Gate Positioning Parameters

Most control settings are determined by two key parameters of the

signal under test: the pulse repetition interval (PRI) and the pulse

width (τ). If you know these parameters, you can begin by picking some

standard settings. Table and Table summarize the parameters for a

signal whose trigger event occurs at the same time as the beginning of

the pulse (for example, SD is 0). If your signal has a non-zero delay, just

add it to the recommended gate delay.

Signal Delay

Pulse width (τ)

When using the short gate delays, you may notice the gate delay time jitter by ±1 µs. This jitter is due to the

spectrum analyzer 1 MHz gate clock, and it does not indicate a problem.
