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

25dB is the optimal desired setpoint to ignore iternal cross talk.
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.

Results

Peak RF power
Coupler output level @ peak RF power
Required input power to step attenuator
Additional external attenuation required
Thresholds are near limit at ≥ 12.50 dBm, over limit at ≥ 13.00 dBm.
