Keysight Oscilloscopes Reviews

We use Keysight VNA to make sure of our materials' performance and DKDF measurements.

It's mainly for 5G and high-speed, high-frequency systems. VNA can be used in multiple ways. Right now we are using it to characterize our materials. But in the future, we want to make some devices, like antennas or circuits, using our materials and measure them using VNA. It has a lot of capabilities.

For us, it's mainly RF signals. Typically, we measure about 40 gigahertz or so. We are not currently using the full bandwidth but we expect to in the future.

The measurements that the network and laser do are very important for us because DuPont is a materials company and we need to know the performance of our materials at high frequencies. This is the way to measure that, using the VNA.

We use it for high-speed signaling, including RF. Of course, 5G is catching up and in the future it is going to converge at a certain frequency range that will benefit both sides of the industry.

The signal we are measuring is primarily the internet signal through the data centers and switching routers. We are not directly measuring the RF signal, like for the 5G wireless. However, all the data from 5G is going through the backbone before translating into the digital signal, which requires much higher bandwidth to accommodate all the 5G signals.

We are definitely utilizing the full bandwidth.

The most important thing is to correlate with the simulation, and Keysight scopes have long been known for doing that pretty well.

I use it with connected devices, like IoT, in the lab to validate, verify, or design.

With this scope, we are measuring: Internet signals, media signals, PCIe, USB signals, and some other low-speed serial interfaces.

The DDR Utilities that I have used on the scope speed up my debugging process. Similarly, I use the serial decoder for the serial interfaces, which helps me debug my product quickly.

We are using it for R&D and production testing. We currently have a few models. We have a 26 gig with 32 ports. We also have 40 gig and 67 gig models.

I'm an SI engineer. We use Keysight equipment almost six hours everyday, making a lot of measurements.

Their software and hardware are integrated, so we don't have to spend a lot of time processing the data.

We use it mostly for experimental measurements.

The space we use it in is high-speed and some instances of 5G as well. But we use it mostly for high-speed serial links. We are mostly measuring signal integrity and S-parameters. We're not using full bandwidth yet. We're still at lower speeds, but very soon we may be using the full bandwidth.

We use it to support connected devices as well. I can't go into details, but it's part of the internet of things. In my company we are trying to create a connected world. That is one of our main goals. There are different products located in different places and we want them all to be connected. This can definitely be useful to design and to include them.

We have done some measurements and also correlated with simulation and we were able to obtain a good match, so that's a good indication of the accuracy.

We use this for testing our product and also for doing major maintenance, simulation correlation.

For example, we design a test for what we call our channel test vehicle. We have a simulation result according to our structure, such as a BGA footprint. Then we use the channel test vehicle, and test with Keysight VNA so we can compare the result with our simulation.

For us, the solution is targeting high-speed serial, like I/O ports, things like a 25-gigabit per second signaling array. We use it for a lot of I/O components and connector cable qualification. We utilize the full bandwidth.

It's very convenient because once we set up everything, we just queue our test plan and then are able to do whatever we want: embed with the key size and the PLOTS auto fix removal. And it has a good calibration kit. It's very convenient to use.

The user interface is very good, very graphical. It provides a lot of help in using and operating it.

Our primary use case is measuring PCIe and differential signals (CCIX).

We use a high-speed scope for measuring differential signal, which measures for electrical specifications. This is what our PCIe protocols are all about.

The product's functionality makes things easier for my partner, who is doing the PCIe design. He is able measure the product's usage and bit error rate.

Our lab has a 16-gigahertz scope and the 64-gigahertz scope. We have some other test equipment in our labs. We have an area of equipment in the lab that we use for high-speed measurements.

We use them for high-speed compliance measurements: electrical measurements of all the external interfaces, such as USB, display port HDMI, etc., which enable you to use your pen drives or connect your display. 

I personally run less of the measurement side now, I do more simulations, but we always correlate simulations with measurements and we need to get an accurate measurement and an accurate simulation to verify if our design works. Otherwise, all of these devices we build won't actually work in the customer's hand. Keysight is the main test equipment vendor, in our lab. We do have some other vendors but we almost exclusively run on Keysight these days.

Regarding the bandwidth, some of the scopes, like the 64, have a higher bandwidth than what we need with our current data rates, but otherwise, we typically use most of the bandwidth.

Every product that we sell goes through a regular set of testing. Keysight is our main test vendor so we're using all of their equipment for all high-speed measurements. We rely on the data and we make our design calls, risk-assessment, all based on the measurements that we take with the Keysight equipment. Those need to be accurate, otherwise our design decisions would vary from what the end customer would see in reality.
