Test Setup For Option; Pulse Generator Test Setup Settings - HP 8590 E-Series User Manual

The following example demonstrates the rules for setting up a time-gated measurement. In this
example, we are using two signal generators to generate two signals at the same frequency
(50 MHz). The pulse generators "space" (interleave) the signals in time as well as pulse
modulate the signals.
