Discover Jammer Tester
The Protection Jammer Tester (PJT) is used for testing the functioning of Radio Frequency (RF) jammer systems.
Its simple design and intuitive operation enable users to quickly and efficiently verify whether the tested active, reactive, or hybrid jammer system is functioning as intended. The functional tests address two key questions:
- Are the frequencies programmed into the jammer system being effectively jammed?
- Is the emitted power from the jammer within expected parameters?
This streamlined and reproducible verification process eliminates the need for manual evaluation of measurement results using spectrum analyzers, along with the often complex interpretation that accompanies them.

Use cases
The Protection Jammer Tester has been designed according to standard military specifications.
It is suitable for outdoor use and operation in harsh conditions.
Why choose Spherea’s PJT?
