d.
Modify the default settings:
H
Press the
FREQUENCY/CHANNEL
key on the front panel.
H
With the
Center Freq
side key, set the frequency to 100 MHz using
the numeric keypad.
H
Press the
SPAN
key on the front panel.
H
With the
Span
side key, set the span to 10 MHz using the general
purpose knob.
H
Press the
AMPLITUDE
key on the front panel.
H
With the
Ref Level
side key, set the reference level to --20 dBm
using the general purpose knob.
H
Press the
RF Atten/Mixer
side key to select
RF Att
.
H
With the
RF Att
side key, set the attenuation to 0 dB using the
numeric keypad or the general purpose knob.
2.
Measure the reference amplitude at 0 dB attenuation:
a.
Press the
PEAK
key on the front panel to place the marker on the peak.
b.
Record the peak amplitude at the marker readout as the reference value.
(Let the value be P
0.
)
3.
Check the amplitude for the attenuation from 5 to 30 dB:
a.
Press the
RF Att
side key and set the attenuation (initially 5 dB).
b.
Press the
PEAK
key on the front panel to place the marker on the peak.
c.
Record the peak amplitude at the marker readout. (Let the value be P
X
.)
d.
Check that the error (P
X
-- P
0
) is within
0.2 dB.
e.
Repeat substeps a through d for attenuation from 5 to 30 dB in 5 dB
steps.
4.
Modify the generator controls:
Amplitude
--5 dBm
