Figure 2-20 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 2-20 shows the filter shapes associated with the P-Series
wideband power sensors.
Procedure
