The V-Pole™ is designed to safely optimize performance of MicroAcoustic's BAT™ transducers when operating as sources. In operation, the V-Pole™ accepts as input any user-supplied drive signal and safely superimposes this upon one of two switch-selectable, high-voltage polarization settings (high and low). The low polarization setting is typically used in conjunction with high-amplitude bipolar drive signals (e.g., tonebursts, chirps and CW signals). The high polarization setting is used to maximize transducer bandwidth for use with low-amplitude bipolar drive signals or with negative-going monopolar drive signals (such as that obtained from a standard ultrasonic spike-generator). An important feature of the V-Pole™ is its voltage-limiting output, which ensures that the sum of drive and polarization voltages does not exceed the transducer’s recommended voltage rating. The V-Pole™ is compact and is available in either a single-channel or dual-channel version. The dual-channel V-Pole™ is particularly useful when trying to independently drive two elements of a dual-element BAT® transducer (such as
