ROHDE & SCHWARZ EFA78 Datasheet

Test Equipment Solutions Datasheet Test Equipment Solutions Ltd specialise in the second user sale, rental and distribution of quality test & measurement (T&M) equipment. We stock all major equipment types such as spectrum analyzers, signal generators, oscilloscopes, power meters, logic analysers etc from all the major suppliers such as Agilent, Tektronix, Anritsu and Rohde & Schwarz. We are focused at the professional end of the marketplace, primarily working with customers for whom high performance, quality and service are key, whilst realising the cost savings that second user equipment offers. As such, we fully test & refurbish equipment in our in-house, traceable Lab. Items are supplied with manuals, accessories and typically a full no-quibble 2 year warranty. Our staff have extensive backgrounds in T&M, totalling over 150 years of combined experience, which enables us to deliver industry-leading service and support. We endeavour to be customer focused in every way right down to the detail, such as offering free delivery on sales, covering the cost of warranty returns BOTH ways (plus supplying a loan unit, if available) and supplying a free business tool with every order. As well as the headline benefit of cost saving, second user offers shorter lead times, higher reliability and multivendor solutions. Rental, of course, is ideal for shorter term needs and offers fast delivery, flexibility, try-before-you-buy, zero capital expenditure, lower risk and off balance sheet accounting. Both second user and rental improve the key business measure of Return On Capital Employed. We are based near Heathrow Airport in the UK from where we supply test equipment worldwide. Our facility incorporates Sales, Support, Admin, Logistics and our own in-house Lab. All products supplied by Test Equipment Solutions include: - No-quibble parts & labour warranty (we provide transport for UK mainland addresses). - Free loan equipment during warranty repair, if available. - Full electrical, mechanical and safety refurbishment in our in-house Lab. - Certificate of Conformance (calibration available on request). - Manuals and accessories required for normal operation. - Free insured delivery to your UK mainland address (sales). - Support from our team of seasoned Test & Measurement engineers. - ISO9001 quality assurance.

The instruments provide high-precision reception and demodulation of vestigial sideband AM signals (analog TV signals) as well as of digitally modulated TV signals. They measure a comprehensive range of transmission parameters and are therefore ideal for measurement and monitoring applications in cable networks, TV transmitter stations and development labs.
