Measurement Summary
1. Connect the spectrum analyzer CAL OUT to the INPUT
5OQ
and press the (PRESET_) key.
2. Set the center frequency by pressing the following keys:
[FREQUENCY),
300
CMHz).
3. Set the span by pressing the following keys:
ISPAN),
20
m.
4. The calibration signal is 20
dB
(two graticule divisions) below the top of the screen using
these spectrum analyzer settings. If desired, adjust the reference level: press [AMPLITUDE) to
activate the reference level, and use the knob or step keys to change the reference level.
5. Determine the amplitude and frequency of the signal. You can either press
[PEAK
SEARCH]
or
press
m
and move the marker to the signal peak. Read the amplitude and frequency.
The display screen should look like the one in Figure 2-6. Frequency is displayed
horizontally, and amplitude (power) is displayed vertically.
