Frequency Range
Frequency range is the span of frequencies you specify for making a
device measurement.
See other 'Setup
Measurements' topics
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 Hardkey/SoftTab/Softkey |
Using a mouse |
Press Freq> Main >
Start,
Stop, Center, or Span. Enter desired frequency
value.
Note:
When number of ports is greater than 12, changing sweep parameters
takes long time due to the calculation for collection. In order
to avoid this, the Sweep Type
dialog box is displayed instead of entry. |
Right click on the X-axis label or stimulus
range area under grid line. Click on . |
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.
Note:
The start frequency at preset may not be the minimum value in
full range.
Note: The maximum frequency
of M9808A, P50x8A is 54 GHz. However, the specification is applied
up to 53 GHz. (The maximum frequency is 53 GHz for the units shipped
with the A.13.70 and below. Re-calibration is required for upgrade.)
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 VNA 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 |
Using Hardkey/SoftTab/Softkey |
Using a mouse |
Set Sweep
Type to CW Time or Power
Sweep. Press Freq
> Main > CW. - Enter desired CW frequency.
|
Set
Sweep Type to CW Time or Power
Sweep. Right
click on the stimulus range area under grid box. Click on . |
|
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 VNA. |
Frequency Resolution
The resolution for setting frequency is 1 Hz.
Frequency
Band Crossings
The frequency range of the VNA covers
several internal frequency bands. The higher the frequency range of the
VNA, 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 VNA
Band Structure Readout utility that lists the band
crossings for your VNA.
Frequency band crossings are different
for the following models:
