13.9. Channels

13.9.1. Introduction to Channels

Channels are graphical representations

in a chart of measured data. Each

channel consists of a collection of series

with slightly different characteristics, for

example a Min, an Avg, and a Max

series.

A channel may consist of one or several

series of the following types:

Min Minimum value during a

period of time.

Avg Average value during a period

of time.

Max Maximum value during a

period of time.

Terms

Value A generic “value”. For a

Trend, this series normally

consists of Half-Cycle values.

For a Waveform channel,

these series consists of normal

(LF) waveform samples.

Example 1. This channel contains Min, Avg and

Max series plus two threshold series (dashed)

Example 2. This channel contains Min, Avg and

Max series and a Value series (Half-Cycle

RMS).

Example 3. This channel contains a Value series

(LF-sampling) and a HF series.

HF For a waveform channel, this series may contain High Frequency

samples.

HiHiLim

A trigger threshold - very high limit value

HiLim A trigger threshold - high limit value

LoLim A trigger threshold - low limit value

LoLoLim

A trigger threshold - very low limit value

There are three main types of channels in Dran-View, measured channels which

originate from the instrument, calculated channels which are generated by the

Harmonics/Timeplot Calculator (Enterprise Edition only), DFT calculations or

other means within Dran-View, and math channels (Enterprise Edition only) which

are user-defined channels derived from a mathematical formula.

When plotting a channel, the individual series can be enabled/disabled.
