Option Identification
Response is a list of all detectable options present in the instrument. When no options are present response is ASCII ‘0’:
<Prescaler option (if present)>, <Oscillator code>, <SW option>, <SW option>…
<Prescaler option> = 3GHz / 10Ghz / 15GHz / 20GHz / 24GHz.
<Prescaler option> represents maximum frequency that a user is allowed to measure using currently installed HW and SW license option.
<Oscillator code> = TCXO / OCXO30 / OCXO40.
