Making Stimulus Response Measurements

12.Reconnect the DUT to the analyzer. Note that the units of the reference level have changed to dB, indicating that this is now a relative measurement.

Press Trace/View, More, Normalize, Norm Ref Posn to change the normalized reference position. Arrowheads at the left and right edges of the graticule mark the normalized reference position, or the position where 0 dB insertion loss (transmission measurements) or 0 dB return loss (reflection measurements) will normally reside. Using the knob results in a change in the position of the normalized trace, within the range of the graticule.

 

13.To measure the rejection of the filter 45 MHz above the center of the

 

bandpass, press Marker, 200, MHz (to ensure that the marker is in the

 

center of the signal), and then press Delta, 45, MHz. The marker

 

readout displays the rejection of the filter at 45 MHz above the

 

center of the bandpass. See Figure 2-4.

 

Because the default trace is comprised of 401 discrete points, the

NOTE

 

indicated marker frequency may differ slightly from the frequency that

 

you entered. Due to the horizontal resolution of the trace, the marker

 

frequency value will be rounded to within 0.25% of the span of the value

 

entered. If the analyzer is an ESA-E series with firmware revision

 

A.04.00 or later, the number of sweep points may be set to any value

 

between 101 and 8192.
