Adjusting the Trace Settings

The Trace menu is used to modify the existing predefined view, or create a
customized view. Window and Win State softkeys are used to modify layout of
view, the Data softkey is used to specify the displayed data results for the
current window. Please note only in User Defined measurement are all of the
data results from Spectrum measurement and Waveform measurement

Auto Trigger
annotated in the top left corner of the FieldFox screen.
If a valid trigger signal is not received before the specified Auto
Trig Time, a acquisition will occur automatically.
Enter 0 to set Auto Trigger OFF. When Auto Trigger is OFF, the
FieldFox does NOT perform an acquisition unless a valid
trigger signal is received.
(Default: 100 ms, minimum: 1 ms, maximum: 100s)
— Average Type Opens a menu of averaging softkeys.
Then select one of the following:
——Power (Linear) Averaging – Best for measuring true power
levels. Used in Noise Marker Average. Mathematically, trace
noise is 2.5 dB higher than when using Log Average.
annotation is displayed.
——Log Averaging (default) – Best for displaying Trace Averaging.
Also known as video averaging.
——Voltage (Magnitude) Averaging – Converts the amplitudes to a
magnitude unit before averaging (e.g., Volts, Amps,
microVolts, milliVolts, etc.)
— Average Count The Average Count setting is used with the Average
Trace State. In this Trace State, the Average Count setting
determines the number of acquisitions to average. The higher the
average count, the greater the amount of noise reduction (default:
10, minimum: 1, maximum: 10000).
— Sample Rate Sets the I/Q data sample rate value (default: 12.5 MHz,
maximum: 12.5 MHz, couplings: 1.25 * IF Bandwidth).
— Sample Period Sets the 1/Sample Rate value (default: 80 ns,
minimum: 80 ns, maximum: 80 ms, couplings: 1/Sample Rate).
