Configuration and ordering
- The model, port count and frequency options determine the operating range. High-frequency entries shared by C/D/E apply only to models covering that band. The 3671G standard/-400 covers 43.5 GHz; -210/-410 covers 40 GHz.
- System dynamic range is measured at 10 Hz IF bandwidth using RMS. Amplitude/phase trace noise is measured at -5 dBm excitation, 1 kHz IF bandwidth and through transmission.
- Minimum output power and power sweep range are typical values; account for power accuracy. Select maximum-output and dynamic-range values matching the port and frequency configuration.
- Options, calibration kits, test cables, calibration and extended-warranty services are selected in the quotation/order, not all included as standard. Confirm regions, duration and shipping responsibilities when requesting a quote. Warranty extensions exclude metrological calibration.
- Advanced time-domain virtual eye diagrams are simulated from S-parameters, not direct standalone-oscilloscope acquisition or bit-error-rate measurements.
- The image shows a 3671L four-port configuration as a series representative. Not every model or quotation includes four ports; the model and delivery configuration are confirmed in the order.
