Keysight phase noise analyzers come in two classes. The PN3-class includes E5045A-E5047A signal source analyzers, and PN7 includes E5055A-E5058A signal source analyzers.
E5057A SSA-X signal source analyzer (1 MHz to 44 GHz) provides precise and accurate measurements in one box for Phase Noise and Signal Source Analysis (SSA).
| Maximum frequency | 44 GHz |
| Maximum offset frequency | 8 GHz |
| Absolute phase noise sensitivity (10 GHz @ 10 kHz offset, Xcorr=1) | -149 |
| Residual phase noise sensitivity (10 GHz @ 10 kHz offset, Xcorr=1) | -160 dBc/Hz |
Detects low-level phase noise and spurious signals with high sensitivity, enabling precise characterization of signal sources and reliable performance of DUTs.
Uses dual independent channels to actively suppress internal noise through cross-correlation, enabling precise and reliable measurement of signal sources with minimal phase noise.
Purpose-built to accurately measure absolute and residual phase noise of both pulsed and non-pulsed signals, enabling comprehensive evaluation of overall system and component-level performance.
Measures amplitude modulation (AM) and baseband noise, both of which can degrade error vector magnitude (EVM) in digitally modulated signals and contribute to overall phase noise performance.
| Maximum frequency | 7 GHz to 54 GHz |
| Maximum offset frequency | 160 MHz to 8 GHz |
| Absolute phase noise sensitivity (10 GHz @ 10 kHz offset, Xcorr=1) | -149 dBc/Hz to -153 |
| Residual phase noise sensitivity (10 GHz @ 10 kHz offset, Xcorr=1) | -187 dBc/Hz to -150 dBc/Hz |
