- Resolution bandwidth: 1 Hz to 10 MHz in 1/2/3/5 step increments
- 5-pole resolution filters with high selectivity
- FFT filter with 1 Hz to 1 kHz RBW for fast measurements
- Displayed average noise floor: −150 dBm typical (10 Hz bandwidth)
- Dynamic range: 75 dB ACPR (WCDMA, 4.096 MHz integration)
- Alternate channel ACPR: 82 dB (WCDMA)
- True RMS detector for precision power measurements
- Spectrum sweep time: 5 ms (full span)
- Time domain analysis: 1 µs zero span sweep time
- Modulation analysis: I/Q signals, vector and constellation diagrams
- Input connector: 50 Ohm BNC(f)
