Description of Items in Figure 5-24

1Output from pulse generator 1.

2Output from pulse generator 2.

3Pulsed RF signal input to the spectrum analyzer.

4Gate output from time-gated capability. Notice that the gate output is directly below signal 2.

10.Set the resolution bandwidth to a value that is greater than 2 divided by the gate delay (110 ps) minus the signal delay (85 ps). The resolution bandwidth should be set to greater than 2 divided by 25 ps, or greater than 80 kHz. Press Isw_l, RES 3W , 100 m.
