Keysight Oscilloscopes Reviews

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.

They are one of the top name in the industry. When it comes to grabbing precise technical data, having an ecosystem of logging it correctly and working with the diagnostics, they are probably the industry leaders in the field.

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.

We measure the skewing of the design and system with a simple click of the button.

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

We are measuring PAM-4 signals with it.

We generate a waveform from the AWG. We using the scope to sample the waveform, then do offline processing.

The Keysight Ecal feature has made it very easy for me to do calibrations.

While the user interface is pretty good, going forward, we would like to upgrade it. It needs better calibration features.

We are using this product to support connected devices for IoT development, but we need more automation.

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 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.

Before silicon came back, our customers' performance was affected. Using these tools, we are able to deliver performance to our customers. 

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.

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.
