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 95), setting a marker function before you set marker points may
change the RF output. RF Blanking includes ALC hold (described on page 90, 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 95).
2. From the
Marker Utilities menu (page 92), assign RF Blanking to Marker 1:
Press Marker Routing > Pulse/RF Blank > Marker 1.
