b) Tap the "Frequency" button.
c) In the "Center" field, enter 64 on the number pad on the front panel.
d) Press the "MHz" key next to the number pad.
2. Reduce the span to 20 MHz:
a) In the "Span" field of the "Frequency" dialog box, enter 20
MHz.
b) Close the "Frequency" dialog box.
3. Set the reference level to -25 dBm:
a) In the configuration "Overview", tap the "Amplitude" button.
b) In the "Value" field of the "Amplitude" dialog box, enter -25
dBm.
