(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
