Test equipment
Serial vector format (SVF)
Semiconductors; Test equipment
SVF is the media for exchanging descriptions of high-level IEEE 1149.1 bus operations. In general, IEEE 1149.1 bus operations consist of scan operations and movements between different stable states ...
Standing wave ratio (SWR)
Semiconductors; Test equipment
Sometimes called voltage standing wave ratio. Describes the deviation of an impedance from the characteristic impedance Z. The SWR is calculated from the reflection coefficient r. SWR = (1 +
Solid state relay (SSR)
Semiconductors; Test equipment
An electrical switching device, which uses a semiconductor to block or conduct current flow in a circuit with respect to the status of a control signal.
Standard test and programming language (STAPL)
Semiconductors; Test equipment
Pioneered by Xilinx and adapted by other device vendors as a device programming language
Test access mechanism (TAM)
Semiconductors; Test equipment
The connectivity and protocol structure used to access an instrument. For IEEE Std 1500, a defined TAM exists.
Peta (T)
Semiconductors; Test equipment
Representing one thousand million million, or 1,000,000,000,000,000. Peta is 10 to the 15th power.
