Analyzing device “Block A” is designed to work together with the radio receiver R-375 “Kaira”
and provides analysis of the spectrum of the received signal at the wideband output of the receiver in order to determine the spectrum of the signal of SSB telephone transmissions with frequency division multiplexing.
“R-375” (Kaira) – army VHF (MV / DMV) radio receiver. On the front panel, on the left, there is a two-speed vernier device with a photoscale of the MV range of 20-210 MHz, and on the right is the same UHF range of 210-500 MHz. Two antenna inputs – MV and UHF. There is an IF output of 4 MHz, a broadband (up to 400 KHz) low frequency output and an output to the TLF 0.3-2.5 KHz.
