STANFORD RESEARCH SYSTEMS SR770 100 kHz FFT Spectrum Analyzer w/source

The SRS SR770 is a single-channel 100 kHz FFT spectrum analyzer w/source with a dynamic range of 90 dB and a real-time bandwidth of 100 kHz. The speed and dynamic range of these instruments, coupled with their flexibility and many analysis modes, makes them the ideal choice for a variety of applications including acoustics, vibration, noise measurement and general electronic use. The SRS SR770 has a dynamic range of 90 dB. This means that for a full-scale input signal, the instruments have no spurious responses larger than -90 dBc (1 part in 30,000). Even signals as small as -114 dBc (1 part in 500,000) may be observed by using averaging. The low front-end noise and low harmonic distortion of the SRS SR770 allows you to see signals that would be buried in the noise of other analyzers. The SR770 includes a low-distortion (-80 dB), synthesized source which can be used to make frequency response measurements. It generates single frequency sine waves, two-tone signals for intermodulation distortion (IMD) testing, pink and white noise for audio and electronic applications, and frequency chirp for transfer function analysis. This direct digital synthesis (DDS) source provides an output level from 100 µV to 1 V, and delivers up to 50 mA of current. Specifications. Frequency Measurement range: 476 µHz to 100 kHz. Frequency Spans: 191 mHz to 100 kHz in a binary sequence. Center frequency: Anywhere within the 0 to 100 kHz measurement range. Frequency Accuracy: 25 ppm from 20 °C to 40 °C. Frequency Resolution: Span/400. Number of channels: 1. Input: Single-ended or differential. Input impedance: 1 M-ohm, 15 pF. Amplitude Full-scale input range: -60 dBV (1.0 mVp) to +34 dBV (50 Vp) in 2 dB steps. Dynamic range: 90 dB (typ.). Trigger Input Modes: Continuous, internal, external, TTL. Internal level: Adjustable to ±100 % of input scale. Positive or negative slope. Source Amplitude range: 0.1 mVp to 1.0 Vp. Amplitude resolution: 1 mVp (output >100 mVp), 0.1 mVp (output <100 mVp). DC offset: <10.0 mV (typ.).

Averaging is a mathematical process to reduce the variation in a measurement by summing the data points from multiple measurements and dividing by the number of points summed.

Jitter in technical terms is the deviation in or displacement of some aspect of the pulses in a high-frequency digital signal. Jitter is the time variation of a periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude, or phase of periodic signals. Jitter is a significant, and usually undesired, factor in the design of almost all communications links (e.g., USB, PCI-e, SATA, OC-48). In clock recovery applications it is called timing jitter.

Pulse Power
Pulse Power, the energy transfer rate is averaged over the pulse width. Pulse width is considered to be the time between the 50 percent risetime/falltime amplitude points. Pulse power averages out any aberrations in the pulse envelope such as overshoot or ringing.
