Added Beneﬁts of Preselected Millimeter Measurements

Reduced overload from many signals

All versions of 8563A spectrum

analyzers and 70907B external mixer

interface modules are fully compatible

with the 11974 Series.

System conﬁguration

Preselected millimeter mixers reduce

susceptibility to overloading by

numerous signals. Overloading can

cause your measurements to be

uncalibrated.

To operate your 11974 Series

preselected millimeter mixer, simply

connect the tune+span output, local

oscillator output,¹and the IF input of

the spectrum analyzer to the mixer.

Select the appropriate analyzer using

the switch on the rear panel of the

mixer. Make two easy adjustments,

and you’re ready to make millimeter

measurements.

Greater dynamic range

Preselection improves dynamic range

when signals are sufficiently spaced.

The preselector allows only one of

these signals to reach the mixer at a

time. So internally produced distortion

products, such as third order

System amplitude accuracy

Millimeter preselection improves

system amplitude accuracy by

reducing the level of local oscillator

(LO) emissions back to the device

under test. Option 001 further

improves system amplitude accuracy

by adding an isolator in front of the

input filter. With Option 001, the RF

input VSWR is <1.6:1 in A, Q, and U

bands and <2.3:1 in V Band.

intermodulation, are reduced.

The 11974 Series connect to a

standalone power supply with a

convenient 6-foot cable. Use the

same power supply with any 11974

Series preselected mixer.

Ease of use

Operators no longer need to learn

techniques of signal identification.

Anyone familiar with preselected

microwave spectrum analyzers can

quickly and easily make millimeter

measurements. Spurs from a device

under test are easily found. They

are not hidden by images or multiple

responses.

A full set of upgrade kits is available

to ensure compatibility with your

existing spectrum analyzers including

Agilent 8560A, 8561A/B, 8562A/B,

8566A/B, and E4440A/46A/48A PSA

Series. Refer to the compatibility table

to determine whether your spectrum

analyzer requires an upgrade.
