The Anritsu 37347A Vector Network Analyzer covers 40MHz to 20GHz and has a built-in S-Parameter Test Set The Anritsu 37347A features LOG/LIN/Phase magnitude Smith charts, 6 independent markers, marker sweep, a 7.5" color VGA display, trace overlay, trace memory, autoscale, dual source control. 40 MHz to 20 GHz Fast Sweeping Synthesized Source Auto Reversing Test Set Solid-State Transfer Switch Four Independent Display Channels Four Channel Receiver Internal Hard and Floppy Disk Drives LRL/LRM Calibration Adapter Removal Calibrations Fast Measurement Throughput via GPIB Built-In AutoCal Control These network analyzers integrate a synthesized source, S-parameter test set and tuned receiver into a single compact package that is ideal for bench-top testing. One source of potential errors and inaccuracies in any network analyzer system is the calibration of that system. The Anritsu AutoCal automatic calibrator is designed to speed and simplify the calibration. Using the built-in software support and an AutoCal module connected to the serial port on the rear panel of the instrument, you are ready to make fast, accurate, and repeatable calibrations.
