today at work i had to measure the receivers pulse signals
On the spectrum analyzer I set the center freq. to 418MHZ, at a span of 100K hz
The problem I don't understand is that the receiver sends four pulse signals at 410MHZ
What I don't get is that when you view it on the frequency analyzer each pulse is at a different DB lever because its sweep a span of frequency's
So it makes the receiver circuit look like the pulses are WEAK, but really they can't weak its because the frequency analyzer is sweeping a span of frequency
If the receiver is sending out 4 pulses at 418MHZ, how can i see/view it on the Frequency analyzer so each pulse has the same DB level?
I don't want it to be sweeping the frequency, I just want to make it FIXED at 418MHZ
