Press the [ARM] softkey (F9) again.

Event Triggering

The AGILENT 35670A has the ability to trigger the acquisition of a time waveform based on the slope and level of the measured signal. To set up triggering properly, the polarity of the measured pulse must be known in advance: will the event start with a negative slope or positive slope? Will the event be mostly positive or mostly negative? Use trial measurements to determine polarity if unknown.

Proper triggering is also affected by the input range. Fortunately the AGILENT 35670A has the ability to set the trigger point to be a percentage of the input range, so even with CH1 AUTO UP ONLY, successful triggering should be possible automatically.

To specify trigger parameters for a “positive” event on channel 1 where the trigger point should have a positive slope, follow these steps:

Press the [Trigger] hardkey.

Press the [CHANNEL 1 2 3 4] softkey (F3) until 1 is highlighted.

Press the [TRIGGER SETUP] softkey (F6)

Press the [CHANNEL LEVEL] softkey (F1)

Enter 5 then press the [PERCENT (%)] softkey (F4)

Press the [SLOPE POS NEG] softkey (F5) until POS is highlighted.

Use pre-triggering to acquire some data before the trigger point. To set up a 0.01s pre-trigger condition, follow these steps:

Press the [Trigger] hardkey.

Press the [TRIGGER SETUP] softkey (F6)

Press the [ALL CHANNELS] softkey (F8)

Press the [CHANNEL * DELAY] softkey (F9)

Enter -.01then press the [S] softkey (F1)

To start the data acquisition,

Press the yellow [Start] hardkey.

The analyzer should show in highlighted text above the trace:
