CrySrcMwGenerator

FESA class for controlling MW generator for ECRIS ion source. Used for setting amplitude (0-9 V) and frequency (9-10.5 GHz) to MW generator. Actual values of amplitude and frequency can be aquired as well. Read ADC voltage for amplitude can take values from 0 to 9 V. Read ADC voltage for frequency can take values from 1.7 to 1.98 Volt what shall corresponds 9-10.5 GHz. Hardware used is AdcDac card with 2 DAC for setting and 2 ADC channels for reading the values.

***Scales set frequency and sends it to ADC Card:

void setFreq(double FreqU);

***Reads a set value from DAC (raw Hex) for amplitude and scales it to Volts:

double getDacValueAmpl();

***Reads a set value from DAC (raw Hex) for frequency and scales it to Volts:

double getDacValueFreq();

***Reads an actual amplitude value from ADC (raw Hex) and scales it to Volts:

double readActAmpl();
