3.3.2.1 Analog to Digital Voltage
The AD VOLTAGES maintenance screen shows the current voltage levels sensed at the microcontroller’s
analog to digital inputs. There are too many input channels to show all voltages on one screen, so the
user is prompted to choose either 10 bit or 12 bit resolution voltages.
<1>10 BIT ADC VOLTAGES AD VOLTAGES
<2>12 BIT ADC VOLTAGES
There are four higher resolution (12 bit) channels that read values from the azimuth, elevation and
polarization sensors along with the higher resolution receiver channel. These values will be of more
interest during system calibration.
The eight lower resolution (10 bit) channels deal with other sensors such as the L-band power detector,
internal temperature sensor, etc.
3.3.2.1.1 10 Bit ADC Voltages
The 10 BIT ADC maintenance screen shows the current voltage levels sensed at the boardset’s eight 10
bit resolution analog to digital inputs. The voltage will be displayed in the 0.001 to 5.000 range. If the
microcontroller sees less than 0.001, it will display “UNDER”.
Next to the scaled voltage will be the current analog to digital "count" (0 to 1023).
