SilverLine

-VNA

(18, 26.5 and 40 GHz)

Vector Network Analyzer Test Cables：

• Vector Network Analyzer Measurements

• Laboratory Use

• Research and Development

SilverLine®-VNA is a precision test cable with excellent

loss, VSWR and phase/ﬂexure stability. Protected by a

torque and crush resistant armor, SilverLine®-VNA test

cables exhibit extraordinary ruggedness comparable to

OEM supplied test cables but at a fraction of the cost ,

making them the ideal choice for daily use in factory and

lab applications .

The braided PET outer jacket makes SilverLine®-VNA easy

to handle, non-conductive and improves ﬂexibility when

compared to extruded jackets . The chrome plated metal

back shell maintains the integrity of the cable to connector

interface and allows for easy handling.

• 18, 26.5 and 40 GHz options

• Low loss 40 GHz cables now available!

• Phase, Loss & VSWR stable

• High ﬂex life

• Torque and crush resistant stainless steel armor

• Chrome plated strain relief back shells

A brand new cable can have a break-in period of several hundred ﬂexes.

Ordering Information:

*Requires mating connections to be clean and within mechanical speciﬁcations. Calibrated

torque wrench required.

**RF stability and ﬂex life are in accordance with the ﬂex test method example. Data is for cables

4ft or shorter. Longer cables may exhibit diﬀerent stability characteristics. A cable will exhibit some

instability when new. A very brief period of use is required to alleviate cable component stresses

from manufacturing after which the cable will “settle” and maintain the values stated

Flex Test (one full cycle)

While armored, 26.5 & 40 GHz cables are sensitive microwave instruments.

Small, ﬂexible cables can easily be forced beyond the recommended

minimum bend radius. This will likely degrade or destroy the RF

performance. All ﬂexible cables have a limited ﬂex life. Develop procedures

that limit ﬂexing. 2.4 and 1.85mm interfaces are delicate. Keep them

meticulously clean and the center contacts concentric within the outer

contact. Use a microscope to examine if necessary. DO NOT mate connec-

tors that are dirty, suspected of being damaged or outside concentric

tolerances. Connectors must be aligned when mating. Misalignment could

damage the interfaces and voids the warranty. Test equipment makers

publish extensive use and handling procedures on their web sites that

cover these and related topics.

Care and Handling Guidelines:

-Force the cable to bend beyond the recommended minimum radius.

-Force two connectors. If any resistance is felt STOP and examine.

-Mate to another series.

-Mate connectors that are not aligned and concentric.

-Put foreign or dirty objects into the interface.

NEVER:

ALWAYS:

-Inspect interfaces before every mate. Clean if needed.

-Gently start the coupling nut and fully thread with ﬁngers ﬁrst.

-Hand tighten, but if a calibrated torque wrench is used 8 lbs max.

-Limit use to experienced technicians.

-Cap connectors and store cables separately in a protective container.

-Keep a spare pair of cables ready, just in case.

Warranty:

Product to be free from workmanship and materials defects and to meet

stated data sheet performance for a period of 90 days. Excludes cable or

connector interface damage from misuse, abuse, mishandling or

mis-mating outside the data sheet recommendations. Warranty claims are

subject to factory analysis and may include analysis charges depending on

ﬁndings.
