TEKTRONIX RSA503A 3.0 GHz USB Spectrum Analyzer

The Tektronix RSA503A 3.0 GHz USB spectrum analyzer was built to bring real-time spectrum analysis to solving the problems of spectrum managers, interference hunters and network maintenance personnel who need to track down hard to find interferers, maintain RF networks and keep records of their efforts. The heart of the system is the USB-based RF spectrum analyzer that captures 40 MHz bandwidths with great fidelity in harsh environments.

  >25 MHz to 1 GHz -161 dBm/Hz;
  >1 GHz to 2 GHz -159 dBm/Hz;
  >2 GHz to 3 GHz -156 dBm/Hz.
Phase noise Offset / 1 GHz CF:
  10 kHz / -94 dBc/Hz;
  100 kHz / -94 dBc/Hz;
  1 MHz / -116 dBc/Hz.
Residual spurious response (Reference = -30 dBm, RBW = 1 kHz):
  <-75 dBm (500 kHz to 60 MHz), typical;
  < -85 dBm (>60 MHz to 80 MHz), typical;
  <-100 dBm (>80 MHz to 3.0 GHz), typical.
Spurious response with signal at half-IF: < 75 dBc, (CF: 30 MHz to 3 GHz, Ref = -30 dBm, Atten = 10 dB, RBW = 10 Hz, Span = 10 kHz) Signal frequency = 2310 MHz, RF input level = -30 dBm.

IF bandwidth: 40 MHz.

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.
