Latency is defined as the delay between the applied RF crossing the trigger level and the meter
switching into the triggered state.
External trigger range High > 2.0 V, Low < 0.8 V; BNC connector; rising or falling edge triggered; input
impedance > 1 kW
Trigger out Output provides TTL compatible levels (high > 2.4 V, low < 0.4 V) and uses a BNC
connector
1 Fast speed is not available for 8480 and N8480 series sensors.
2 Maximum measurement speed is obtained by using binary output in free run trigger.
3 For E9320 sensors, maximum speed is achieved using binary output in free run acquisition.
