Additional Features: Fast Sweeping Synthesized Source Auto Reversing Test Set (37200C/37300C models only) Solid-State Transfer Switch (37200C/37300C models only) Four Independent Display Channels Multiple Source Control of Two External Sources Four Channel Receiver Internal Hard and Floppy Disk Drives LRL/LRM Calibration Adapter Removal Calibrations Fast Measurement Throughput via GPIB Built-In AutoCal® Control The Lightning 37247C Vector Network Analyzer (VNA) is a high performance tool designed to make fast and accurate Sparameter measurements of active and passive devices across the 40 MHz to 20 GHz range. 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. High throughput measurements are achieved in each model through the use of fast, 12-term error corrected sweeps, fast GPIB data transfers and an intuitive user interface. All measurement results are displayed on a large LCD color display or on an external VGA monitor.
