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.

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.

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 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.

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.

We are measuring eye diagrams of the eyes of high-speed PAM signaling. It's the primary reference for measuring the quality of our transmitted signal, so we're using it to validate that we made the correct chip and that our circuits are working as expected.

They're 100-gigabit per second PAM-4 signals and they're enabling the data center and high-speed wireless connectivity. We're utilizing the full bandwidth of the product.

For us, the solution is targeting 5G, high-speed serial, and embedded systems. For example, in 5G, we're using the optical, we're measuring T.Q, or some fancy optical output. And for the embedded system, we're measuring the electrical performance, usually over some sort of backplane. 

We use it to debug our system designs and see the signals on the physical side, especially on Internet IPs.

We're using the 1 GHz oscilloscope.

It's a high-speed serial design. We are using it to debug the signals of the high speed serial. It is throwing it around 25 gigs. We also use it to measure all of our reference clock frequencies.

We are using all board differential and single-ended channels to send signals. The product is used in data center applications.

I use Keysight products on and off depending on the customers that I work with. If they have Keysight equipment, then I will use it.

My primary use case is measurement equipment. I work on high-speed designs, With those, there is a whole array of Keysight equipment, but again, when we go as in-house consulting engineers, we work with the tools that the customers have.

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.

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.

I automate these devices for the other persons to use and take measurements. Our current model is a VNA machine.

I'm using Keysight VNA, Oscilloscopes, and Spectrum Analyzer. The oscilloscope is mostly used for Keysight because they have a very high resolution and very high memory digs. They also can capture the signal reading at a very high signal read. We regularly go to 100 gigabits so we can capture a lot of signal for Keysight.

I'm currently using the 86100D and I've used the 86100C as well. The "D" is the most recent one so I'm using that right now.

We use it for test and validation. We want to verify measurements in our lab to make sure for our current products that everything looks optimal, as per the specs. We make sure that whatever we're looking at, the scope can give us all the features to validate that product. We use it for Tx jitter measurements, compliance measurements for ten-gig SFP+, QSFP28, and QSFP+. That's where it really is helpful, to do compliance measurements that actually correlate with the spec.

We are utilizing the full bandwidth. We use it for all speeds greater than ten gig.

We're using the N5227A 67-gigahertz analyzer for signal integrity applications, the passive components.

The solution is targeting the high-speed application space for us. Since we design components, primarily connectors, it needs to be high-speed to meet all the demands a standard connector company would need to meet, like a Tyco or Amphenol.

We are measuring standard step signals, full signals. We are utilizing the full bandwidth of the product.

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.

Our primary use case is the IBIS-AMI Model.

We are using the Advanced Design System (ADS). We are doing the IBIS model for our customers. We develop our service, then our customer will evaluate it and comeback after checking whether our service has good correlation.

The application space that we target is high-speed serial, like PCIe, SAS, or SATA, which are all the industry standard. We develop it and deliver it to our customer.

We use them for experimental measurements.

We are using it to do research. We're currently doing optimal links research.

We are measuring PAM-4 signals with it.

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.

We are using Keysight for characterization.

The signals that I'm evaluating are basic analog signals for hard disk drives.

We are using Keysight Oscilloscopes and software for assimilations.
