When video bandwidth is set to Off, it removes all digital signal
conditioning. This provides approximately 3 dB roll off at the maximum
sensor’s bandwidth and is best suited for accurate trace capture,
minimizing overshoot, and removing any ringing effects caused by the

shows the filter shapes associated with the P- Series wideband power
sensors.
