MISC TAB
In the MISC tab, configuration of miscellaneous functions is
available (see Figure 34).
Two sets of registers are on the ADAR1000 device to control
the LNA and PA bias outputs and to set the DACs when the
corresponding bias outputs are in the on and off states. The register
values can be entered in the
Bias ON and Bias OFF sections.
Each set of register values is transferred to the ADAR1000-
EVALZ when the respective
Write Bias Values
buttons are clicked.
Under the Enables section, if the BIAS CTRL check box is
cleared, the bias digital-to-analog converter (DAC) outputs use
the
Bias ON register values only.
If the BIAS CTRL check box is selected while the device is in
receive mode, the PA DACs use the Bias OFF register values,
and the LNA DAC uses the Bias ON register value. If the check
box is selected while the device is in transmit mode, the
opposite is true, and the PA DACs use the
Bias ON register
values, and the LNA DAC uses the Bias OFF register values.
In the ADC section, use the MUX SEL dropdown menu to
choose the temperature sensor or the power detector, one
through four, for analog to digital conversion.
Select ADC EN , CLK EN , and ST CONV and then click Write
ADC Values to initiate analog to digital conversion.
Click Read ADC Word to access the conversion result.
The Memory Control section allows setting or clearing the
corresponding bits in Register 0x038 for various memory
control functions.
