Pulse width limits :
In Free Run and Triggered modes, the pulse width has a minimum resolution of 1 µsec and must be
specified as an integer, in dynamic pulse mode the minimum width is 0.1µs. If the value entered does not
meet these requirements, an alert will appear when attempting to generate a pulsed RF signal (
Click to dismiss the alert, then adjust the pulse width to a legal value and click Run Pulse again.
Note:
Due to the requirement to specify an integer value times fractions of a millisecond should be
specified in micro seconds, i.e 1500 µsec instead of 1.5msec

Pulse rate limit :
With Pulse Source set to Square, the Pulse Rate must be specified with a value such that the calculated
pulse width is a multiple of 1 µSec. If the value entered would result in an illegal pulse width, an alert will
appear when attempting to generate the RF signal (
Fig 3.7.7
). Click OK to dismiss the alert, and the pulse
rate will be automatically adjusted to the nearest legal frequency.
