Constant delay block
When trigger model execution reaches a delay block, it stops normal measurement and trigger model
operation for the amount of time set by the delay. Background measurements continue to be made,
and if any previously executed block started infinite measurements, they also continue to be made.
This delay waits for the set amount of delay time to elapse before proceeding to the next block in the
trigger model.
If other delays have been set, this delay is in addition to the other delays.
When you select the Constant Delay block, the following option is available.
Setting
Description
Delay
The amount of time to delay in seconds
Dynamic delay block
When trigger model execution reaches a dynamic delay block, it stops normal measurement and
trigger model operation for the amount of time set by the delay. Background measurements continue
to be made.
Each measure function can have up to 5 unique user delay times (M1 to M5). Digitize user delays are
handled as measure user delays, so you can have a total of 5 measure and digitize user delays. Each
source function can also have up to 5 unique user delay times (S1 to S5). The delay time is set by the
user-delay command, which is only available over a remote interface. If you are using SCPI, the user
delay commands are
[:SENSe[1]]:<function>:DELay:USER<n>
(on page 6-59) and
:SOURce[1]:<function>:DELay:USER<n>
(on page 6-91). If you are using TSP, they are
(on page 8-218).
This delay can be different for every index in a configuration list. This makes it possible to have a
delay that changes as a configuration list progresses.
When you select the Dynamic Delay block, the following option is available.
Setting
Description
User Delay
The user delay to recall.
Notify block
When trigger model execution reaches a notify block, the instrument generates a trigger event and
immediately continues to the next block.
Other commands can reference the event that the notify block generates. This assigns a stimulus
somewhere else in the system. For example, you can use the notify event as the stimulus of a
hardware trigger line, such as a digital I/O line.
Setting up the notify block using the front panel:
When you set up the notify blocks using the front panel, you select the line or timer to notify. You also
set specifics regarding the line or timer. The stimulus and logic for input and output lines are set up
automatically. The notify event number is also set automatically and is displayed at the bottom of the
Notify definition screen.
