  • 1. TEST REPORT DVB Combo Signal Analyzer 8dtek TSM-8800 Digital Signal Analyzer for DVB-S and DVB-T Signals Solid Design and Fully Featured! Since the beginning of the satellite age there was always this one problem for the die-hard satellite hobbyist: the necessary hardware to properly align his own antenna, that is, a satellite signal analyzer was always ridiculously expensive. When the transition to digital transmissions began, it finally became possible to offer signal analyzers with professional features at much lower prices. 0.6 26 TELE-satellite — Global Digital TV Magazine — 04-05/2010 — www.TELE-satellite.com

For one thing, this helps analyzer using a mini remote without a doubt fulfills both of our demands, is the TSM-8800 from 8dtek. 8dtek from Hong- kong was founded in 2008 and specializes in sophisticated, highly technical solutions. The TSM-8800 is a perfect example of that. When we opened up the box, it was obvious that 8dtek did not skimp on quality nor on any of the included acces- sories. Absolutely solid and sturdy; there’s no other way to describe it. The electronics were placed in a solid, brushed aluminum chassis. The analyzer itself sits nicely in your hand and is protected from falls and other environ- mental concerns. The manu- facturer also surrounded the analyzer in a rubber jacket with openings for connectors on the underside as well as the upper and lower edges. This rubber jacket prevents the analyzer from slipping on almost any surface. Because of its rela- tively heavy weight, it sits sol- idly in place and thus makes it all the more easier to use. The front panel sports a 3.5- inch LCD display. It’s very easy to read and produces very little glare even with direct sun- light. Six LEDs are located just below the display and indicate the current operational mode of the analyzer. At one glance you can identify the current polarization level as well as the current band (high or low) and whether or not the analyzer has locked on to a signal. 8dtek incorporated an infra- red receiver right in the middle of the row of LEDs. Wait a minute… an infrared receiver for a signal analyzer? Actually, it’s not a bad idea! The signal www.TELE-satellite.com — 04-05/2010 — TELE-satellite — Global Digital TV Magazine 27
