Comprehensive measuring system K2-38 (K238, K-2-38, K 2 38, K-238, K 238)
Comprehensive measuring system K2-38 provides a complete verification of measuring instruments FM modulation parameters. Can be used as a low-noise 50 MHz frequency multiplier with multiplicity and multiplication 5,10,20 source of high-quality FM signals with low distortion and frequency noise.
While checking modulation meters one unit K2-38 to replace the 30 units required for testing under existing procedures.
