Select the Sweep tab to set Trace parameters and Sweep parameters.
Sweep Tab
Trace
In trace average, the number of traces to average is specified in the Average Count box. The resulting trace then shows a moving average over X number of sweeps. For instance if the average count is set to “10”, then trace average shows a moving average over 10 sweeps. The average is continuously updated as new sweep data is acquired.
Operation
• Normal: Displays data for the current trace sweep.
• Min Hold: Shows the cumulative minimum value of each display point over many trace sweeps.
• Max Hold: Shows the cumulative maximum value of each display point over many trace sweeps.
• Average: Shows an exponential average of a number of traces, determined by the number entered in Average Count.
• Rolling Max: Rolling max displays the max over a set number of sweeps. The number of sweeps is also specified in the average count box.
• Rolling Min: Rolling min displays the max over a set number of sweeps. The number of sweeps is also specified in the average count box.
Average Count
Sets the number of traces for use in calculating the average display value. The number used for averaging ranges from 1 to 65535.
Single/Continuous Sweep
In single sweep mode, after the sweep, the instrument waits in Hold mode until the Initiate button is pressed. Change the Sweep Type by selecting the radio button for Single or Continuous.
Sweep Modes
Two sweep modes are available on the instrument - FFT (default) or No FFT. Press the radio button for the desired Sweep Mode. Review the table below to help determine which mode to use for the current measurement.
