Auto burst detection
Auto burst detection helps the measurement setup of the trace or gate positions and sizes,
and 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 the 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.
20-pulse measurements
The U2040 X-Series can measure up to 20 pulses. The measurement of radar pulse timing
characteristics is greatly simplified and accelerated by performing analysis simultaneously
on up to 20 pulses within a single capture. Individual pulse duration, period, duty cycle and
separation, positive or negative transition duration, and time (relative to the delayed trigger
point) are measured.
High average count reset
When high averaging factors have been set, any rapid adjustments to the amplitude of the
measured signal will be delayed due to the need to allow the averaging filter to fill before a
new measurement can be taken at a stable power level. The U2040 X-Series allows you to
reset the long filter after the final adjustment to the signal’s amplitude has been made.
Built-in radar and wireless presets
The U2040 X-Series provides built-in radar and wireless presets for common signals such
as DME, GSM, EDGE, WCDMA, WLAN, and LTE.
