Using Gating to Characterize a Burst Signal

To Use Time Gating

First we’ll look at the spectrum of the signal and see that three components exist. Then we’ll look at the time display of the burst signal and analyze each burst separately to determine which spectral components exist in each burst.

1Select the baseband receiver mode and initialize the analyzer:

Press [Instrument Mode] [receiver] [RF section (0-10 MHz)]. Press [Preset].

2Load the source signal file BURST.DAT into data register D3:

Insert the Signals Disk in the analyzer’s disk drive.

Press [Save/Recall], [default disk], [internal disk] to select the internal disk drive. Press [Return] (bottom softkey), [catalog on] to display the files on the disk. Rotate the knob until the file BURST.DAT is highlighted.

Press [recall trace], [from file into D3], [enter].

3Connect the SOURCE output to the INPUT with a BNC cable.

4Turn on the source and select arbitrary signal D3:

Press [Source], [source on], [source type], [arb data reg], [D3], [Return], [arbitrary]. Press [Average], [average on].

The display should now appear as shown below.

The spectrum with averaging turned on. Note existence of three components.
