Each measurement has help text and graphics associated with it that help explain how

the measurement is made.

Waveform histograms show visually how waveforms vary over time.

Horizontal waveform histograms are especially useful for gaining insight

into how much jitter is on a clock signal, and what the distribution of that

jitter is. Vertical histograms are especially useful for gaining insight into how

much noise is on a signal, and what the distribution of that noise is.

Measurements taken on a waveform histogram provide analytical

information about the distribution of a waveform histogram, providing

insight into just how broad a distribution is, the amount of standard

deviation, the mean value, etc.

time. Included are numeric measurements made on the waveform histogram data.

Video design and development (Optional) – Many video engineers have

remained loyal to analog oscilloscopes, believing the intensity gradations

on an analog display are the only way to see certain video waveform

details. The fast waveform capture rate, coupled with its intensity-graded

view of the signal, provides the same information-rich display as an analog

oscilloscope, but with much more detail and all the benefits of digital

scopes.

Standard features such as IRE and mV graticules, holdoff by fields, video

polarity, and an Autoset smart enough to detect video signals, make these

the easiest to use oscilloscopes on the market for video applications. And

with high bandwidth and four analog inputs, the oscilloscope provides

ample performance for analog and digital video use.

The video functionality is further extended with an optional video application

module, which provides the industry's most complete suite of HDTV and

custom (nonstandard) video triggers, as well as a video picture mode

enabling you to see the picture of the video signal you are viewing - for

NTSC and PAL signals. The optional video analysis functionality is offered

free for a 30- day trial period. This free trial period starts automatically when

the instrument is powered on for the first time.

brightness settings as well as manual controls.

Power analysis (Optional) – Ever increasing consumer demand for

longer battery-life devices and for green solutions that consume less power

require power-supply designers to characterize and minimize switching

losses to improve efficiency. In addition, the supply's power levels, output

purity, and harmonic feedback into the power line must be characterized to

comply with national and regional power quality standards. Historically,

making these and many other power measurements on an oscilloscope has

been a long, manual, and tedious process. The optional power analysis

tools greatly simplify these tasks, enabling quick and accurate analysis of

power quality, switching loss, harmonics, safe operating area (SOA),

modulation, ripple, and slew rate (di/dt, dv/dt). Completely integrated into

the oscilloscope, the power analysis tools provide automated, repeatable

power measurements with a touch of a button; no external PC or complex

software setup is required. The optional power analysis functionality is

offered free for a 30- day trial period. This free trial period starts

automatically when the instrument is powered on for the first time.
