Making Measurements

Setting the low-latency external trigger mode

Setting the low-latency external trigger mode
In the low-latency external trigger mode, variations in delay time between the reception of
a trigger and the start of a one-point measurement are decreased for point trigger
measurement by using trigger pulses supplied to the external trigger input terminal. In
addition, using this mode will allow you to decrease the variations in the time required to
be ready for the next measurement trigger after execution of a one-point measurement.
This mode allows you to perform continuous point trigger measurement in sync with
external trigger pulses and accurately set a trigger delay time at each point-trigger point.
NOTE
The time required for measurement at each measurement point varies depending on the
settings of the E5070B/E5071B and the type of measurement. For more information, see
"External trigger delay time and point trigger interval" on page 247.
The low-latency external trigger mode becomes available by turning on the point trigger
function and setting the trigger source to "External."

NOTE If the trigger source is not the external trigger, the low-latency external trigger mode does
not work if it is specified to ON.
The setting of the low-latency external trigger mode is valid for all channels.

Procedure to set the low-latency external trigger

1. Setting the low-latency external trigger
If the trigger source is set to "External" and the trigger event to "On" (On Point), set the
low-latency external trigger mode.
Step 1. Press
Step 2. Press
Softkey
ON
OFF
2. Setting the external trigger delay time
Set the external trigger delay time at each point. The setting resolution is 10 μs.
