Using the Mixers with the 8566B Spectrum Analyzer

Set up the equipment

1. Connect the external harmonic mixer to the spectrum analyzer, as shown in Figure 2-17.

NOTE

Good-quality shielded SMA-type cables should be used to connect the mixer to

 

the spectrum analyzer to ensure that no signal attenuation occurs. Agilent

 

5061-5458 SMA-type cables may be used. Do not over-tighten the cables; the

 

maximum torque should not exceed 112 N-cm (10 in-lb.).

Operation

CAUTION Before connecting the Agilent 11975A Amplifier, set the ALC switch to ON. Failure to do so can damage the mixer.

2.Power up the spectrum analyzer and then the amplifier.

3.Adjust the amplifier power to 16 dBm.

4.To access the spectrum analyzer’s millimeter bands, press SHIFT and then the up arrow ⇑ until the desired band is displayed on the screen, as shown in Figure 2-18. Note that this is important because toggling through the bands, causes the band to automatically harmonic lock as evidenced by the on-screen annotation of “Harmonic 6” changing to
