External Triggering

In external trigger mode, the instrument accepts a hardware trigger at the front panel Ext Trig connector. The
instrument initiates one sweep or burst each time Ext Trig receives a TTL pulse with the specified edge. The external
trigger mode is like the manual trigger mode except that you apply the trigger to the Ext Trig connector.
See Trigger Input Signal, below.
Front Panel Operations
Press [Trigger] > Source External.
To specify whether the instrument triggers on a rising or falling edge, press Trigger Setup and select the edge
direction by pressing Slope.
SCPI Command
TRIGger:SOURce EXTernal
TRIGger[1|2]:SLOPe {POSitive|NEGative}

Software (Bus) Triggering

Available only from remote interface, this is similar to manual trigger mode from the front panel, but you trigger the
instrument with a bus trigger command. The instrument initiates one sweep or outputs one burst each time a bus
trigger command is received. The key blinks when a bus trigger command is received.
To select the bus trigger source, send TRIGger:SOURce BUS.
To trigger instrument from remote interface (USB, or LAN) when Bus source is selected, send TRIG or *TRG (trigger).
The front panel [Trigger] key is illuminated when the instrument is waiting for a bus trigger.
Front Panel Operations
Press [Trigger] > Source Manual.

Timer Triggering

The timer trigger mode issues triggers a fixed period apart. To select the bus trigger source, send TRIGger:SOURce
TIMer.
Front Panel Operations
Press [Trigger] > Source Timer.

Trigger Input Signal

This front panel connector is used in the following modes:
– Triggered Sweep Mode: Press [Trigger] > Trigger Setup > Source External, or execute TRIG:SOUR EXT (sweep must
be enabled). When a level transition of the correct polarity is received on the Ext Trig connector, instrument outputs
a single sweep.
