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.

Frequency Range: 9 kHz to 3 GHz.
Frequency marker readout accuracy: ±(RE × MF + 0.001 × Span) Hz; RE = Reference Frequency Error, MF = Marker Frequency [Hz].

RF input.
RF Input Impedance: 50 Ω
RF VSWR (RF Attn = 20 dB), typical: < 1.2 (10 MHz to 3 GHz).
Maximum DC voltage: ±40 V (RF input).
Maximum safe input power: +33 dBm (RF input, 10 MHz to 3 GHz, RF Attn ≥ 20 dB).
Input RF attenuator: 0 dB to 51 dB (1 dB step).
Sweep speed Full span sweep speed, typical mean: 25.0 GHz/sec (RBW = 1 MHz), 24.7 GHz/sec (RBW = 100 kHz).

Amplitude and RF Flatness.
Reference level setting range: -170 dBm to +40 dBm, 0.1 dB step, (Standard RF input).

Noise and Distortion.
3rd Order IM intercept (TOI): +12 dBm at 2.130 GHz.
Displayed average noise level (DANL), Normalized to 1 Hz RBW, with log-average detector, Preamp on:
  500 kHz to 1 MHz -138 dBm/Hz;
  1 MHz to 25 MHz -153 dBm/Hz;
  >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.
A/D converter: 14 bits, 112 Ms/s.
Real-Time IF Acquisition Data: 112 Ms/s, 16-bit integer samples.

dBc (decibels relative to the carrier) is the power ratio of a signal to a carrier signal, expressed in decibels. If the dBc figure is positive, then the relative signal strength is greater than the carrier signal strength. If the dBc figure is negative, then the relative signal strength is less than carrier signal strength.

Noise Density
Noise Density is the amount of noise within a defined bandwidth, usually normalized to 1 Hz.

Spurious Signals
Spurious signals are undesired signals. They can be considered in two classes. They can be stationary; their frequency and amplitude do not change significantly, or non-stationary, where the frequency and/or amplitude change significantly over short time periods.
