Command Timing

The output (response) data of the 8033 is sent in blocks of up to 80 bytes in length. It is sent using

high speed DMA within the 8033, but may be of indefinite length. Although some commands have a

definite length response, such as the "MESsage?" query, the response length is indefinite because

the 8033 will respond to multiple queries in a single response output. The user may enter as many

queries as desired in a single input message, and the 8033 will respond to all of them in the same

output message, if possible.

All query responses are evaluated at the time the query is parsed, and not at the time the response

message is sent. In most cases this does not create a problem since the time between parsing a

query and sending its response is small, unless the GPIB controller takes a long time to request the

response.

Output Off Register

The Output Off Enable Register allows the user to determine which conditions and events cause the

laser OUTPUT to be turned off. This register is configured in a manner which is similar to the status

reporting register. However, it's output is not reported in the Status Byte Register. Rather, it goes to

the hardware which controls the output switching. The events and conditions which may be set to

cause the laser output to be turned off are shown in Figure 3.4.

The default (factory) setting for this register is 0. This setting is not affected by the *PSC (Power−On

Status Clear) command.
