Satellite Transponder Monitor stm3G

Selective RF-Power Meter 50MHz – 3GHz

The stm3G is a high-performance, compact and rack-mountable selective RF power monitoring unit, specifically developed for monitoring the power levels of individual satellite transponders in 3GHz and in the L-band range. Based on the proven hardware design of the RF-Design PwrM3G, this enhanced version adds the capability for precise, selective power tracking of defined carrier frequencies.
