8563E frequency analyser

The HP 8563E is a portable microwave spectrum analyzer introduced by Hewlett-Packard (now Keysight), offering standard frequency coverage from 9 kHz to 26.5 GHz (with preselector for the 2.75 GHz to 26.5 GHz band). It can be optionally equipped with Option 006 to extend the low-frequency range down to 30 Hz. Combining the high performance of a benchtop analyzer into a rugged, portable design compliant with MIL-T-28800 military standards, it withstands harsh environments and meets precise measurement requirements in applications such as RF communication testing, microwave device development, and electronic equipment manufacturing. Main Features Frequency and Resolution Performance: Standard frequency range of 9 kHz to 26.5 GHz, with optional range from 30 Hz to 26.5 GHz; offers fast digital resolution bandwidths of 1 Hz, 3 Hz, 10 Hz, 30 Hz, and 100 Hz, combined with a precision timebase and 1 Hz counter resolution. Signal Measurement Capability: Low Display Average Noise Level (DANL) down to -151 dBm/Hz, phase noise below -113 dBc/Hz at 10 kHz offset, and wide dynamic range; supports adjacent channel power, channel power, carrier power, occupied bandwidth percentage, and time-gated measurements. Specialized Test Functions: Built-in dedicated software for digital radio and phase noise measurements; time-gated analysis accurately captures pulsed RF signals and time-variant signals such as TDMA, supporting burst carrier testing across various digital modulation formats. Expansion and Compatibility: Can be extended into millimeter-wave bands using the 11970 series harmonic mixer or 11974 series preselector mixer; supports optional accessories including 007 Fast Time-Domain Scan and 008 Signal Recognition; standard large-capacity storage module compatible with multiple measurement cards. Accuracy and Durability: Features ±1.0 dB absolute amplitude accuracy and strong anti-interference capability; robust and portable design meets both laboratory precision testing and field deployment requirements.
