Chapter 5 To Trigger the Oscilloscope RIGOL

DS1000Z-E User Guide 5-15

Pattern Trigger

Identify a trigger condition by looking for a specified pattern. This pattern is a logical

"AND" combination of channels. Each channel can have a value of high (H), low (L)

or don't care (X). A rising or falling edge (you can only specify a single edge) can be

specified for one channel included in the pattern. When an edge is specified, the

oscilloscope will trigger at the edge specified if the pattern set for the other channels

are true (namely the actual pattern of the channel is the same with the preset

pattern). If no edge is specified, the oscilloscope will trigger on the last edge that

makes the pattern true. If all the channels in the pattern are set to "Don’t Care", the

oscilloscope will not trigger.

Trigger Type:

Press Type, rotate to select "Pattern" and press down . At this point, the

trigger setting information is displayed at the upper right corner of the screen.

For example, . The trigger type is pattern trigger; the current

trigger source is CH1; the trigger level is 0.00 V.

Source Selection:

Press Source to open the signal source list and select CH1 or CH2. For the details,

please refer to the introduction in "Trigger Source". The current trigger source is

displayed at the upper right corner of the screen.

Pattern Setting:

Press Code to set the pattern of the current signal source. At this point, the

corresponding pattern is displayed at the bottom of the screen. The patterns of

channels CH1 and CH2 are presented from left to right as shown in the figure below.

 : set the pattern of the channel selected to "H", namely the voltage level is

higher than the trigger level of the channel.

 : set the pattern of the channel selected to "L", namely the voltage level is

lower than the trigger level of the channel.

 : set the pattern of the channel selected to "Don’t Care", namely this channel

is not used as a part of the pattern. When all channels in the pattern are set to

"Don’t Care", the oscilloscope will not trigger.
