Data Transfer Modes

The VT1433B can be programmed to use either of two data transfer modes: overlap block mode and continuous mode. Block mode will be discussed first.

Block Mode (Agilent/HP E1431A)

In block mode, the input hardware acquires one block after getting an arm and trigger. It does not allow the system to trigger until it is ready to process the trigger and it acquires pre-trigger data if necessary. The hardware does not accept a new arm and trigger until the acquired block is sent to the host. There is no provision for overlap or queuing up more than one block when in block mode. There is also no way for a FIFO overflow to occur.

The VT1433B’s overlap block mode can be configured to act exactly like traditional block mode. It also has additional capabilities as described below.

Continuous Mode

In this mode, the input hardware waits for an arm and trigger and then starts acquiring data continuously. If the host is slow, several blocks can be queued up in the input hardware. If the host gets far enough behind, a FIFO overflow occurs and the input stops acquiring data.

The VT1433B’s overlap block mode can be configured to act similarly to continuous mode, but not identically. The VT1433B can also use the traditional continuous mode.

Overlap Block Mode

Overlap block mode combines features of both block mode and continuous mode. The main difference between overlap block mode and traditional block mode is that overlap block mode allows additional arms and triggers to occur before an already-acquired block is sent to the host. A trigger can occur before the end of the previous block, so overlapping blocks are possible (hence the name “overlap block mode”). As in continuous mode, there is an overlap parameter which controls how much overlap is allowed between consecutive blocks.
