February 28, 2013. Rohde & Schwarz announced it has added the rugged, passive R&S RT ZZ80 broadband probe to its portfolio. This probe, recommended for the R&S RTO oscilloscope, offers a bandwidth of 8 GHz. The company said that for analyzing electronic circuits, passive broadband probes such as the R&S RT-ZZ80 are a cost-efficient, rugged alternative to active, high bandwidth probes and are suited for testing transmission lines with low impedance (20 Ω to 100 Ω).
Users in the most diverse of industries, from consumer electronics to medical engineering and aerospace and defense, can use the R&S RT-ZZ80 to perform precision analyses on electronic circuits. The Rohde & Schwarz portfolio of probes now offers a probe for multiple broadband applications. The family of differential broadband probes includes the active differential R&S RT ZD40 model (4.5-GHz bandwidth). Single-ended probes, including the R&S RT-ZS60 (6-GHz bandwidth), make it possible to test ground referenced signals, even at high amplitudes of up to 8 V.
The company also introduced the R&S RT-ZF20 deskew fixture, which ensures voltage and current signals are accurately aligned when performing power measurements. The deskew fixture makes it easy to measure delay differences, which can then be corrected in the oscilloscope. The fixture was used in conjunction with the R&S RTM universal oscilloscope in a power-measurement demonstration at the embedded world 2013 trade fair this week.
