Ultra-durable 75ohm test cables operate to 3GHz

17-03-2015 | Pasternack | Test & Measurement

Pasternack has released its newest line of 75ohm test cables with operation
up to 3GHz. The rugged cable assemblies are specially designed to withstand
the rigors of test lab use and applications in 75ohm communications systems.
Technicians commonly rely on these high-frequency test cables in
technologies such as cable TV, MoCA 2.0 and MoCA 1.1 (Media over Coax
Alliance) and DOCSIS (Data over Cable Service Interface Specifications).

The new test cables are available in two configurations including a type-N
male to type-N male or a type-N male to type-F male. Unlike most F
connectors readily available on the market, these F connectors are designed
to perform up to 3GHz which greatly broadens the usability and value of
these test cables. Moreover, the connectors are threaded to ensure an
accurate and secure connection to both the device under test as well as the
analyzer. The test cables are suitable for engineering labs, production
environments and quality testing facilities and are a good choice for use
with 75ohm S-parameter test systems.

The test cables exhibit exceptional insertion loss of < 0.5dB at 3GHz, and
typical return loss is 28dB. They are designed with an armoured jacket that
meets ANSI/SCTE 99 2009 pull force and ANSI/SCTE 98 2009 tightening torque
standards and are also capable of 100,000 bends minimum, says the company.

“Our new 75ohm test cables provide customers dealing with cable TV media
hardware, set top box manufacturers and broadcast engineers a new
cost-effective source for high frequency 75 Ohm testing components,” said
Steve Ellis, interconnect product manager, Pasternack.
