The E-Field Evaluation Board (EFIELDEV) is designed to demonstrate E-field coupling under various conditions on a Printed Circuit Board (PCB). These experiments will help system designers understand the impact PCB layout techniques have on controlling E-field noise in their design.

The E-Field Evaluation Board PCB supports measurement of capacitive trace-trace coupling, in 1-layer, 2-layer, and 3-layer experiments; in each experiment, Transmitter-to-Receiver PCB trace spacings are varied, to demonstrate how coupling changes with distance.

The 2-layer and 3-layer experiments use 1-plane and 2-planes of shielding to further reduce coupling. Additional measurements demonstrate fringing (non-line-of-sight) and via density effects.

Limited by Gain Bandwidth of the on-board Operational Amplifier buffer/amplifier [needs external 9V] with Gain=1 or 10, experiments are run with frequencies from 10 kHz to 10 MHz from a Function Generator, amplitude measured using an oscilloscope; this range of frequencies illustrates how capacitive coupling is not dependent on frequency.

The PCB has eight experiments, with up to 8 different Transmit-Receive trace-to-trace setups.

The Magnetic Field Evaluation Board (104-00138) is designed to demonstrate H-field coupling under various conditions. These experiments will help system designers understand the impact PCB layout techniques have on controlling magnetic coupling in their design.

The Magnetic Field Evaluation Board supports measurement of inductive (magnetic) trace-to-loop and loop-to-loop coupling, with and without shielding by planes.

Some experiments examine strong horizontal between layer loop-to-loop coupling, where shielding effects are easily demonstrated. Other experiments examine typical PCB trace configurations, where loop areas are much smaller and effects of distance are easily demonstrated.

Limited by Gain Bandwidth of the on-board common-base Gain=100 signal booster [needs 9V], experiments are run from 1 kHz to 10 MHz, to demonstrate how inductive coupling is dependent on frequency.

With 5V AC input [yielding 0.1 amp peak-to-peak into 50 ohm load], amplifier output amplitudes are .002V to 2 volts.

The MCP3909 3-Phase Energy Meter Reference Design is a fully functional Flash MCU based 3-phase energy meter. The meter comes populated with components for a 220V, 5(10)A system complete with plastic IEC compliant energy meter case. The case contains high voltage line and load screw terminals for direct connection to mains voltage or to energy meter calibration equipment.

There are over 100 serially accessible output registers containing power quantities, in Flash. For calibration, there are registers including offset, gain, phase, and LSB correction for all power and energy quantities, in Flash. All registers are accessible through RS-232 and USB.

The calibration and correction registers can easily be moved from Flash to EEPROM using a simple ‘store’ command for end user configurable write cycle times.

The analog conversion uses the wide dynamic range 16-bit ADCs MCP3909, which are sampled at 128 times per line cycle. The calculations are all interrupt driven to ensure ‘Zero-Blind’ measurements for all power quantities per line cycle.

The system also includes a Phase Lock Loop circuit for line cycle sample lock.

The system is easy to use, command driven, and offers ‘mode’ registers for features such as positive only energy accumulation mode or no-load threshold mode. A 64-bit wide active energy register is used for long term energy accumulation. Phase calibration for CT non-linearity correction is included.

In addition to the power calculation engine using MCP3909 + PIC18F2520, a second communications module is included with the system. The included communications module is the PIC18F4550 USB Interface Module, which allows for meter evaluation and calibration using the “3-Phase Energy Meter Software” running on Windows XP or Windows 2000. The PIC18F4550 USB interface module also includes an LCD for additional energy meter firmware design.
