Frequency Range

Frequency range is the span of frequencies you specify for making a device measurement.

How to set Frequency Range

You can also make these settings and more from the Sweep Type dialog.

See the frequency ranges of all analyzer models.

Using front-panel
hardkey [softkey] buttons

Using Menus

Press Frequency

Click Stimulus
then Frequency

Frequency Start/Stop - Center/Span - Step dialog box help

Either of the following pairs of settings determine the frequency range. The last value that you enter determines the X-Axis labels. For example, if you enter the Start and Span values, the X-Axis will show Center and Span labels.

Start /Stop - Specifies the beginning and end frequency of the swept measurement range.

Center /Span - Specifies the value at the center and frequency range.

Either of the following settings determine the number of evenly-spaced data points across the frequency range.

Points - Specifies the number of evenly-spaced data points across the frequency range. Learn more about Data Points.

Step - Available ONLY in Linear sweep type. Specifies the frequency step size between evenly-spaced data points. Changes to this setting will cause the Points setting to adjust to the closest integer. Any 'remainder' will adjust either the Stop value or Span value depending on which is displayed on the X-Axis label.

Zoom

Zoom allows you to easily change the start and stop frequencies or start and stop power levels in a power sweep.

Zoom operates on the Active Trace and all traces in the same channel as the active trace, regardless of the window in which they appear.

How to Zoom in a measurement window

Left-click the mouse or use a finger, then drag across a portion of a trace.
Release the mouse or lift the finger and the following menu appears:
Select from the following:

Zoom - changes the channel stimulus settings to the left and right border values of the Zoom selection
Zoom xy - changes the channel stimulus settings as above. In addition, the Y-axis scale of the active trace changes to the approximate scale of the Zoom selection.
Zoom Full Out - changes the channel stimulus settings to the full span of the current calibration. If no calibration is ON, then the stimulus settings are changed to the full span of the PNA model.

Notes

The stimulus settings are changed for ALL traces in the active channel, regardless of the window in which they appear.
If markers are in the selected area, they remain in place.
If markers are in the unselected area, they are moved to the right or left edge of the new span. When Zoom Full Out is selected, the markers are moved back to their original location.

Zoom is NOT available for the following:

CW Frequencies

Measurements with a CW Time sweep or Power sweep are made at a single frequency rather than over a range of frequencies.

How to set CW Frequency
Set Sweep Type to CW Time or Power. You can also set CW frequency from the Sweep Type dialog box.
Using front-panel hardkey [softkey] buttons	Using Menus
Press Freq then [CW]	Click Stimulus then Frequency then CW Frequency

CW Frequency dialog box help

CW Type a value and the first letter of the suffix (k,m,or g) or use the up and down arrows to select any value within the range of the PNA.

Frequency Resolution

The resolution for setting frequency is 1 Hz.

Frequency Band Crossings

The frequency range of the PNA covers several internal frequency bands. The higher the frequency range of the PNA, the larger the number of bands. The source power to your DUT turns off as the stimulus frequency is swept through these band crossings. To learn more, see Power ON and OFF during Sweep and Retrace.

The listed frequencies in the following tables are the stop frequency of the specified band, and the start frequency of the following band.

You can download a PNA Band Structure Readout utility that lists the band crossings for your PNA.

Frequency band crossings are different for the following models:
