Spectrum Analyzer Commands :FETCh Subsystem
MS20xxC PM PN: 10580-00306 Rev. E 6-35
Fetch Channel Power Density
:FETCh:CHPower: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, then it does not return until the
sweep is complete. If the instrument is not sweeping, and if the current
data is not valid, then it returns error –230. This could occur if an *RST
command were issued immediately before the :FETCh?, or if a
measurement parameter were changed without an :INITiate.
Syntax: :FETCh:CHPower:DENSity?
Cmd Parameter: NA (query only)
Default Unit: Current amplitude units

Fetch Channel Power/Density
:FETCh:CHPower?
Description: This command returns the most recent channel power measurement
results: channel power and channel power density. If the instrument is
sweeping, then it does not return until the sweep is complete. If the
instrument is not sweeping, and if the current data is not valid, then it
returns error –230. This could occur if an *RST command were issued
immediately before the :FETCh?, or if a measurement parameter
were changed without an :INITiate.
Data is returned as 2 comma-separated values: channel power, channel
power density.
Syntax: :FETCh:CHPower?
Cmd Parameter: NA (query only)
Default Unit: Current amplitude units
