Channel Power Setup Dialog
Channel Power measures the power and power spectral density in the channel bandwidth that you specify in
the following dialogs:
Channel Power Tab Channel BW: Sets the bandwidth over which the measurement
is made. This is typically larger than the actual signal
bandwidth.
Range: 1 Hz to 8 GHz in steps of 1 Hz
Default: 5 MHz
Method: Currently not available.
RRC Filter: This is used to turn the root-raised-cosine filter
(RRC) On or Off.
Rolloff Factor: Sets the roll-off factor for the measurement
(RRC filter must be on).
Range: 0.1 to 1.0 in steps of 0.01
Default: 0.22.
Symbol Rate: Sets the symbol rate for the measurement (RRC
filter must be on).
Range: 1 Hz to 8 GHz in steps of 1 Hz
Default: 3.84 MHz.
Advanced Tab /Hz: Toggles the result display between dBm or
dBm/Hz. The measurement type must be set to Abs before the
/Hz can be toggled on.
Type: Toggles between an absolute or relative measurement.
Noise Compensation: When noise compensation is toggled
on, a noise floor measurement is subtracted from the channel
power.
FFT: Toggles between FFT or Swept modes.
Start Time: Sets the start of the measurement relative to a
triggered event (currently not available).
Stop Time: Sets the stop time of the measurement relative to a
triggered event (currently not available).
