<h3>6. Amplitude adjustment</h3>
This slider lets you adjust the amplitude scale. The full scale value appears on the left of the slider. The unit depends on the projection.
The amplitude range (vertical scale) can be set to any value from 1e-10 to 9.999e+10. Values are entered as mantissa (6.3 and 6.4) and exponent (6.5) values.
I/Q signal range is +/-1 however values larger than 1 are accomodated for the general usage of the scope in other plugins.
When displayed signal can be negative (+/- scale) the range is -range to +range. When displayed signal is positive (ex: magnitudes) the range is 0 to 2&times;range.

<h4>6.1. Amplitude scale reset</h4>
Push this button to reset amplitude scale to 1.
<h4>6.2. Mantissa display</h4>
The amplitude range is M&times;10<sup>E</sup>. This displays the M value.
<h4>6.3 Mantissa fine control</h4>
This slider sets the decimal digits of the mantissa from .000 to .999
<h4>6.4 Mantissa coarse control</h4>
This dial button sets the integer part of the mantissa from 1 to 9.
<h4>6.5 Exponent control</h4>
This slider sets the exponent from -10 to +10. The value is displayed at the left of the slider in exponent notation.
<h4>6.6 Unit multiplier on vertical scale</h4>
This displays the unit multiplier for values on the vertical scale of the display.
- **p**: pico (&times;10<sup>-12</sup>)
- **n**: nano (&times;10<sup>-9</sup>)
- **&mu;**: micro (&times;10<sup>-6</sup>)
- **m**: milli (&times;10<sup>-3</sup>)
- **-**: none (&times;1)
- **k**: kilo (&times;10<sup>3</sup>)
- **M**: mega (&times;10<sup>6</sup>)
- **G**: giga (&times;10<sup>9</sup>)
<h3>7. Offset adjustment</h3>
This pair of sliders let you offset the trace vertically. The offset value from reference appears on the left of the slider. The reference is either:
The amplitude range can be offset by any value from -5&times;10<sup>-10</sup> to 5&times;10<sup>10</sup>.
- central zero value for Real, Imag, Phi and dPhi projections
- bottom zero value for MagLin projection
- bottom -200 dB value for MagDB projection
I/Q signal range is +/-1 however values larger than 1 are accomodated for the general usage of the scope in other plugins.
The top slider is a coarse adjustment. Each step moves the trace by an amount that depends on the projection type:
![Channel Analyzer NG plugin amplitude offset control](../../../doc/img/ChAnalyzerNG_plugin_ampOffset.png)
- Real, Imag: 0.01
- Mag: 0.005
- MagSq: 0.005
- MagDB: 1 dB
- Phi, dPhi: 0.01
<h4>7.1. Amplitude offset reset</h4>
The bottom slider is a fine adjustment. Each step moves the trace by an amount that depends on the projection type:
Push this button to reset amplitude offset to 0.
- Real, Imag: 50.0E-6
- Mag: 25.0sE-6
- MagSq: 25.0sE-6
- MagDB: 0.01 dB
- Phi, dPhi: 50.0E-6
<h4>7.2. Mantissa display</h4>
The amplitude offset is M&times;10<sup>E</sup>. This displays the M value.
<h4>7.3 Mantissa fine control</h4>
This slider sets the decimal digits of the mantissa from .000 to 0.999 and jump to next unit (so 5.000 can be reached)
<h4>7.4 Mantissa coarse control</h4>
This dial button sets the integer part of the mantissa from -5 to 4.
<h4>7.5 Exponent control</h4>
This slider sets the exponent from -10 to +10. The value is displayed at the left of the slider in exponent notation.
