Performance Verification Tests

7. Noise Sidebands

Procedure

This performance test consists of five parts:

Part 1: Noise Sideband Suppression at 10 kHz (measured in 1 kHz

RBW)

Part 2: Noise Sideband Suppression at 10 kHz (measured in 100 Hz

RBW)

Part 3: Noise Sideband Suppression at 20 kHz

Part 4: Noise Sideband Suppression at 30 kHz

Part 5: Noise Sideband Suppression at 100 kHz (Agilent E4401B and

E4411B only)

• For E4401B or E4411B, do Parts 1, 3, 4 and 5.

• For E4402B, E4404B, E4405B or E4407B with Option 1DR and

serial prefixes greater than or equal to US4510, SG4510, or MY4510,

do Parts 2, 3 and 4.

• For all other ESA series analyzers do Parts 1, 3 and 4.

A worksheet is provided at the end of this procedure for calculating the

noise sideband suppression.

Part 1: Noise Sideband Suppression at 10 kHz (measured in

1 kHz RBW)

1. Perform the following steps to set up the equipment:

Set the synthesized signal generator controls as follows:

FREQUENCY, 1000 MHz

AMPLITUDE, 0dBm (50 Ω Input only)

AMPLITUDE, 6 dBm (75 Ω Input only)

AM OFF

FM OFF

2. Connect the equipment as shown in Figure 2-7.

3. Press Preset on the analyzer. Press the Factory Preset softkey, if it is

displayed. Set the analyzer by pressing the following keys:

FREQUENCY, 1 GHz

SPAN, 10 MHz

AMPLITUDE, Attenuation 10 dB (Man)

4. Press the following analyzer keys to measure the carrier amplitude:

Peak Search (or Search)

FREQUENCY, Signal Track (On)

SPAN, 50 kHz

BW/Avg, 1kHz

Video BW, 30 Hz (Man)

FREQUENCY, Signal Track (Off)
