How the VNA operates How the VNA operates The TTR500 series VNAs operate over frequency ranges of 100 kHz – 3 GHz (TTR503A) and 100 kHz – 6 GHz (TTR506A). The VNA measures RF and microwave electronic components by: Providing a stimulus signal that is stepped over a range of measurement frequencies.
RF source feed to the directional coupler. The signals become an output from the measurement port. This output signal is used as a stimulus for S-parameter measurements. Receivers There are 6 receivers in the TTR500 series VNA device. Each receiver can measure the magnitude and phase of a signal. Incident receivers (b Each measurement port has a receiver that measures the signal incident to the port.
Product information Device information The USB 2.0 provides bidirectional communication between the TTR500 series VNA and the host computer. Use a cable to connect the USB port on the VNA to either a USB 2.0 or a USB 3.0 port on a computer.
