I1 In the HP 83623A/24A, specification applies at ALC levels 0 dBm and above, and over the 20 to 55’C temperature range. Specification degrades 5 dB below 20°C, and 1 dB per dB below ALC level 0 dBm in those models.

I2 Option 002 adds 30 ns delay and zt5 ns pulse compression for external pulse inputs.
