronix, Keysight, and a few others. The reasons we went with Keysight are accuracy, reliability, and ease of use.
What other advice do I have?
Create a shortlist and have a demo with each of them. Try each one. Once you do some trials, experiments, you will know what you want to choose. There are several things we look at: One is the accuracy, the second is the reliability of the equipment, and the third is how easy it is to use.
There is no learning curve because I've been using it for so long and it's pretty simple.
The solution is field-upgradable. We may add more functionality to the PLTS.
I would rate the product at eight out of ten. It's pretty easy to use, pretty reliable. It doesn't break, so it can work in a very harsh environment. But for a lot of additional functionality, we need to pay extra. So that is where there is room for improvement.
