st the trigger level control for a stable display.
11 The test passes if triggering is stable. Record the result in the Performance Test Record.
12 Set the signal frequency to 500 MHz and the output level for 1 division of vertical
deflection.
Again, you can use the markers to check the deflection, with one set to +100 mV and the other
to –100 mV.
13 Adjust the horizontal sweep speed to 1 ns/div.
14 Adjust the trigger level for a stable display.
15 The test passes if triggering is stable. Record the result in the Performance Test Record.
16 For the Agilent 54830B/31B set the signal frequency to 600 MHz. For the Agilent
54832B/D & 54833A/D set the signal frequency to 1 GHz. Set the output level for 1.5
division of vertical deflection.
17 Adjust the Horizontal sweep speed to 1 ns/div for the 54830B/D & 54831B/D or 500
ps/div for
the 54832B/D & 54833A/D.
18 Adjust the trigger level for a stable display.
19 The test passes if triggering is stable. Record the result in the Performance Test Record.
20 Connect the signal generator to the channel 2 input.
21 Repeat steps 4 through 16 for the remaining channels.
Procedure—External Trigger Test (2-channel models only)
This test is necessary only on the Agilent 54830B/D & 54833A/D.
1 Connect the equipment.
a With the N cable, connect the signal generator to the power splitter input.
b Using an N-to-BNC adapter and BNC cable, connect one splitter output to the channel 1
input.
c Press the channel 1 button to turn the channel on. Set the channel to 50Ω, DC coupling.
d Connect the second splitter output to the Ext Trig input.
2 Set the signal generator frequency to 100 MHz and the output level to 32 mV
rms
(90 mV

into the trigger).
3 Press Autoscale.
4 Use the Ext Trig Input Range knob to set the range to ±1 V. Set Input to 50Ω and coupling
to dc.
5 Press the Source key to select Ext.
6 Press the Sweep key to select Trig’d.
7 Adjust the trigger level for a stable display.
8 The test passes if triggering is stable. Record the result in the Performance Test Record.
9 Set the signal generator frequency to 500 MHz and output level to 64 mV
rms
(180 mV

into the trigger).
10 Adjust the trigger level for a stable display.
11 The test passes if triggering is stable. Record the result in the Performance Test Record.
