5903-HST High Speed Reverberation Tuner - Up to 100 RPM
Model 5903-HST High Speed Reverberation Tuner
The 5903-HST is a next-generation high-speed reverb tuner capable of continuous rotation speeds up to 100 RPM, dramatically outpacing traditional tuners to reduce test cycle times and increase chamber throughput. By enabling faster field stirring, it allows EMC labs to capture more samples per second, maximising normalised field strength, minimising input power requirements, and reducing measurement uncertainty.
Supporting both stepped (tuned) and continuous (stirred) mode operations, the 5903-HST complements the 5902-STD Standard Speed Tuner (2–16 RPM) and 5904-SST Slow Speed Tuner (0.1–5.8 RPM). Its durable, low-maintenance design features built-in safety measures including a protective tuner web and integrated chamber interlocks. Low-noise, low-vibration, RF-quiet operation makes it suitable for immunity, emission, and shielding effectiveness testing.
