(Specifications are subject to change without notice)
PULSE MODE OPERATION
Acquisition Mode:
Discontinuous triggered sample acquisition
Trace Display:
Power versus time swept trace (rolled trace for slow timebases)
Trace Averaging:
1 to 16384 samples per sweep data point, exponential
Markers (vertical cursors):
Settable in time relative to the trigger position. Marker time position is
limited to displayed trace interval.
For each marker independently:
Average, minimum and peak power at a single time offset
For a pair of markers: Average, minimum and peak power over the interval between markers
Power ratio between markers
The following automatic measurements are selectable in the power versus time (Pulse) mode:
Pulse width Pulse rise-time
Pulse fall-time Pulse period
Pulse repetition frequency Pulse duty cycle
Pulse off-time Peak power
Pulse ―on‖ power dB or Percent overshoot
Waveform Average power IEEE Top level power
IEEE Bottom level power Edge skew (Model 4542 only)
Edge delay
MODULATED MODE OPERATION
Acquisition Mode:
Continuous (untriggered) sample acquisition
Trace Display:
Power versus time rolled trace
Signal Filtering:
―Sliding window‖ filter; 0.002 to 16.0 seconds (fixed) or auto-filter
Channel Math:
Displays the ratio, sum (power sensors) or difference (voltage sensors)
between channels or between a channel and a reference measurement
The following automatic measurements are performed continuously in Modulated Mode:
Filtered average power
Peak power
Minimum power
Peak to Average ratio
Dynamic range
