Selection and operating notes
- Choose 3926B, E, H or L for the required upper frequency. 8 kHz–67 GHz is the series coverage, not the range of every configuration; band-specific performance applies only within the selected model's coverage.
- 160 MHz analysis bandwidth is standard. 1 GHz/2 GHz bandwidth, protocol identification, digital-phosphor spectrum and recording functions depend on option combinations and are not all included by default.
- The 5 THz/s scan specification requires 1.25 MHz resolution, the 1 GHz analysis-bandwidth option and start frequency ≥750 MHz. Select options for the actual signal and scanning task.
- Low-noise and low-distortion modes have different performance conditions. Typical noise figure does not replace specified limits; observe the maximum input power for each band.
- Match fiber-interface bandwidth to receiver analysis bandwidth and recording configuration. Inclusion of external recorders, interfaces and storage upgrades is defined by the quotation and order.
- Photo represents the series appearance. Supplied model, configuration, accessories, lead time and services are confirmed in the formal quotation and order.
