5.6.5. Power Ramp Tool
The Power Ramp Tool determines the minimum power to activate a tag and
can help determine tag quality. This activation power level can help
determine the read range at various attenuation levels and, for AVI
applications, can help determine the "read-zone" or an antenna pattern.
The tool starts by configuring the reader to start transmitting at a low
attenuation level (usually 0.1 dBm) and increments the level until it
observes a response from the tag. The transmitter is turned off and the
minimum value to activate the tag for a given antenna and distance is
reported.
The Power Ramp controls include:
h Increment Rate (ms) – Time tool stays at a particular power level
before incrementing to the next power level.
h Initial Attenuation Level (dBm) – Starting attenuation level.
h Attenuation Decrement (dBm) – Step-size for attenuation
decrement.
h Antennas section allows you to select which antenna(s) to test with.
h Filter section allows you to apply a filter to only look for a particular tag.
