Holdoff Trigger Time Accuracy,
nominal
If Time Quali fi ed Trigger is used, the Accuracy value increases to 2X the number given
above for the speci fi ed trigger source.
External Trigger 1 Threshold Voltage,
nominal Variable: –2.5 V to +2.5 V settable
External Trigger 2 Threshold Voltage,
nominal Fixed: TTL
External Trigger 1 Threshold Voltage
Setting Resolution, nominal 0.01 V
External Trigger 1 Input Impedance,
nominal Selectable: 50 Ω or 5 k Ω
External Trigger 2 Input Impedance,
nominal Fixed: 10 k Ω
External Trigger 1 Minimum Pulse
Width (applies to 50
Ω Impedance
only), nominal
>5 ns
External Trigger 2 to External Trigger
1 Minimum Delay, nominal >20 ns
This is the time from the rising edge of the external gate signal to the rising edge of the
external trigger signal needed to guarantee a trigger will be accepted. This speci
fi cation
also applies from the falling edge of the external trigger signal to the falling edge of the
external gate signal.
External Trigger 1 Timing Uncertainty (50 Ω impedance only)
>80 MHz to 165 MHz acquisition
BW ±11 ns
>40 MHz to 80 MHz acquisition
BW ±13.5 ns
>20 MHz to 40 MHz acquisition
BW ±20 ns
