Bandwidth analysis

The Agilent 4294A provides a trace bandwidth analysis function and allows you to analyze 
the active trace’s bandwidth. Use the following command to turn ON this function.

•

“WIDT” on page  461

NOTE

The trace bandwidth analysis function is available when the marker function is ON.

The applicable range for bandwidth search is the same as the range searched by the marker.

When the trace bandwidth analysis function is ON, you can search to the right and left of 
the current marker position for cutoff points. When the search is complete, submarkers 2, 
3, and 1 will appear, respectively, at the leftmost and rightmost cutoff points and at the 
center midway between the two cutoff points.

You can use the trace bandwidth analysis function to analyze the following parameters:

•

Bandwidth  (

Width

 in Figure 7-2)

•

Sweep Parameter Value at the Center between the Two Cutoff Points (

Center

 in Figure 

7-2)

•

Q  value  (=

Center

/

Width

)

•

Marker-specified Measurement Parameter Values (Note, however, that one of the two 
different sets of parameter values appears depending on which 

Δ

 marker is ON. When 

the tracking 

Δ

 marker is ON, the marker-specified parameter values will appear. When 

the fixed 

Δ

 marker is ON, those values, obtained by subtracting the fixed 

Δ

 marker-specified values from the marker-specified values, will appear.)

NOTE

Normally, trace bandwidth analysis is made when the marker searches for peaks. 
Therefore, the above values appear to the right of “Peak:” on the Agilent 4294A display. 
However, if the marker is not positioned at any of the peaks, the above values do not 
represent parameter values obtained at a peak.

•

Value Obtained by Subtracting the Value at the Center of the Sweep Range from the 
Sweep Parameter Value at the Leftmost Cutoff Point (sweep parameter value when the 
fixed 

Δ

 marker is ON) (

Δ

L.F

 in Figure 7-2)

•

Value Obtained by Subtracting the Value at the Center of the Sweep Range from the 
Sweep Parameter Value at the Rightmost Cutoff Point (sweep parameter value when 
the fixed 

Δ

 marker is ON) (

Δ

R.F

 in Figure 7-2)

Use the following command to selects the method to set a cutoff point in the trace 
bandwidth analysis function.

•

“WIDVTYPE” on page  462

If the free cutoff value setting is selected with the “WIDVTYPE” command, use the 
following commands to specify measurement parameters (Cutoff Value in Figure 7-2) at 
cutoff points:

•

“WIDFVAL” on page  460

NOTE

When you wish to use the “WIDFVAL” command to specify measurement parameters at 
cutoff points and when the 

Δ

 marker is ON, you must remember that the value obtained by 

subtracting the value you enter from the 

Δ

 marker-specified value will be specified as the 

measurement parameter value at the cutoff point, as shown in Figure 7-2.
