Chapter 3 109
Basic Digital Operation
Using Waveform Markers
Using the RF Blanking Marker Function
While you can set a marker function (described as Marker Routing on the softkey label) either before or
after setting the marker points (page 104), setting a marker function before you set marker points
may change the RF output. RF Blanking includes ALC hold (described on page 98, note Caution
regarding unleveled power). The signal generator blanks the RF output when the marker signal goes
low.
1. Using the factory–supplied segment SINE_TEST_WFM, set Marker 1 across points 1−180 (page 104).
2. From the
Marker Utilities menu (page 101), assign RF Blanking to Marker 1:
Press
Marker Routing > Pulse/RF Blank > Marker 1.
RF Output
