Start With Problem/Need, Choose Best Tool

Swept Spectrum Analyzer (especially with digital IF)

• Familiar meas, user interface; compatible with established std’s, practices

• Frequency flexibility including span, RBW, VBW

• Maximum accuracy, dynamic range, sensitivity

• Measurement flexibility: phase noise, noise figure, ACPR, EMI, apps, etc.

Real Time Analyzer

• Find elusive signals, some ability to characterize (spectrogram, PVT)

• Spot unknown signals, signal behavior

• Monitor spectrum, trigger on spectral behavior

Vector Signal Analyzer (VSA software on signal analyzer platform)

• Detailed vector analysis and demodulation

• Signal capture, flexible playback

• Post-processing for signal selection, re-use

• Single user interface for multiple hardware platforms, multi-channel
