Power Detection Analysis
Detects and analyzes time-domain signals within the analysis bandwidth for in-band power-versus-time relationships, including pulse signal measurements.
Real-Time Spectrum Analysis
A high-speed FPGA-based FFT engine provides strictly gapless and overlap-free FFT processing for real-time monitoring across the full analysis bandwidth.

Supports 2ASK, 2FSK, 4FSK, GMSK, BPSK, QPSK, 8PSK, 16QAM, 64QAM, 128QAM and 256QAM signals. Additional modulation and rate details are listed in the specification tables.
Harmonic Analysis
Detects and measures up to 10 harmonic components, including harmonic peaks, harmonic channel power and total harmonic distortion.
Phase Noise Measurement
Supports frequency offsets from 1 Hz to 10 MHz for carrier phase-stability evaluation. Automatic carrier search locates the target carrier without manual adjustment.
Pulse Analysis (Option 72)
Measures pulse widths from 64 ns at standard bandwidth, or from 32 ns with Option 50. Displays Top Level, Base Level, Top/Base, Droop, OverShoot, Ripple, Rise/Fall Time, Rise/Fall Edge, Width, PRI and Duty Cycle.

Additional product details

The YSA-P090 extends the handheld platform’s frequency range to 9 GHz.

The YSA-P090 supports GNSS frequency calibration, SCPI remote control and battery operation up to 2.5 hours, and a 9 GHz tracking generator is available as Option 62.

Key Capabilities & Applications

Extend measurements to 9 GHz

The frequency range covers 9 kHz to 9 GHz. Select Option 62 when a built-in 9 GHz tracking generator is required.

Separate measurement modes

Real-time analysis and IQ streaming accompany spectrum sweep. Phase-noise specifications distinguish spectrum sweep from dedicated phase-noise measurement mode.

Add the required analysis options

Option 50 provides 100 MHz analysis bandwidth. Options 71, 72 and 74 add basic vector modulation, pulse analysis and EMI pre-compliance measurement respectively.

Common applications

Interference hunting
EMC pre-compliance testing
Radar and wireless signal analysis
Laboratory RF measurements

Performance notes

The YSA-P090 SSB phase-noise figures depend on the measurement mode: SSB phase noise in spectrum sweep mode < -110 dBc/Hz at 1 GHz carrier, 10 kHz offset, and SSB phase noise in phase noise measurement mode < -124 dBc/Hz (typ.) at 1 GHz carrier, 10 kHz offset.

The YSA-P090 SSB phase-noise tables in phase noise measurement mode list two values per offset for each carrier: at 1 GHz (guaranteed / typical); at 4.5 GHz (guaranteed / typical); at 6 GHz (guaranteed / typical); at 9 GHz (guaranteed / typical).

The YSA-P090 sweep-speed figures are stated with Spur Rejection = Bypass.
