c. ≥ 4 GHz models: Check B trigger system for stable triggering at limits:
Do the following subparts in the order listed.
■
From the button bar touch Trig, select the A Event tab, and set the
Source to Line.
■
Select the A->B Seq tab, and touch the A then B Trig After Time
button.
■
Select the B Event tab, and touch the Set To 50% button.
■
CHECK that a stable trigger is obtained for the test waveform for
both the positive and negative slopes of the waveform. Use the
Trigger Level knob to stabilize the A trigger. Touch Level and use
the keypad or the multipurpose knob/Fine button to stabilize the B
trigger. Touch one of the Slope buttons to switch between trigger
slopes. (See Figure 34: Measurement of trigger sensitivity - 50 MHz
results shown on page 260.)
■
Enter pass or fail in the test record.
■
Leave the Delayed trigger system triggered on the positive slope of
the waveform before continuing to the next step. Also, return to the
A trigger: select the A->B Seq tab and touch the A->B Sequence A
Only button. Then select the A Event tab.
■
Select the A Event tab, and set the Source to CH1.
■
Press the X (Close button).
3. Confirm the AUX Trigger input (at 50 MHz):
a. Display the test signal:
■
Remove the 10X attenuator and reconnect the cable to Ch 1.
■
Set the signal amplitude as follows: 2.5 divisions
■
Now fine adjust the generator output until the Ch 1 Amplitude
readout indicates the amplitude is as follows (readout may fluctuate):
250 mV
b. Check the AUX trigger source for stable triggering at limits: Do the
following in the order listed.
■
Use the definition for stable trigger from step 2.b.
■
Press the Trigger Source button to toggle it to Aux (Ext).
■
Press Push-Set 50%.
■
CHECK that a stable trigger is obtained for the test waveform on
both the positive and negative slopes. Press the Trigger Slope button
to switch between trigger slopes. Use the Trigger Level knob to
stabilize the trigger if required.
■
Enter pass or fail in the test record.
