Motorola R2024D/HS (High Stability) Secure Net System analyzer.

FEATURES ARE: Securenet multi Key option, is installed. It will test DES, 
DES/XL, DVP, DVP Code 2, and DVP/XL. It will encrypt and decrypt Securenet, 
on the air or through wire lines. Tests Secure deviation, eye pattern for 
jitter, simplex and full duplex bit error rates, end of message generation, 
encrypted 1 KC test tone. Any SecureNet base / repeater, mobile, portable, 
Console Interface Unit, Digitac, Securenet SpectraTac, and DVP modems can 
be thoroughly tested. Hybrids for the listed algorithms, are included. High 
stability oscillator option installed. IEEE-488 option included.
