We now consider the simulated, newly constructed, aircraft display. Viewing the EGON guiding (rotating) signal blip, albeit - that this actual system did not concerned Nachtfee directly, though was maintained for navigating the aircraft towards the area where the flares had to be dropped over the target. The EGON signal prf differs only a single Hertz from the actual Nachtfee prf. But, the Nachtfee signals behaving in coherence within the Nachtfee system; as long as it is being monitored on the Nachtfee Consol LB 2 control crt screen (actually shown). That we still have to readjust sometimes is being cause that the simulated aircraft display (time-base signal) is derived from the Philips/Fluke PM 5193 synthesizer, thus is being based upon a quartz crystal; whereas our Nachtfee Console being based upon a Rb-standard, thus on some kind of atomic resonance.
