1
All measurements performed with a 50
Ω load unless stated otherwise. The PDA10DT has a 50 Ω
series terminator resistor (i.e., in series with amplifier output). This forms a voltage divider with any load
impedance (e.g., 50
Ω load divides signal in half).
2
Saturation of the output voltage may cause damage to the InGaAs detector element.
3
After the temperature has stabilized on all gain steps. Also note that the worst case offset is on the
10 dB gain step.
