in tke primary cathode follower and connected directly to the receiving
antenna.
The 2 sicresecon’ delay line vee added to persit the leading edge
of the waveform to be recorded.
In order to establish a definite tine relationship between the reception of the signal and the triggering of a given device such as a
ecunter or trananitter, o tize parker pip, generated by the delay trigger
and from one of the oscilloscopes, is fed through the 2 sicrosecond delay
line and superiaposed on the initial portion of the received weveforn.

All ocecilloscopes ere calibrated against a known frequency standard
for eveep linearity.
The cathode follover triggering system is set to trigger approximately
6db. above the noise level.
