NEW Non-Invasive Measurement Information
VRTS3 Distributed System Demo Board V1.0
The board contains eight individual circuit sections as identified in the table below. These circuits are typical in most distributed systems providing an excellent test bed for demonstrating non-invasive, in-system measurement, optimization and troubleshooting techniques. Table 1 Circuit Sections on the VRTS3 Board

Section Function
POL 5V USB input to 3.3V 2.8MHz switching regulator
REF03 2.5V low noise voltage reference
OPAMP 245MHz Bandwidth unity gain opamp buffer
LDO LD1086 voltage regulator 5V USB input to 3.3V output
CLOCKS/BUFFERS 10MHz and 125MHz clocks
CALIBRATION Short-Open-Load and 1 Ohm calibration ports
PLANES & CAPS Parallel tantalum and ceramic capacitor on a small PCB plane
MICROSTRIPS 50Ω microstrips with precision aberrations - one with a
ground void
