<h3>2: Various options</h3>
These buttons control the local DSP auto correction options:
![Test source input plugin GUI 2](../../../doc/img/TestSourceInput_plugin_2.png)
<h4>2.1: Auto corrections</h4>
This combo box control the local DSP auto correction options:
- **None**: no correction
- **DC**: auto remove DC component
- **IQ**: auto make I/Q balance. The DC correction must be enabled for this to be effective.
- **DC+IQ**: auto remove DC component and correct I/Q balance.
<h3>3: Carrier shift from center frequency</h3>
Use this control to set the offset of the carrier from the center frequency of reception.
<h3>4: Decimation factor</h3>
<h4>2.2: Decimation factor</h4>
The I/Q stream from the generator is doensampled by a power of two before being sent to the passband. Possible values are increasing powers of two: 1 (no decimation), 2, 4, 8, 16, 32. This exercises the decimation chain.
<h3>5: Baseband center frequency position relative the center frequency</h3>
This exercises the decimation chain.
<h4>2.3: Baseband center frequency position relative the center frequency</h4>

- **Inf**: the decimation operation takes place around the center of the lower half of the BladeRF Rx passband.
- **Sup**: the decimation operation takes place around the center of the upper half of the BladeRF Rx passband.

<h3>8: Amplitude coarse control</h3>
<h3>3: Sample rate</h3>
This slider controls the number of amplitude bits by steps of 100 bits.
This controls the generator sample rate in samples per second.
<h3>9: Number of amplitude bits</h3>
<h3>4: Modulation</h4>
This is the signal peak amplitude in number of bits
- **No**: No modulation
- **AM**: Amplitude modulation (AM)
- **FM**: Frequency modulation (FM)
<h3>5: Modulating tone frequency</h3>
This controls the modulating tone frequency in kHz in 10 Hz steps.
<h3>6: Carrier shift from center frequency</h3>
Use this control to set the offset of the carrier from the center frequency of reception.
<h3>7: AM modulation factor</h3>
This controls the AM modulation factor from 0 to 99%
<h3>8: FM deviation</h3>
This controls the frequency modulation deviation in kHz in 100 Hz steps. It cannot exceed the sample rate.
<h3>9: Amplitude coarse control</h3>
This slider controls the number of amplitude bits by steps of 100 bits. The total number of amplitude bits appear on the right.
<h3>10: Amplitude fine control</h3>
This slider controls the number of amplitude bits by steps of 1 bit.
This slider controls the number of amplitude bits by steps of 1 bit. The signal power in dB relative to the maximum power (full bit range) appear on the right.
<h3>11: Signal power</h3>
This is the signal power in dB relative to the maximum power (full bit range).

Use this slider to give a DC component in percentage of maximum amplitude.
<h3>13: I bias</h3>
<h3>12: I bias</h3>
Use this slider to give an in-phase (I) bias in percentage of maximum amplitude.
<h3>14: Q bias</h3>
<h3>13: Q bias</h3>
Use this slider to give an quadrature-phase (Q) bias in percentage of maximum amplitude.
<h3>14: Phase imbalance</h3>
Use this slider to introduce a phase imbalance in percentage of full period (continuous wave) or percentage of I signal injected in Q (AM, FM).
