4. Select a start frequency and a stop frequency, or select a center frequency and a frequency
span:
• Start and stop frequency: Press the soft key under Start / Cntr to specify a start
frequency (ensure Start is highlighted, Figure 5-16). Use the navigation wheel with the
cursor keys to change the value, and then press another soft key to finish the entry and
exit. Or use the numeric keypad to enter a desired value and then press the soft key
under the desired units to finish the entry, or the soft key under Cancel to cancel the
changes. Press the soft key under Stop / Span to specify a stop frequency. Follow the
same value entry procedures.
• Center frequency and frequency span: Press the soft key under Start / Cntr to specify a
center frequency (ensure Cntr is highlighted). Use the navigation wheel with the cursor
keys to change the value, and then press another soft key to finish the entry and exit. Or
use the numeric keypad to enter a desired value and then press the soft key under the
desired units to finish the entry, or the soft key under Cancel to cancel the changes.
Press the soft key under Stop / Span to specify a span frequency. Follow the same
value entry procedures.
5. Press the soft key under Sweep / Time. Use the navigation wheel with the cursor keys to
