SWEEP OUT
This procedure will verify that the SWEEP OUT output is functioning properly. It
will require the use of an oscilloscope.
1. Return the instrument to a known state by pressing Preset.
2. Connect the source rear panel SWEEP OUT connector to channel 1 of an
oscilloscope.
3. Setup the oscilloscope with the following settings:
— Channel 1 volts per division = 2 V
— Horizontal Scale per division = 50 ms
4. Turn the step sweep on by pressing Sweep, Sweep, Freq On.
5. The signal on the oscilloscope display should now be a 0 to 10 V ramp
with a duration of approximately 225 ms, as shown in Figure 10-9.

6. If the SWEEP OUT waveform is not being generated properly, replace the
A3 RF assembly.
