The Keysight N5181B-506 MXG X-Series analog signal generator operates from 9 kHz to 6 GHz, providing extended frequency coverage compared to the 503 model. This frequency range is ideal for applications requiring operation up to C-band frequencies, including satellite communications testing, radar development, and advanced wireless communications standards. The instrument maintains excellent frequency accuracy and stability across the entire range.
At 6 GHz carrier frequency, the N5181B-506 provides SSB phase noise specifications from 20 to 30 degrees C excluding mechanical vibration. Typical measured standard phase noise shows approximately -69 dBc/Hz at 10 Hz offset, -81 dBc/Hz at 100 Hz, -76 dBc/Hz at 1 kHz, -91 dBc/Hz at 10 kHz, -107 dBc/Hz at 100 kHz, -121 dBc/Hz at 1 MHz, and -126 dBc/Hz at 10 MHz offset. Enhanced phase noise options UNX and UNY provide significantly better performance.
The N5181B-506 extends the frequency range from 3 GHz to 6 GHz compared to the 503 model, while maintaining the same excellent performance characteristics. Both models share the same analog modulation capabilities, pulse modulation features, phase noise architecture, and connectivity options. The 506 model provides phase noise and harmonic specifications up to 6 GHz, making it suitable for higher frequency applications while preserving the precision and flexibility of the MXG platform.
The N5181B-506 provides absolute level accuracy specifications quoted between 20 and 30 degrees C. For temperatures outside this range, absolute level accuracy degrades by 0.01 dB per degree C, and output power may drift up to 0.10 dB below 3 GHz and 0.15 dB above 3 GHz per gram per kilogram change in absolute humidity. The instrument features excellent repeatability and relative level accuracy for precise amplitude control across the frequency range.
Yes, the N5181B-506 fully supports list mode sweeping with excellent switching speeds. With internal channel corrections enabled, the frequency switching speed is less than 1.3 ms measured for list mode and SCPI mode cached frequency points. The instrument automatically caches the most recently used 1024 frequencies, and there is no speed degradation for amplitude-only changes, making it ideal for automated test applications.
With Option UNW, the N5181B-506 includes a comprehensive internal pulse generator supporting free-run, square, triggered, adjustable doublet, trigger doublet, gated, and external pulse modes. The pulse generator offers square wave rates from 0.1 Hz to 10 MHz with 0.1 Hz resolution, pulse periods from 30 ns to 42 seconds, and pulse widths from 20 ns to pulse period minus 10 ns with 10 ns resolution. Option 320 adds pulse train generation with up to 2047 pulse patterns.
The N5181B-506 is well-suited for receiver sensitivity testing thanks to its excellent spectral purity, precise level accuracy, and low phase noise. Its ability to output calibrated signals across the full 9 kHz to 6 GHz range with tight amplitude control allows engineers to characterize receiver performance accurately. Option 1EQ extends the specified low power range down to -110 dBm for testing receivers at very low signal levels.
Key performance enhancement options include UNX (low phase noise) and UNY (enhanced low phase noise) for improved spectral purity, UNZ (fast switching) for faster frequency changes, 1EA (high output power) for increased power levels, UNW (narrow pulse modulation) for pulse applications, and 1EQ (low specified power) for extending the power range down to -110 dBm. Option 099 enables license key upgradability for future expansion without hardware changes.
