Learning to Make Transmission Measurements

Measuring Passband Flatness or Ripple.

Passband ﬂatness (or ripple) is the variation in insertion loss over a speciﬁed portion of the passband.

Continue with the following steps to measure passband ﬂatness or ripple.

1.Press Save/Recall (if necessary, scroll to the desired ﬁle using the and front panel keys). Press RECALL STATE to recall the error-corrected transmission measurement that has no markers engaged.

2.Press Marker and turn the front panel knob to move marker 1 to the left edge of the passband.

3. Press Δ MODE MENU Δ REF = 1 to change the marker 1 position to the delta reference point.

4.Press MARKER 2 and turn the front panel knob to move marker 2 to the right edge of the passband.

5.Press Marker Fctn MARKER MODE MENU . Toggle MKR STATS on OFF to ON.

The analyzer calculates the mean, standard deviation, and peak-to-peak variation between the Δ reference marker and the active marker, and lists the results in the upper-right corner of the display. The passband ripple is automatically shown as the peak-to-peak variation between the markers.
