Setting Up the Trigger and Making Measurements

Setting Up the Trigger and Making Measurements
The E5070B/E5071B has one trigger source. When this trigger source detects a trigger
signal that has occurred, a sweep is performed for channels in the "Initiate" state in the
order of channel 1 to channel 16. You set the "Initiate" or "Idle" status of each channel by
changing the trigger mode. For details on the trigger system, refer to Programmer's Guide.
NOTE
The execution of measurement for each channel does not depend on whether the channel is
displayed. Channels that have been activated can be measured even if they are not
displayed.
For each channel, a sweep is performed only for the stimulus ports needed to update the
parameters of the displayed trace.

Sweep Order in Each Channel

In a channel, each test port is set to a stimulus port in the order of port number and updates
each trace (Table 5-1).
Table 5-1 Sweep Order in Each Channel
Sweep Order
NOTE If full 2-, 3-, or 4-port error correction is in effect, no trace between calibrated ports is
updated until the last calibrated port is swept as the stimulus port.
Sweep is not executed for stimulus ports that are not required for updating traces.
