Description Characteristics
External direct trigger
metastability Metastability Reject on: Zero, typical
External direct trigger
real time accessory
interface Tekprobe-SMA, Levels 1 and 2. Hot switching is permitted on this real
time accessory interface.
External prescaled
trigger capabilities Prescaled triggering on signal applied to dedicated front panel
connector with Holdoff, Auto/Normal, Metastability Reject On/Off.
External prescaled trigger specifications apply only under the condition
that no other trigger source is applied to respective connectors.
Short term optimized mode and locked to internal 10 MHz reference
specifications only apply under the condition that there is no external
10 MHz reference applied to the front panel connector.
