– Triggered Burst Mode: Press [Trigger] >Trigger Setup > Source External, or execute TRIG:SOUR EXT (burst must
be enabled). The instrument outputs a waveform with specified number of cycles (burst count) each time a trigger is
received from the specified trigger source.
– External Gated Burst Mode: Press the Gated softkey or execute BURS:MODE GAT with burst enabled. When
external gate signal is true, instrument outputs a continuous waveform. When external gate signal goes false, the
current waveform cycle completes and then instrument stops while remaining at voltage level corresponding to
starting burst phase. For noise, output stops as soon as the gate signal goes false.
Trigger Output Signal
The trigger output signal is chassis referenced. Use appropriate care not to touch the two signals simultaneously as
you are connecting or disconnecting these cables. De-energize connections to the instrument output before con-
necting or disconnecting these cables.
– A "trigger out" signal is provided on the front panel Sync Out connector (used with burst and sweep only). When
enabled, a pulse with either a rising edge (default) or falling edge is output from this connector at the beginning of
the sweep or burst.
– Internal (immediate) or Timer trigger source: Instrument outputs a square wave with a 50% duty cycle from the
Sync Out connector at the beginning of the sweep or burst. Waveform period equals specified sweep time or burst
period.
– External trigger source: Instrument disables "trigger out" signal.
– Bus (software) or manual trigger source: Instrument outputs a pulse (>1 μs pulse width) from Sync Out connector
at beginning of each sweep or burst.
Front Panel Operations
1. Enable sweep or burst.
2. Then press [Trigger] > Trig Out Setup.
