35. Displayed Average Noise Level: Agilent E4401B and E4411B

Generator) installed and the minimum RBW is 100 Hz or 10 Hz,

continue with step 10.

6. If the analyzer has a minimum RBW of 1 kHz or has Option 1DN or

1DQ (1.5 GHz Tracking Generator) installed then continue with step

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, Peak Search (or Search) and record the

amplitude reading below as Meas Amptd(1 kHz RBW).

Meas Amptd (1 kHz RBW) ____________ dBm (50 Ω Input only)

Meas Amptd (1 kHz RBW) ____________ dBmv (75 Ω Input only)

9. Calculate the necessary reference level offset by subtracting the

Meas Amptd in step 8 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

10.If the analyzer is not equipped with Option 1DR, continue with step

14.

11.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 (E4411A)

BW/Avg, Video BW, 1 Hz

12.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) ____________ dBm (50 Ω Input

only)

Meas Amptd (100 Hz/10 Hz RBW) ____________ dBmv (75 Ω Input

only)

13.Calculate the necessary reference level offset by subtracting the

Meas Amptd in step 12 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.
