Expand Carrier Frequencies to

110 GHz

For absolute measurement of phase

noise in the millimeter frequency

bands, add the appropriate Agilent

11970 series millimeter harmonic

mixers to E5504A solutions.

The 26.5-GHz microwave downcon-

verter provides the high power, direct

LO drive necessary to downconvert

millimeter signals. The 45-dB variable

gain IF amplifier is available to amplify

the IF output of the harmonic mixer.

The downconverter can also supply

the DC bias to the harmonic mixer if

appropriate.

Quick and Easy Integration Into

Your ATE System

With a completely defined, industry

standard SCPI programming interface

client, the E5500 A-series can be

quickly and easily integrated into your

specific ATE computing environment.

If you choose to configure an E5500

series solution to run on a separate

computer, initiate a measurement

over LAN or GPIB using the standard,

remote, phase noise SCPI command

language.

Full measurement system control,

including capturing measurement

data, is included. If your production

ATE computing environment runs

under Windows NT® 4.0, a separate

computer is not necessary. Simply

initiate a measurement using the

multitasking capability and the

remote SCPI interface to communi-

cate with the E5500 series measure-

ment software running concurrently

on your ATE computer.

Data is available in two ASCII for-

mats: a spread sheet format and an

XY graph format. Other data transla-

tors can be specified and provided.

Software summary:

• Modular, object oriented,

client/server architecture

• Windows 95®–compliant graphical

user interface

• Industry standard SCPI program-

ming language
