Making Stimulus Response Measurements

Figure 2-9 Tracking Generator Output Power Activated in Log Sweep

10.Put the sweep time of the analyzer into stimulus response auto coupled mode by pressing Sweep, then Swp Coupling (SR). See Figure 2-9. Auto coupled sweep times are usually much faster for stimulus response measurements than they are for spectrum analyzer (SA) measurements. Adjust the reference level if necessary to place the signal on screen.

11.To make a transmission measurement accurately, the frequency

 

response of the test system must be known. Normalization is used to

 

eliminate this error from the measurement. To measure the

 

frequency response of the test system, connect the cable (but not the

 

DUT) from the tracking generator output to the analyzer input.

 

Press Trace/View, More, Normalize, Store Ref (13), Normalize (On).

 

This will activate the trace 1 minus trace 3 function and display the

 

results in trace 1. The normalized trace or flat line represents 0 dB

 

return loss. Normalization occurs each sweep.

 

Since the calibration trace is stored in trace 3, changing trace 3 to

NOTE

 

Clear Write, Max Hold, or Min Hold will invalidate the normalization.

 

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. Refer to Figure 2-10.

 

13.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. Using

 

the knob results in a change in the position of the normalized trace,

 

within the range of the graticule. Refer to Figure 2-10.
