set from 10 Hz to 7.1 G. The Span can also be set to zero span for all models.

Figure 4-19. Span Menu Soft Keys
Span
This soft key shows the current value for span in units of GHz, MHz, kHz, or Hz. When
the Span button is pressed, span becomes the active parameter and may be changed.
Use the keypad, the directional arrow keys or the rotary knob to increase or decrease
the span frequency. If the span is changed by using the up and down arrow keys, the
span changes by the value of the Frequency Step entered in the Frequency menu.
Span Up 1-2-5
This is a convenient way to quickly arrive at a wider span value. The first time the soft
key is pressed, the span value increases to the nearest even value that starts with 1, 2,
or 5. For example if the span is 1.8 MHz, pressing the soft key for the first time changes
the span to 2.0 MHz, the next press takes the value to 5.0 MHz and so on.
Span Down 1-2-5
This is a convenient way to narrow the frequency span. The first time the soft key is
pressed, the span value decreases to the nearest even value that starts with 1, 2, or 5.
For example if the span is 1.8 MHz, pressing the soft key for the first time changes the
span to 1.0 MHz, the next press takes the value to 500 kHz, then 200 kHz and so on.
