2.7.2 Curve ID Box<br />
Figure 2.7.2—Curve ID box<br />
The curve ID box provides you with much useful information<br />
about the curves. It has three main columns: #<br />
(curve number), SRC (source), and TYP (type).<br />
Number: This identifies the number of the relevant curve. The arrow to the<br />
right of these numbers indicates the current selected curve.<br />
Source: This identifies the amplitude of each curve.<br />
Type: The curve type is a little more complicated; each curve is identified by<br />
three letters.<br />
First letter:<br />
I = Intermodulation Distortion<br />
C = Composite<br />
P = Pure-tone<br />
D = Digital Speech<br />
F = Frequency Shift<br />
Second letter:<br />
For pure-tone:<br />
N = Normal pure-tone<br />
F = Fast pure-tone<br />
S = Short pure-tone<br />
For composite, digital speech, or Digital FS:<br />
W = Weighted composite<br />
F = Flat weighted<br />
S = Spectrum<br />
Third letter:<br />
P = SPL measurement<br />
G = Gain measurement<br />
% = Percent<br />
Note: When you toggle back and forth between Gain and SPL in the menu, all<br />
curves are converted to the new format, except for spectrum measurements made<br />
with the reference microphone turned off.<br />
Lastly, between the SRC and TYP columns, the <strong>FP35</strong> uses symbols to describe the<br />
display status of the curves.<br />
≡ Curve is completely on the graph<br />
• Curve is measured but turned off<br />
↓ Curve is partially off the bottom of the graph<br />
↑ Curve is partially off the top of the graph<br />
Curve is on, but is out of view above the graph<br />
Curve is on but is out of view below the graph<br />
Curve is partially off the graph in both directions
