A very nice and compact attenuator. Works as advertised and a great addition to the RF instrumentation in my lab. Delivery was on time and the product offered at a good price point. Another reviewer posted in-depth, valid test data from his spectrum analyzer, so no need to repeat such.I included a look inside pic for the curious minded.

This product works well. It is small and compact, and the attenuation switches track per the numbers on the unit. Very nice product for the price.

Used to set signal levels into SDR. Previous attenuator only achieved 50 Db. This one achieves 90 Db.
