JMeter Terminology - Synchronizing Timer

I was tasked to perform a performance test for a web application using JMeter. Personally, I have some experience with LoadRunner but not JMeter. For one of the scenario, I need to simulate something like a Rendezvous Point in LoadRunner, therefore I was googling for something similar in JMeter and here it goes:- Synchronizing Timer

Rendezvous Point (LR) = Synchronizing Timer (JMeter)

Synchronizing Timer

The purpose of the Sync Timer is to block threads until X number of threads have been blocked, and then they are all released at once. A SyncTimer can thus create large instant loads at various points of the test plan.

Control Panel:

Synchronizing Timer

Parameters:

Attribute (1): Name
Description: Descriptive Name for the timer that is shown in the tree
Required: No

Attribute (2): Number of Simulated Users to Group by
Description: Number of threads to release at once. Setting it to 0 is equivalent to setting it to Number of threads in Thread Group.
Required: Yes
