Tektronix enters VNA market with USB product

April 26, 2017 // By Jean-Pierre Joosting
Tektronix has introduced the TTR500 Series USB Vector Network Analyzer, adding to the growing Tektronix portfolio of disruptive USB-based RF test instruments.

Like the company's highly successful USB-based spectrum analyzers, the latest TTR500 Series delivers an unmatched combination of low price and performance – 40 percent lower cost than alternatives capable of matching its 122 dB dynamic range and 6 GHz frequency range. It also includes advanced features including new VectorVu-PC analysis software and the only built-in bias tee for testing active devices in this category.  

Among the markets with a critical need for an affordable VNA are Internet of Things (IoT) design and education. VNAs help IoT designers match Bluetooth, WLAN, RFID and other radios to antennas. In many cases, designers must rent or borrow VNAs, adding time and expense to projects. In education, the high cost of VNAs means students get little to no hands-on time with an important instrument. The TTR500 Series dramatically lowers the barrier to entry and features an easy-to-use user interface for common tasks. Its small, compact form factor eliminates the need to roll around a shared VNA.

"With its innovative architecture and disaggregated design, the TTR500 Series achieves the same level of performance as a benchtop VNA, but at 40 percent lower cost and one-seventh the size and weight of units with comparable performance," said Jim McGillivary, general manager of RF and Component Solutions at Tektronix. "This new architecture also reduces component count and complexity for more reliability compared to benchtop VNAs."

The TTR500 Series offers a full 2-port, 2-path S-parameter VNA for such applications as measuring passive/active components, antennas and matching networks, RF modules, test cables, adapters and more. It features a solid set of specifications including 100 kHz to 6 GHz frequency range, 122 dB dynamic range, less than 0.008 dB trace noise, and -50 to +7 dBm output power, all in a compact package weighing less than 4 pounds.
