Other notes
- Spectrum analysis 4992A-S02 and oscilloscope 4992A-S01 are optional functions, not default features on every unit. English interface, external accessories, metrology and extended warranty services depend on the ordered configuration.
- 20 W is the upper limit of the listed internal T/R power-meter measurement range. 50 W, 150 W and 200 W are power ratings of external attenuator options, not direct instrument-port input ratings. Confirm attenuator, connection and compensation settings for high-power tests.
- Power-meter accuracy ±1 dB applies only within 20-43 dBm. Noise level -120 dBm is typical at the ANT port with 10 kHz bandwidth, not a guarantee under all test conditions.
- Vp and mVp denote peak voltage; Vrms and mVrms denote RMS voltage. Ranges, ports and applicable accuracy conditions are not interchangeable. Dimensions exclude the handle and similar parts, with the rear support closed.
- DC-9 GHz for 20201A and 20201B is the calibration-kit frequency range, not an extension of the 4992A source 1 or source 2 range. Compatible interfaces and connection accessories must be selected separately.
- Some battery and adapter entries appear both in the option list and the included accessories. Whether they are extra units or spares depends on the order list; do not count them twice. Individual accessory quantities are not specified in the catalog.
- The image shows a representative 4992A instrument configuration. Function options, accessories and screen displays depend on the ordered configuration. Provide device type, frequency band, test items, interfaces, power, configuration and quantity; lead time and services are subject to quotation.
