The Anritsu 37397A is a microprocessor controlled Vector Network Analyzer. It integrates a synthesized source, S-parameter test set and tuned receiver into a single compact package that is ideal for bench-top testing. It provides: 40 MHz to 65 GHz, Fast Sweeping Synthesized Source, Auto Reversing Test Set, Solid-State Transfer Switch, Four Independent Displays, Internal Hard and Floppy Disk Drives, LRL/LRM Calibration, Adapter Removal Calibrations and Fast Measurement Throughput via GPIB. Specifications. Frequency Range: 40 MHz to 65 GHz. Dynamic Range (“Receiver Dynamic Range” is defined as the ratio of the maximum signal level at Port 2 for 0.1 dB compression to the noise floor at Port 2.; “System Dynamic Range” is defined as the ratio of the power incident on Port 2 in a through line connection to the noise floor at Port 2 (forward measurements only). 10 Hz IF bandwidth and 512 averages were used in calibration and measurement.) Max Signal Into Port 2: 30 dBm. Noise Floor: -77 dBm @ 0.04 GHz, -105 dBm @ 2 GHz, -97 dBm @ 20 GHz, -95 dBm @ 40 GHz, -87 dBm @ 50 GHz, -77 dBm @ 65 GHz. Receiver Dynamic Range: 107 @ 0.04 GHz, 135 @ 2 GHz, 127 @ 20 GHz, 125 @ 40 GHz, 117 @ 50 GHz, 107 @ 65 GHz. Port 1 Power: 10 dBm @ 0.04 GHz, -2 dBm @ 65 GHz. System Dynamic Range: 70 @ 0.04 GHz, 70 @ 65 GHz, Max. 98 @ 2 GHz. High Level Noise (typical): <.04 dB and <.5° peak-to-peak variation in a 1 kHz IF bandwidth up to 20 GHz, <.08 dB and <.0° peak-to-peak variation up to 40 GHz, <.25 dB and <.5° peak-to-peak variation up to 65 GHz. Measurement Time vs. Span for 101 Data Points (typical): 40 MHz to 20 GHz, 500 ms. Number of Channels: Four independent measurement channels.
