Circulators
-
The most common application of a circulator is as a duplexer, allowing the transmitter and receiver in a radio or radar unit to share a common antenna. Energy is transferred from the RF Source to the antenna during transmit, and from the antenna to the receiver during the receive cycle. In each case the circulator functions to isolate the inactive port from the propagated signal. Most importantly, the transmitter output is not passed to the receiver input, preventing the high transmitter power from damaging the sensitive receiver input circuits.

Embedded Transceivers
-
Embedded transceivers are chip-sized components based on 850 nm VCSELs and offer bandwidth up to 300 Gbps for short reach applications (<300 m). These transceivers can be soldered or socketed to a printed circuit board and are well suited for small, compact systems requiring high I/O density, low power, and small space. Many of these transceivers have been qualified to operate in harsh environments, such as the ones found in space, and aerospace and defense applications.

ESD Protection
-
Protection against electrostatic discharges (ESD) is part of EMC Immunity (Electro Magnetic Compatibility) requirements. It is the ability for equipment to properly operate in its electromagnetic environment by limiting the reception of electromagnetic energy that may cause physical damage. ESD can be either conducted under the form of a transient voltage or can be radiated due to its fast rising time: powerful harmonics will generate erratic behavior by the application by coupling with other signals. Printed circuit boards must be protected against the effects of electrostatic discharge.

PXI 5A Fault Insertion Switch 10-Channel
40-196-001
Fault Insertion Unit
The 40-196 is a 10 Channel 5A Fault Insertion Switch, primarily designed for the simulation of fault conditions in automotive & avionics applications involving the reliability testing of safety critical controllers. It is designed to be able to insert different fault conditions between the test fixture and the equipment under test: Open-Circuit, Short-Circuit between signal pairs, Short-Circuit between signal pairs and user applied fault conditions e.g. Power or GND. Shorting relays on each channel enable UUT signals to be subjected to external user applied fault conditions or to be shorted to the adjacent signal in the same channel. Relays in line with the signal allow open circuit conditions to be simulated on either side or both sides of a channel signal pair. The switching topology of the 40-196 allows channels to be interconnected so that complex fault insertion systems can be constructed.
