3. Basic Settings

3.1. FREQ

Set the frequency parameter of analyzer. The analyzer sweeps within a specified range, and the sweep will start once you change this parameter. The frequency range of current channel can be expressed by either of two groups of paramenters: Start Frequency/Stop Frequency （ f

（ f

center/fspan

） . If any one of them is adjusted, other three parameters will be changed

start/fstop

accordingly to ensure their coupling relationship.

3.2. Center Frequency

Enable the center frequency function, to allow a frequency displays in center be selected. When pressed, the frequency mode is switched to Center Frequency/Span for input. In this mode, parameters you specified are always shown at the lower right and left side of the display grid.

Key points:

 The start and stop frequencies vary with the center frequency when span is constant.  Changing the center frequency horizontally shifts the current sweep channel and the

adjustment is limited by the specified range in datasheet.

 In the Zero Span mode, start frequency, stop frequency and center frequency are always

equal.

 User can modify this parameter by numeric keys, knob and arrow keys.

3.3. Start Freq

Set the start frequency of current channel, displays at the left scale. When pressed, the frequency mode is switched to Start Frequency/Stop Frequency for input. In this mode, parameters you specified are always shown at the lower left and right side of the grid.

Key points:

 The span and center frequency are changed automatically according to the start frequency.

The change of the span would have influence on other system parameters. For more details, please refer to “Span”.

 In Zero Span mode, the start frequency, stop frequency and center frequency are always

equal.

 You can modify this parameter using the numeric keys, knob, or arrow keys. Table 2-2 Start Frequency

3.4. Stop Freq

Set the stop frequency of current channel, displays at the right scale. When pressed, the frequency mode is switched to Start Frequency/Stop Frequency for input. In this mode, parameters you specified are always shown at the lower left and right side of the grid.

Key points:

 The span and center frequency are changed automatically according to the stop frequency. The

change of the span would have influence on other system parameters. For more details, please refer to “Span”.

 You can modify this parameter using the numeric keys, knob, or direction keys. Table 2-3 Stop Frequency

*Note：The range is from 100 Hz to 3.0GHz in non-zero span.
