Figure 2-35 Bandwidth filter shapes
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
sharp cut- off filters used in the Low, Med and High settings. Figure 2- 35
shows the filter shapes associated with the P- Series wideband power
sensors.
