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.

  • Master Sync and Master Clock Reference Timing Within a Facility
    Master Sync and Master Clock Reference Timing within a Facility Application Note Introduction becomes challenging and even more critical. The Tektronix SPG8000 and TG8000 are multi-format test signal and master Adjusting system timing and achieving synchronization is one sync generator platforms that can be configured with a variety of the most fundamental and critical procedures in a facility. of options to serve the analog, Standard Definition (SD)-Serial With multi-format facilities operating in the analog, digital and Digital Interface (SDI), High Definition (HD)-SDI and multi- standard or high definition environments, synchronization format master synchronization needs of a facility. Application Note Figure 2. Simple Differentiating circuit to extract sync. Figure 1. Synchronizing process. To understand how synchronization is achieved, we need to understand the basics of analog timing and how it works (Figure 1). For accurate reproduction of the image, both the camera and the television receiver must be synchronized to scan the same part of the picture at the same time. At the end of each horizontal line, the beam must return to the left side of the picture. This is called “horizontal retrace”. The horizontal sync pulse handles coordination of the horizontal retrace. Figure 3. Simple integrating circuit to extract vertical sync pulses. At the bottom of the picture, when the end of active picture is reached, it is time for the beam to return to the top of the picture. The vertical sync pulse, which is different in width was used in the sync separator to extract the horizontal than horizontal sync pulses, signals the start of the vertical drive signal for the receiver.
