External Puresignal Feedback Level Calculations
Based on calculations by WU2O
⚠
Do not exceed +13 dBm
at any rear panel input.
At 13 dBm or above, there is a possibility that the ANAN RF input could be damaged.
Inputs
Peak output power (Watts)
External coupling factor (dB)
Desired step attenuator setpoint (dB)
25dB is the optimal desired setpoint to ignore iternal cross talk.
Adjustment
7000/8000/G2
Changes the required input power offset used in the calculation. Note: The 7k/8k/G2 use a 14dB pre-amp before the ADC. All others use 20dB pre-amps.
