For reliable results, the instruments have to be up to the task and all settings must be correct. High-end T&M instruments make things easier in this respect. Their performance qualifies them for virtually any challenge that modern technology can pose. Wizards, automatic functions and software for many special tasks help users prevent mistakes and get answers quickly. A capable and efficient high-end instrument also has a certain flair that makes it a pleasure to work with – no small matter considering how much they are used in everyday lab work. Many of the instruments featured in this issue fall in this category. With the R&S®RTP oscilloscopes, Rohde & Schwarz has entered the high-performance segment of this instrument class (page 42). Initially available up to 8 GHz, they are ideal for measure- ments on fast buses and complex embedded designs. The R&S®RTP is the first oscilloscope that can compensate for impairments caused by components in the signal path through realtime hardware deem- bedding, ensuring consistently reliable measurement results. The R&S®FSW signal and spectrum analyzer has been on the market for a while and has built up a reputation as a reference instrument. Now it has been further enhanced (page 58). With its 2 GHz internal analysis bandwidth, 800 MHz real-time bandwidth and low phase noise, it is the benchmark when it comes to evaluating wideband commu- nications systems and high-resolution radars. The brand new, mid- range R&S®FSV3000/FSVA3000 analyzers are also a good choice for demanding measurements. They offer surprisingly innovative automatic features such as an event driven GUI and a synchronizing function for connected generators – and the performance data to match (page 64).
