NovaSource RF Signal Sources

NovaSource is easy-to-use with programmable, nonvolatile memory and built-in synthesizer functions, including software-controlled attenuation of the buffered RF output and an internal reference signal. NovaSource family of products spans from 45 MHz to 5.875 GHz and offers tuning resolutions as fine as 1 kHz.

Molex Connectors - Interconnect Solutions

"Never Mix Electrical and Mechanical Connections" (probably from tektronix) this is a rule, more so for power connectors. Strain relief prevents mechanical stress from reaching the connector joints/spring metal. The wire terminations are also cushioned by strain relief.

The PCB and Product Engineering should ensure that the mechanical stress or load is not a job/function/role of the connector. At higher currents a small contact resistance can generate a lot of heat, worsening the contact further, similar to thermal runaway of Power Transistors.

Hardware design of digital, analog and microprocessor based circuitry. Circuits containing programmable logic or even ASIC's can be developed.

EMAC - Semicustom Embedded Engineering

Semi-Custom Development

There is no need to reinvent the wheel. Our off- the-shelf hardware has been fully field tested and development software has already been written.

Custom Product Design

Only your desired features are provided, costs are reduced. The required features, functions, and options can be placed on one printed circuit card, reducing costs.

Custom Design and Manufacture

Printed Circuit Boards, Hardware and Software, Control/Display panels. They supply and service, from concept to manufacturing.

The RAD Remote Access Device

RADical new device that provides serial terminal access to a remote host via a keypad and an LCD.

The great thing about the RAD is you can use whatever host you're comfortable with, from PICs to PCs, as long as it has a serial port (RS232/422/485), you're set. No programming of the RAD is necessary, just simply send it ASCII data and it displays characters on the LCD. Enter data from the keypad and ASCII characters are returned to the host.
