Blanking), GPIB, Manual, or
Continuous.
Continuous (not in Random Repetitive Sampling mode) Internal, External
TTL (Rising or falling Edge), GPIB, or external Bus.
Trigger Modes
Manual
Single power value set to cover entire measurement dynamic range of sensor.
Auto
Automatically sets trigger level for signal over measurement dynamic range.
Nominal Internal Trigger
Bandwidth
N/A
Variable-auto set and manual
20 MHz, 2 MHz, 200 kHz, 20 kHz
Arming Sources
Sets the trigger arming, unless the
trigger source is set to EXTTTL
When ARMING is set to Blanking
ON, only samples taken when the
rear panel Digital Input BNC is
active will be averaged in the
measurement.

Trigger Point Display
(on-screen)
On-screen indicator/message
Trigger point depicted by trigger edge waveform (edge represents trigger
point of signal). Display position of trigger edge waveform adjustable.
