This set of commands returns the most recent measurement data of the active measurement. They will not switch to another measurement. To make a new measurement, use the INITiate command. To get new measurement data, use the READ or MEASure query commands.
Returns the amplitude at the given frequency. The command does not wait for the sweep to complete. If the trace data at the requested frequency is invalid (or out of span) then NAN is returned and error code -230 is indicated.
Parameters
<numeric_value> {HZ | KHZ | MHZ | GHZ}
:FETCh:CHPower?
Title
Fetch Channel Power and Density
Description
This command returns the most recent channel power measurement results: channel power and channel power density. If the instrument is sweeping, it will not return until the sweep is complete. If the instrument is not sweeping and the current data is not valid it will return error -230. This could occur if there was a *RST immediately before the :FETCh? or if a measurement parameter was changed without an :INITiate.Data is returned as 2 comma-separated values: channel power, channel power density.If the measurement is not enabled with [:SENSe]:CHPower:STATe then, the instrument will indicate error -400 and return the string "nan,nan"
:FETCh:CHPower:CHPower?
Title
Fetch Channel Power and Density
Description
Returns the most recent channel power measurement result. It returns only the channel power, not the channel power density. Use FETCh:CHPower? to get both channel power and channel power density.If the instrument is sweeping, it will not return until the sweep is complete. If the instrument is not sweeping and the current data is not valid it will return error -230.This could occur if there was a *RST immediately before the :FETCh? or if a measurement parameter was changed without an :INITiate.If the measurement is not enabled with [:SENSe]:CHPower:STATe then, the instrument will indicate error -400 and return the string "nan,nan".
:FETCh:CHPower:DENSity?
Title
Fetch Channel Power Density
Description
Returns the most recent channel power density measurement result. It returns only the channel power density, not the channel power. Use :FETCh:CHPower? to get both channel power and channel power density. If the instrument is sweeping, it will not return until the sweep is complete. If the instrument is not sweeping and the current data is not valid it will return error -230.This could occur if there was a *RST immediately before the :FETCh? or if a measurement parameter was changed without an :INITiate. If the measurement is not enabled with [:SENSe]:CHPower:STATe then, the instrument will indicate error -400 and return the string "nan,nan".
:FETCh:OBWidth?
Title
Fetch Occupied Bandwidth
Description
Returns the most recent occupied bandwidth measurement results: occupied bandwidth, percent of power and dB down. One of either percent of power or dB down is measured and the other is set. That is determined by the value set using [:SENSe]:OBWidth:METHod. If the instrument is sweeping, it will not return until the sweep is complete. If the instrument is not sweeping and the current data is not valid it will return error -230. This could occur if there was a *RST immediately before the :FETCh? or if a measurement parameter was changed without an :INITiate. If the measurement is not enabled with:SENSe:OBWidth:STATe then, the instrument will indicate error -400 and return the string "nan,nan,nan".
:FETCh:PEAK?
Title
Fetch Peak
Description
Returns a pair (amplitude, frequency in Hz) of the peak amplitude in the current sweep. The command does not wait for the sweep to complete. If the trace data is invalid then both numbers in the pair will be NAN and error code -230 will be indicated.
