Contents
1. TDS2000C RIGOL DS1000E GW Instek GDS1000A U Both the GDS1000A U and DS1000E have more complicated board designs based on commercial components making the boards more than 2 times larger with 4 to 7 times more components implying lower reliability when compared to the TBS1000 and TDS2000C GDS1000A U and DS1000E both have fans which are components known to have very low reliability figures The need for a fan also indicates more power dissipation and thus more heat on the boards Heat can reduce the board s reliability GDS1000A U and DS1000E also use relays which are low reliability components and can further reduce the overall reliability of the instrument Tektronix Ask your customer Would you rather have an instrument the instrument will continue to support their with a Lifetime warranty and a design built for reliability or design projects for years to come and that it is an instrument with a limited warranty and a design that backed by the Tektronix lifetime warranty uses less reliable parts The TBS1000 and TDS2000C are 3rd generation products and continues to bring the highest quality lowest cost of ownership and best long term value to our customers The first generation TDS series launched 15 For education customers your students can years ago and quickly became popular with learn to operate one of the world s most popular customers because of its performance and oscilloscope platform2. is only warranted for 1 year The warranty is terminated at a period ending five 5 years after GW Instek discontinues manufacturing the warranted products This means that if a purchase is made within 1 2 years of the end of life the warranty is only 6 7 years The warranty can be as short as only 5 years if the product is purchased close to the end of the product s life cycle The TDS2000C warranty period is guaranteed to be at least ten 10 years from the date of purchase Both the GDS1000A U and DS1000E use a fan as part of the cooling design As a moving part a cooling fan is not reliable for long term usage This is a major customer benefit Owning a TBS1000 or TDS2000C with a more complete warranty can reduce the cost of ownership and provide benefits for a longer period of time www tek com products oscilloscopes tds2000 Tektronix Confidential Board design Tektronix has been making oscilloscopes for over 65 years and has developed market leading technology that enables us to manufacture highly reliable products that save cost and energy The pictures below showing the main boards of TBS1000 and TDS2000C DS1000E and GDS1000A U demonstrate the differences in design sophistication The TDS board has a high level of integration which uses custom ASICs designed specifically for this class of instruments This results in an instrument that has fewer parts lower power consumption and higher MTBF figures Tektronix

4. GW Instek GDS1000A U and RIGOL DS1000E VS TBS1000 and TDS2000C Competitive Brief The Value to Customers GW Instek launched the GDS1000A U series in July 2011 and Rigol launched the DS1000E series in 2008 These products are aimed at low end oscilloscope customers typically found in the education basic manufacturing and small business market segments where price is very important Based on pricing these products have been especially popular with education customers in the developing countries like China Brazil and India The TBS1000 and TDS2000C series oscilloscopes are the Tektronix instruments that most often compete with these products This brief provides information regarding limitations of the GDS1000A U and Rigol DS1000E series that many customers may not know Competitors advertised specs and features DS1000E GDS1000A U i alo e 150 100 70MHz Bandwidths 2 channels 1GSa s Real Time Sample Rates Maximum 25GSa s Equivalent Time 2Mega Points Record Length Up to 27 Automatic Measurements 5 7 TFT LCD Display USB Host and Device Interface Supported Go NoGo Function Data Logger Limited Lifetime Warranty www tek com products oscilloscopes tds2000 Tektronix Confidential di volt e 50 100MHz Bandwidths 2 analog channels e 1GSa s maximum real time sample rate and 25GSa s equivalent time sample rate e 5 6 TFT LCD QVGA 320X240 with 64K color LED backlighted display e Trigger modes edg
