Hand-held Analyzer Types 2250 and 2270 – User Manual

However, if you choose to annotate the profile during the measurement, the Annotations icon

will appear below the profile, not

as a paperclip icon in the Status Field or attached to a project

in Explorer, as described previously. In this case, you view the annotation using the method

described in section 11.3.1.

11.2.2 Recording the Signal

You can record the input signal during the measurement

by pressing the Manual Event

pushbutton (Manual Event marker), the Back-erase pushbutton (Exclude Marker) or when the

level of a specific parameter exceeds a certain level – or you can record the signal through the

whole measurement – depending on the Signal Recording setting on the Setup screen – details

in Chapter 12.

11.3 Displaying the Results

The Logging Measurement screen (or Profile view) includes three tabs at the bottom: Profile,

Spectrum and Broadband view (the Logging SLM includes the tabs: Profile, Broadband and

XL View). The tabs allow you to choose different ways of displaying the measurement results.

All but the Profile tab have been covered previously in Chapters 3 and 10, however a quick

recap is provided below.

The Broadband view shows an instantaneous L

readout, with associated bar graph and a

number of measurement parameters. (The first measurement parameter is displayed in a larger

font size for better readability.)

The XL View increases the size of the first parameter readout to a 4-digit, full-screen display

(including decimal point).

The Spectrum view shows two different spectra parameters being measured simultaneously.

11.3.1 The Profile View

The Profile view displays a profile of a logged broadband parameter (dB versus time). This is

very convenient when marking sound categories on-line or annotating the measurement (Fig.11.3).
