The SIGLENT SSA3000X, SSA3000X Plus and SVA1000X products are based on a similar swept superheterodyne spectrum analyser 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.
