Measurement Groups: FFT, Correlation, Time Histogram, Swept-Sine, Order Tracking
Frequency:
Range: 102.4 kHz or 100 kHz (both displays have the same range)
FFT spans: 195.3 mHz to 102.4 kHz or 191 mHz to 100 kHz. The two displays can have different spans and start frequencies.
FFT resolution: 100, 200, 400 or 800 lines
Real-time bandwidth: 102.4 kHz (highest FFT span with continuous data acquisition and averaging)
Accuracy: 25 ppm from 20 °C to 40 °C
Dynamic Range:
Dynamic range: 90 dB typical, 80 dB guaranteed (FFT and Octave). 145 dB typical (Swept-Sine). Includes spurs, harmonics, intermodulation distortion, and alias products. Excludes alias responses at extremes of span.
Harmonic distortion: <-80 dB (single tone in band)
Intermod. distortion: <-80 dB (two tones in band, each less than -6.02 dBfs)
Spurious: <-80 dBfs
Alias responses: <-80 dBfs (single tone outside of span, <0 dBfs, less than 1 MHz)
Full span FFT noise floor: -100 dBfs typical (input grounded, >-30 dBV, Hanning window, 64 rms averages)
Residual DC response: <-30 dBfs (FFT with Auto-Cal on)
Amplitude Accuracy:
Single channel: ±0.2 dB (excluding window effects)
Cross channel: ±0.05 dB, DC to 102.4 kHz (frequency response measurement, both inputs on the same range, rms averaged)
