Operation

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.).

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 on page 55. 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 “Harmonic 6L”, where “L”
