Hello everyone, In the past there have been several posts about amplifier input and AGC. As many have pointed out this is always a bad idea since the AGC circuit tends to add phase noise, etc.
So my question today is: Is this still true? My old Panoramic spectrum analyzer (yeah, she's a beauty!) has a very nice input attenuator which you select manually. Is this my only option? Digital pots don't usually go above 1 MHz, and if they did, are they an option?
