Timebase Frequency

Results

Window One (Time Record)

Shows an I/Q display of the frequency difference between the input signal and the internal 10 MHz signal.

Window Two (Magnitude)

Shows a polar representation of window one. This window shows how much the phase error changes during the sampling period.

Window Three (Freq Error)

Shows a stripchart of the timebase error in MHz vs. time. Each dot on the horizontal axis is one sampling period.

Window Four (numeric results)

Freq error: The error difference between the 10 MHz input signal and the internal 10 MHz signal.

Magnitude: The magnitude of the external 10 MHz signal. While this is an uncalibrated value, it gives the user an idea of the signal amplitude.

Adjusting: A 0 will appear if the timebase adjustment is not being performed. A 1 will appear if the adjustment is being performed.
