65dB
Log linearity
Tunable to +/-1/3db
Temperature drift
<0.5dB after adjustment
Input voltage noise density
1.2nv/√Hz
Input current noise density
<1pa/√Hz
Risetime (10% to 90%)
8ns
With full dynamic range, faster with 2 log stages eliminated
Transit time (50% to50%)
8ns
Variation in transit time over full dynamic range can be tuned to <2ns
Pulse to CW variation
<.0.2dB
A change in pulse duration from 10 ns to 1 ms (at high duty-cycle) does not affect pulse height for DC coupled designs. For pseudo AC coupled designs 90%+ duty cycles are possible.
