4540 Series Performance Specifications (continued)

(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
