So far I have been concentrating on the Atmel Cortex M0+ ATM processors. ARM processors pack a lot of computing power at very low cost. The ARM® processors look very interesting for systems that require more processing power, and I have started working with them. I also like Atmel processors, especially the MegaAVR® family.
Microchip really changed the world in the early to mid 1990’s with their powerful and low cost microcontrollers combined with development systems even students and hobbyists could afford. In recent years I have primarily used Microchip PIC® and Atmel AVR® processors. I have designed microcontroller based systems based on about a dozen different microcontrollers over the years, including the 6800, Z.
Even in small quantities, it is possible to buy a microcontroller with the power of the Apollo Guidance computers for about $1. I wouldn’t be surprised if your next toaster has one. Microcontrollers are under the covers just about everywhere. The same technology advancements that have brought down the cost and increased the power of PCs have also happened in the microcontroller world. Software on the microcontroller allows it to monitor inputs, make decisions, and control outputs. My real love in electronics is embedded systems, where small microcontrollers interface to the outside world. Occasionally I will commercialize my designs and sell them on my other website for Unified Microsystems. I find it relaxing to play around with electronics on evenings when the day job schedule involves mostly meeting and management tasks. I still like to play with circuits and design electronic systems for use in my other hobbies. When compliance testing is due, first check your design with the DSA815-TG and our optional near-field probes.Electronics was an interest and hobby of mine before it became a career. Other options are available, including an EMI filter and quasi-peak detector kit.
The DSA815-TG includes plenty of useful standard capabilities - including AM/FM demodulation, and a signal preamp. The DSA815-TG can also distinguish between signals with a frequency difference as little as 100Hz. The DSA815-TG is capable of measuring very small signals using a digital IF filter, which allows smaller bandwidth settings and reduces the visible noise levels. Ideal for benchtop or field applications, it is in use in RF and wireless test and production situations around the world. It features a unique widescreen LCD, compact desktop design and intuitive operation. Rigol's DSA815-TG spectrum analyzer has redefined the 1.5GHz product category by breaking both price and performance barriers, adding a Tracking Generator so you can do frequency scans easily! The DSA815-TG gives immediate access to RF spectrum analysis and scanning.
