Rohde & Schwarz Oscilloscopes Reviews

I'm very much in the power integrity field. I spend a lot of time working for a major semi-conductor manufacturer doing silicon validation.

Our end product has to pass all the various FCC compliance tests, which is sort of the field of expertise that I have. For a customer to build a product with a switching mode power supply in it and be able to provide some degree of certification or comfort, they have to pass the compliance test which permits them to sell into the marketplace. That has always been an emphasis of mine, when I'm doing application engineering for a semiconductor company. They're selling to a company which integrates a switching mode device into their product. For them to sell that product, they have to jump through hoops, meeting a bunch of compliance tests that the FCC or European agencies establish. Once they pass, they are certified in their lab to sell. Then, I try and provide a lot of leading advice on how they can incorporate that noise generating device into a product with a high degree of likelihood that they will pass those tests.

We are doing an investigation of the interface between audio power amplifiers and loudspeakers, including the speaker wiring that provides the interconnect.

The Rohde & Schwarz gear that I use is because it's so sensitive. I'm always looking for things way down into the noise floor as part of the electromagnetic compliance work that I do.

We are using their VNA for our RFSoC PCB design guideline and EVBs.

The application targets on 5G and high speed transceiver applications. We care much about the noise floor and crosstalk. With this machine, it's easier for us to debug or clarify where the noise source could be because of its accuracy. 

For the RF application, we care much about the crosstalk on our device and PCBs. Generally, what we can do with the other vendor's product is four-port measurement. It's a bit complicated for us and time consuming to combine all the crosstalk measurement together in a  unified model. However, with this VNA, it is much easier because of its eight ports configuration. 

It's very stable because everything is done at the same time. This means within the test condition environment, everything is the same. This has increased accuracy and dramatically saved a lot of our time.

We can do more experiments with this product than using other VNAs which have less ports.

I'm using the VNA for basic measurements, debugging, and troubleshooting in the automotive industry.

The application space that we are using the solution to target is all types applications: high-speed digital, high-speed serial, channel evaluation, cables, measuring cables, and measuring connectors.

I am measuring high-speed and low-speed signals.

The product is quite reliable and straightforward to use. Typically, there are no households that we have to set up.

Our primary use case is audio measurements, as well as current measurements.

We use the UPV Audio Analyzer mostly, not the scope. We use Bluetooth in our product. We are measuring currents for enabling Bluetooth.

We can't measure our dynamic current with oscilloscopes. We can only use an Audio Analyzer, because of the low noise floor. Thus, it provides information that we couldn't get otherwise.

Our primary use case is telecom. I use a couple of their models.

The application space that we are using the solution to target is 5G and another proprietary connectivity solution for digital health and autonomous driving.

Essentially, we measure the signal to noise issue, various EVM, and other wireless performance.

• It is easy to connect with.
• It's accurate.
• It's reliable.
• It hardly fails.

I used it for board design, EMC/EMI measurements, EMC/EMI testing, and for RF measurements. I used it to test some parameters in phased array antennas, to do testing of far fields. I was measuring signals up to 15 gigahertz, and for EMI testing according to the FCC.

I used it to support connected devices for IoT development.

I used the full bandwidth of the product.

I used it almost every day as a lab testing and measurement unit. It was a mandatory instrument for doing my job.

The primary use case is debugging, prototyping, and validating the check site and design, e.g., the circuitry and hosts. We have several testing stages to go through before production.

We have a lot of different models that we are using in the lab. We work with the highest view scopes and protocol analyzers, like PCIe, SAS, and SATA. We use them a lot. The PCIe analyzers, like PAM, have full size testing equipment in our labs.

We are the server producers. We touch every corner: high-tech. electronic, electrical, down to the mechanical, materials, and performance. We provide the backbone to support the words - Internet connection.

• Accuracy
• Console/GUI
• Zoomable things
• Remote access

I'm using the EMC Receiver for compliance testing, EMC. For us, the product is targeting embedded systems, predominantly, and I have multiple antennas on the same board: Cell mode, GPS, Bluetooth. Keeping all those separate and identifying them is a major part of it.

We are also using this product to support connected devices for IoT development.

We utilize the full bandwidth.

Repeatability is the main thing: Being able to go back to the lab and test get the same results. I know what to fix and how much to fix and when to stop.
