7 Analog Modules Time Interval Analyzer

230 System Reference, January 2001

• Auto Trigger mode

This mode uses the edge of the input signal to channel

1 or 2 as the trigger, as follows:

– ARM on Start:

The TIA starts the interval measurements from the

next pulse after the specified edge of the channel 1

input signal is detected as a trigger.

For the dual channel measurement, the TIA

measures the interval from the specified edge on

channel 1 to the specified edge on channel 2.

However, if the TIA detects the edge on channel 2

before the edge on channel 1, the measurement data

is a negative value.

This function is available for PW/PER/FREQ

measurements on channel 1 and PD measurements.

– ARM on Stop:

The TIA starts the interval measurements from the

next pulse after the specified edge of the channel 2

input signal is detected as a trigger.

For the dual channel measurement, the TIA

measures the interval from the specified edge on

channel 1 to the specified edge on channel 2.

However, if the TIA detects the edge on channel 2

before the edge detection on channel 1, the

measurement data is a negative value.

This function is available for PD measurements.

– ARM Start First:

The TIA starts the interval measurements from the

next pulse after the specified edge of the channel 1

input signal is detected as a trigger. This mode

requires a minimum 1 ns setup time.

For the dual channel measurement, the TIA

measures the interval from the specified edge on

channel 1 to the specified edge on channel 2. Even if

there are some edges on channel 2 before the edge
