E8257DS02-S15

Introduction

The E8257DS02, S03, S05, S06, S08, S10, S12, and S15 are Millimeter-wave Source Modules

that are manufactured by Oleson Microwave Labs (OML) and is provided as an ordering

convenience by Keysight Technologies. This product can be ordered directly from OML. For

additional Millimeter-wave Source Modules information go to the Keysight website at

http://www.keysight.com/find

This product is warranted by OML against defective materials and workmanship. Refer to

documentation supplied with this product or go to http://www.omlinc.com for more

information.

A periodic calibration is not required for millimeter-wave modules.

Content list

Each source module ordered includes one each of the standard accessories listed below:

• Source Module Interface cable (2 meter)

• RF cable SMA (m) to SMA (m) (1 meter)

Description

The millimeter-wave source modules are designed to work with the E8247C, E8257C, E8257D,

E8267C or E8267D PSG Series Synthesized Sources.

The following list of adapters are required to connect the PSG RF Output to the millimeter-

wave source module RF Input. The adapter is included with the PSG product, but is not

included with the millimeter-wave source module. Refer to the following table for required

adapters.

The E8257DSxx millimeter-wave source modules can be driven directly from

the E8257D or E8267D-1EU Performance Signal Generators (PSGs) or from

other MXG/ESG Signal Generators with the OML VDCPW09-4, 9 VDC Power

Supply (7-pin output circular jack).

Only Keysight-approved accessories shall be used.
