38. Displayed Average Noise Level: Agilent E4407B and E4408B
6. If the analyzer does not have Option 1DN (3.0 GHz Tracking
Generator) installed and the minimum RBW is 100 Hz or 10 Hz,
continue with step 12.
7. If the analyzer has a minimum RBW of 1 kHz or has Option 1DN
(3.0 GHz Tracking Generator) installed then continue with step 8.
8. On the analyzer, press the following keys:
AMPLITUDE, Attenuation, 0 dB
SPAN, 20 kHz
BW/Avg, Res BW, 1 kHz
BW/Avg, Video BW, 30 Hz
9. On the analyzer, press Single.
10.On the analyzer, press Peak Search (or Search) and record the
amplitude reading below as Meas Amptd(1 kHz RBW).
Meas Amptd(1 kHz RBW)____________ dB
11.Calculate the necessary reference level offset by subtracting the
Meas Amptd in step 10 from the Ref Amptd in step 5. If the
calculated Ref Lvl Offset is greater than 0.05 dB or less than –0.05
dB, record the Ref Lvl Offset value below. Otherwise, enter 0.
Ref Lvl Offset(1 kHz RBW)____________ dB
12.If the analyzer is not equipped with Option 1DR, continue with step
17.
13.On the analyzer, press the following keys:
AMPLITUDE, Attenuation, 0 dB
SPAN, 500 Hz
BW/Avg, Res BW, 10 Hz (E4407B)
BW/Avg, Res BW, 100 Hz (E4408B)
BW/Avg, Video BW, 1 Hz
14.On the analyzer, press Single.
15.On the analyzer, press Peak Search (or Search) and record the
amplitude reading below as Meas Amptd(100 Hz/10 Hz RBW).
Meas Amptd(100 Hz/10 Hz RBW)____________ dB
16.Calculate the necessary reference level offset by subtracting the
Meas Amptd in step 15 from the Ref Amptd in step 5. If the
calculated Ref Lvl Offset is greater than 0.05 dB or less than
–0.05 dB, record the Ref Lvl Offset value below. Otherwise, enter 0.
Ref Lvl Offset(100 Hz/10 Hz RBW)____________ dB
