Agilent Technologies N9340A manual Log Pwr, Voltage

Key Reference 5

Log Pwr

Averages the data as appropriate for the logarithmic scaled y axis.

When average type is set to Log Pwr, “LgAv” appears on the left side of the display.

Key access: [BW/SWP] > {Avg Type}

Pwr

Converts the scale from logarithmic to linear power units, and then averages the power trace data.

With average type set to Pwr, “PAvg” appears on the left side of the display.

Key access: [BW/SWP] > {Avg Type}

Voltage

Averages the data as appropriate for the linearly scaled y- axis scale.

With average type set to Voltage, “VAvg” appears on the left side of the display.

Key access: [BW/SWP] > {Avg Type}

There are actually four types of averaging processes within an N9340A. All, except VBW filtering, are affected by this setting. They are listed as follows:

• Trace averaging

Averages signal amplitudes on a trace- to- trace basis. (Press Log Pwr or Pwr)

• Average detector

Averages signal amplitudes during the time or frequency interval represents the result as a single measurement point.

• Noise marker

Averages signal amplitudes across measurement points to reduce variations for noisy signals.

• VBW filtering

Performs a form of averaging of video signal.
