When we developed and introduced these products 25 years ago, we were really enthusiastic about a new tool that would tell us virtually anything about the most complex RF signals. They were significantly more precise than the spectrum analyzers of the time, especially on time-varying signals or those with complex modulation. Looking back, however, I remember the RF engineers who were developing VSAs also had power meters and power sensors on their benches, and used them frequently. Those power meters and sensors were the benchmarks for our nascent VSAs, and the new analyzers would never have achieved such exceptional accuracy without them.
When was it decided to try to design the product? We announced our 6.
After the success of the 6. That being said, our typical development time ranges from 1. Who came up with the idea for it? The vision of our company is often driven by our CEO, Dr. What was the development timeline, from first concept to introduction?
However, the idea for a high-performance RF product was conceived 2. What were the critical milestones in the design? Fitting high-performance RF components in the small form factor of PXI is always challenging and was definitely a key milestone.
Some of the others were: Designing oscillators with the low jitter requirements of the in such a small space is always a challenge. Given that the is a three-stage superhet architecture, all three local oscillators on the contribute to the overall phase noise specification of the Figuring out the design, testing, and manufacturing of the was key to this project.
The NI design team came up with innovative group-delay calibration techniques applied to the entire MHz bandwidth of the instrument. Were there any surprises in the course of design? How were they dealt with?
In addition to the challenges discussed above, heat dissipation in the small form factor of a PXI chassis was particularly challenging.
The design team came up with innovative shielding and heat dissipation techniques to account for the heat generated by the product.
The calibration over varieties of temperatures also helps keep the instrument accurate over a wide temperature range. What was the market reaction to the introduction? The was extremely well received by the market. We have many customers, such as ST Ericsson, who are realizing the cost, speed, and accuracy benefits of the Given the success of theNI will continue on high-performance analyzers.
NI will continue providing IP and instruments with an open programmable FPGA giving customers the flexibility to completely customer their high-performance instruments.If you do not remember your password, enter the e-mail address you used to register, it will be sent a new password, you will be able to change it at your next log-in.
We can supply the Agilent HP EA RF Signal Generator. We have thousands of model numbers in stock. We calibrate, rent and repair test equipment. The final stage in a RF front end before the antenna is usually a power amplifier (PA).
The PA creates a large output power from the small input power signal to be sent out to the antenna. Many issues arise in power amplifiers due to their distortion, large power consumption, and high cost of these devices.
Because of these issues. of traditional lab -grade spectrum analyzers at a fraction of the cost, size, weight and power consumption and is also designed for distributed deployment.
