Trig-Delay

The trigger delay is used to specify the time relationship between the trigger and displayed signal.

•Positive values delay the measurement trigger by a specific period. The delayed trigger point is the left edge of the screen.

•Negative values perform a pre-trigger function, displaying a section of the waveform before the trigger point. The trigger point is indicated by small pointers that appear at the top and bottom of the screen.

Operating Considerations

Negative Values. The maximum negative delay cannot exceed ten divisions of the current Time/Div setting. For example; if the Time/Div field is set to 1 ms, the maximum allowed negative delay is -10 ms. Larger negative numbers cause an Excessive negative Trig-Delay will be truncated. message.

Positive Values. For Time/Div settings of 50 ms/Div and smaller, the maximum delay is 400 ms.

For Time/Div settings of 100 ms/Div and larger, the maximum delay is 3200 ms.

Resolution. For delays of 400 ms and less, the resolution is 6.4 ms. For delays greater than 400 ms, the resolution is 51.2 ms. All entries are rounded to the nearest multiple of 6.4 ms or 51.2 ms (depending on the delay value).
