The SR780 Dynamic Signal Analyzer combines high performance and low cost in a full-featured package. It offers 102.4 kHz dual-channel FFTs with 90 dB dynamic range, swept-sine measurements, ANSI standard octave analysis, waterfall displays and transient capture for less than half the cost of other similarly equipped analyzers.

Thông tin sản phẩm
Specifications apply after 30 minutes warm-up and within 2 hours of last auto-offset. Measured with 400 line resolution and anti-alias filters enabled unless stated otherwise.
Measurement Groups
Groups FFT, Octave Analysis, Swept-Sine
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

90 dB typical, 80 dB guaranteed.
145 dB 
Includes spurs, harmonic and 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 typ. (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 windowing)
Cross channel ±0.05 dB (DC to 102.4 kHz)
(transfer function measurement, both inputs on the same range, rms averaged)
Phase Accuracy
Single channel ±3.0 deg. relative to external TTL trigger (-50 dBfs to 0 dBfs, frequency <10.24 kHz, center of frequency bin, DC coupled).
For Blackman-Harris, Hanning, Flat-Top and Kaiser windows, phase is relative to a cosine wave at the center of the time record. For Uniform, Force and Exponential windows, phase is relative to a cosine wave at the beginning of the time record.
Cross channel ±0.5 deg. (DC to 51.2 kHz)
±1.0 deg. (DC to 102.4 kHz)
(transfer function measurement, both inputs on the same input range, vector averaged)
