Performance Verification Tests
36. Displayed Average Noise Level: Agilent E4402B and E4403B
continue with step 11.
6. If the analyzer has a minimum RBW of 1 kHz or has Option 1DN
(3.0 GHz Tracking Generator) installed then continue with step 7.
7. 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
8. On the analyzer, press Single.
9. 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)____________ dBm
10.Calculate the necessary reference level offset by subtracting the
Meas Amptd in step 9 from the Ref Amptd in step 4. 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
11.If the analyzer is not equipped with Option 1DR, continue with step
15.
12.On the analyzer, press the following keys:
AMPLITUDE, Attenuation, 0 dB
SPAN, 500 Hz
BW/Avg, Res BW, 10 Hz
(E4401B)
BW/Avg, Res BW, 100 Hz (E4403B)
BW/Avg, Video BW, 1 Hz
13.On the analyzer, press Single, 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
14.Calculate the necessary reference level offset by subtracting the
Meas Amptd in step 13 from the Ref Amptd in step 4. 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
15.On the analyzer, press
Input, Amptd Ref Out (Off), then AMPLITUDE,
More, Ref Lvl Offst
, and enter the value recorded in step 10.
16.Connect the 50
Ω termination to the analyzer input as shown in
