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

July 25, 2018

Introduction

The SIGLENT SSA3000X, SSA3000X Plus and SVA1000X 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.

Additional SVA Features and Options

Still having trouble choosing?

Here are some additional features and options that are exclusive to the SSA PLUS and SVA platforms 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:

  • AM/FM modulation analysis (SVA1000X-AMA. SSA3000XP-AMA) enables visualization of data encoded using AM/FM
  • Digital modulation analysis (SVA1000X-DMA. SSA3000XP-DMA) enables visualization of data encoded using FSK/ASK
  • Advanced measurement kit (SVA1000X-AMK, SSA3000XP-AMK) feature Harmonic and CNR measurements in addition to CHP/ACPR/TOI/OBW/Monitor.
  • Mechanical calibration kit for VNA (F503ME)
