20 automatic pulse parameter measurements
The U2042/44/49/63 and L2061/62/63 X-Series peak and average power sensor offers
simultaneous pulse parameter characterization of up to 20 pulses within a single capture.
Individual pulse duration, period, duty cycle, rise time, fall time and other pulse parameters
can be queried through the following SCPI codes: TRACe:MEASurement:PULSe[1-20], and
TRACe:MEASurement:TRANsition[1-20].
Together with a system’s rise time and fall time of 100 ns and video bandwidth of 5 MHz, the
X-Series peak and average power sensor enables a minimum measurable pulse width of 250 ns
with its sampling interval of 50 ns. Users can quickly and accurately measure the output power
and pulse parameters of pulses for radar pulse component design or manufacturing.

Auto burst detection
Auto burst detection helps the measurement setup of the trace of gate positions and sizes. This
feature also helps set up triggering parameters on a large variety of complex modulated signals
by synchronizing to the RF bursts. After a successful auto-scaling, the triggering parameters,
such as trigger level, delay and hold-off, are automatically adjusted for optimum operation. The
trace settings are also adjusted to align the RF burst to the center of the trace display.
