CALCulate Subsystem Commands
CALCulate[1|2|3|4|5|6]:THReshold:STATe ON|OFF|1|0
CALCulate[1|2|3|4|5|6]:THREshold:STATe?
Turns on the marker search threshold function. When this threshold function
is
CALCulate[1|2|3|4|5|6]:TPOWer[:DATA]?
Returns the total power of the specified trace. Trace A corresponds to
CALCulate1, trace B to CALCulate2, and so on. Corrections to the total power
are made for the slope and variation of the resolution bandwidth filter over the
wavelength range of the trace. When the CALCulate:TPOWer:IRANge is
the total power is calculated over the upper and lower range limits; otherwise,
the total power is calculated over the entire trace. Sending this query when
the CALCulate:TPOWer:STATe is
CALCulate[1|2|3|4|5|6]:TPOWer:IRANge:LOWer <numeric_value>[M|UM|NM|A|HZ|KHZ|MHZ|GHZ|THZ]
CALCulate[1|2|3|4|5|6]:TPOWer:IRANge:LOWer?
Sets the lower X-axis limit for the total power integration range for all traces.
Setting this value when the CALCulate:TPOWer:IRANge[:STATe] is
automatically turn the CALCulate:TPOWer:IRANge[:STATe]
used for the total power integration is the same range used for the marker
search range, the trace mean range, and the wavelength range. Changing the
range with this command will change all four ranges.
Default units for the parameter are meters. Sending the command when the
instrument is in a zero span will generate a "Settings conflict" error.
