4-5 :FETCh Subsystem Spectrum Analyzer Commands
4-26 PN: 10580-00319 Rev. N S412E PM
:FETCh:CHPower?
Title: Fetch Channel Power/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.
Default Unit: Current amplitude units
Related Command: :FETCh:CHPower:CHPower?
:FETCh:CHPower:DENSity?
:FETCh:OBWidth:FREQuency?
Title: Fetch Occupied Bandwidth Frequency
Description: Returns the most recent occupied bandwidth lower frequency and upper
frequency.
Data is returned as 2 comma-separated values: lower frequency and
upper frequency in Hz.
Default Unit: Hz
Related Command: :FETCh:CHPower?
:FETCh:CHPower:CHPower?
: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.
Data is returned as 3 comma-separated values: occupied bandwidth,
percent of power, dB down.
Default Unit: OBW in Hz, Percent of Power in %, dB Down in dB
