LEVEL SETTING TIME
Electronic attenuator (Option 003) is assumed in all cases. ALC loop bandwidth
‘Moderate’ or ‘Broad’, to be within ≤0.3 dB.
Level setting time (non list
mode):
After receipt of GPIB interface delimiter (terminator), 23°C ±5°C
< 4.5 ms, typically 2.5 ms
Level setting time (Option 10 list
mode):
After external trigger in list mode, 23°C ±5°C
< 3 ms, typically 1.5 ms
