Measuring set '' P-322 ''.

Instruments for adjusting and controlling the PTA.Measuring set "P-322" was produced presumably since 1975. The measuring set is designed for tuning and operational measurements of PM channels, group and linear paths of multichannel telecommunication equipment, as well as its individual nodes in the range up to 300 kHz. The complex includes a signal generator "GS-300" and a selective level meter "SIU-300". The GS-300 generator was produced in two versions of a digital scale.
