How do I pick the right spectrum analyzer for my application?

July 25, 2018

Introduction

The SIGLENT SSA3000X and SVA1015X products are based on a similar swept superheterodyne spectrum analyzer platform and have very similar starting prices. There are quite a few similarities, but also a few differences that could affect the end results for particular applications.

The table below compares the major specifications and the comparable options as they pertain to specific applications like VSWR.

SSA3000X SVA1015X
Spec An Frequency Range 9 kHz – 2.1 GHz (3.2 GHz model available) 9 kHz – 1.5 GHz
DANL -161 dBm/Hz -156 dBm/Hz
Min RBW 1 Hz 1 Hz
Total Amplitude Accuracy +/- 0.7 dB +/- 1.2  dB
Tracking Generator and Frequency Range 100 kHz – Max Frequency 5 MHz – Max Frequency
Demodulation AM/FM demod with audio output (Free) AM/FM demod with audio output (Free)
EMI Measurements Option EMI-SSA3000X (FCC RBWs, QP detector, -6 dB EMI filter) Option SVA1000X-EMI (FCC RBWs, QP detector, -6 dB EMI filter)
Broadcast Measurements Option AMK-SSA3000X (Channel power, Adjacent channel power ratio, Time domain power, Occupied bandwidth, Third-order intercept, Spectrum monitor) Option SVA1000X-AMK (Channel power, Adjacent channel power ratio, Time domain power, Occupied bandwidth, Third-order intercept, Spectrum monitor)
VSWR/Return Loss Measurement Option Refl-SSA3000X (Includes on-screen return loss, reflection coefficient, and VSWR measurements displayed)

NOTE: Requires return loss bridge hardware*

Currently has a 100 Hz minimum span

Option SVA1000X-VNA (On screen S11 with SWR graph)

NOTE: Currently has a 5 MHz minimum span

Option RBSSA3000X (Includes on-screen VSWR measurement AND return loss bridge hardware)

*Compatible with many commercially available return loss bridges/directional couplers

 

Additional SVA Features and Options

Still having trouble choosing?

Here are some additional features and options that are exclusive to the SVA platform that may help:

Free Features:

  • Touch screen control with shortcut widget
  • Mouse/Keyboard support
  • Easy web browser web control
  • Power-On-Line – Instrument will automatically restart when power is restored to the mains power connection (power cord) when this feature is enabled.

Additional Options:

  • Vector Network Analyzer (SVA1000X-SVA) adds S11 and S21 measurement capability with linear/log graphing, Smith, and polar charting of complex impedance and more
  • Distance-to-fault option (SVA1000X-DTF) ideal for fault and degradation testing cable assemblies
  • AM/FM modulation analysis (SVA1000X-AMA) enables visualization of data encoded using AM/FM
  • Digital modulation analysis (SVA1000X-DMA) enables visualization of data encoded using FSK/ASK
  • Mechanical calibration kit for VNA (F503ME)
