Table 1-2 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
