Field strength measurement with spectrum analyzer
Utility
Gate Sweep Spectrum
To get appropriate gate sweep spectrum, you have to set the gate delay and gate length in a way that the measurement is active
during the interesting part of the signal. You can also modify the sweep time in order to match the horizontal axis to the length of the
signal and thus set the gate delay and gate length parameters more accurately.
The gate delay parameter means the time between the trigger event and the beginning of the actual measurement. The gate length
means the duration of the measurement, before it is interrupted and the next gate signal is expected to resume the measurement.
The measurement settings can be saved and recalled as a file by selecting File Type as Setup and load the file onto the instrument
using the
Save/Load icons on the side bar.

Setting Gate Sweep Spectrum
The above figure is the first screen you will see when entering the gate sweep measurement mode.
1 Tap Gate Delay on the setup table and input a value using the on-screen keyboard.
When the gate delay changes, the gate length line also changes accordingly with the same interval.
2 Tap Gate Length on the setup table and input a value using the on-screen keyboard.
The gate length cannot be moved on the left side of the gate delay.
