I use Keysight(earlier Agilent) signal source (E8257D PSG analog) for testing my circuits.
Though it also uses PLL circuit to synthesize the frequencies,but it is not affected by problems like
oscillator load pulling problems etc.
What's the order of reverse isolation(in dB) provided by the manufacturers to isolate their internal circuit
and prevent malfunctioning ,which may occur due to reverse leakage or dynamic load change at their output?
It should be a very high value,I have no idea and how do they achieve this in the design of their equipment?
