As for synchronization with radar, SPO-15 features a synchronization circuit on board 51, but it was designed for older radars such Sapfir-23. The principle of operation is the same as in older SPO-10, the receivers are blocked in rhythm with own radar's pulses. It cannot handle CW or HPRF signals

SPO-15 is tested for blocking with simulated signal generator at 500 KHz. HPRF of N019 is 160 KHz. To know what's going on we need to know how blanking signal at KJ1 line actually looks like at graph, and how does it relate to PRF.

MPRF is only 16-30 kHz!

L006 label on output line inside radar document, tells us that radar was designed with SPO-15 in mind.

Okay one last question about SPO other then if 16-30 kHz MPRF really can’t he blanked 

The Su-27SK manual says with radar on you get front hemisphere warning and X category with strength of 5-8 signal strength. 
 

The one MiG-29 manual mentioning radar interfering SPO says it causes “chaotic” readings. 
 

Why is ours shut off then? I would think with 5-8 signal strength of X category, there is still possibility that a higher strength radar could become priority.
