Its external appearance is remarkably similar to the just-announced SVA1015X SA/VNA, but the internals are somewhat different. So that’s where we start.įigure 2: Siglent introduced the SSA3021X spectrum analyzer in 2016.

Conveniently, Jones tore down that earlier instrument as well. But, as a processor sort of guy, I’m going to focus on the digital design of this instrument because it reveals the evolution in Siglent’s design approach when compared to the design of the SSA3021X spectrum analyzer that Siglent introduced back in 2016. The SVA1015X hides a lot of RF engineering under its hood. There’s another $2K or so of software-enabled options available beyond that.įigure 1: Siglent recently introduced the low-cost SVA1015X spectrum analyzer/vector network analyzer.

Add $609 to that price and you get the VNA option. The Siglent SVA1015X SA/VNA sells for $1395, configured as an SA. Recently, Jones posted a 1-hour (!) teardown video of the new Siglent SVA1015X, which is a low-cost, combo spectrum analyzer (SA) and vector network analyzer (VNA). Something might be gaining on you.” – Satchell Pageĭave Jones, the multitalented proprietor of has posted more than 1100 online videos covering all aspects of electronics, including numerous teardown videos that I used frequently in a prior life to highlight certain revealed design aspects in the equipment he’s torn down.
