Tracking error (measured relative to
value at unity gain) equals [V_O - V_O
(unity gain)] dB - V₂dBm

Rectifier input,
V₂ = +6dBm, V₁ = 0dB
V₂ = -30dBm, V₁ = 0dB
NOTES:
1. Input to V₁ and V₂ grounded.
2. Measured at 0dBm, 1kHz.
3. Expandor AC input change from no signal to 0dBm.
4. Relative to value at T_A = 25°C.
5. Electrical characteristics for the SA571 only are specified over -40 to +85°C temperature range.
6. 0dBm = 775mV_RMS.
