Precision Variable Attenuator
DiCon’s Precision Variable Attenuator is a TTL-driven
component which sets attenuation levels in the 0 to 30 dB
range with superior repeatability and absolute accuracy. The
attenuation level is set using a high-precision motor with either
the I
2
C standard interface or a proprietary Step-Up/Step-Down
interface.
