3.3 REMOTE MODE PROGRAMMING
NOTE: The VISA query function (included in the latest versions of the VISA libraries) is not
supported by the MBT Power Supply. In newer XP and Vista computers a delay is
needed to insure the MBT Power Supply has time to return the response to the query.
The VISA query has no provisions to add a delay, nor can it issue a series of read
strobes between sending the request and receiving data from the device. Instead of
the VISA query, use one of the two methods described below. Method 2 is recom-
mended.
1. Use a VISA Write followed by VISA Read with a small delay between the functions.
The delay is determined by computer speed. A 2 millisecond delay between the Write
and Read functions will be sufficient to insure that there is enough time to receive a
response for all valid queries.
2. Follow the VISA Write with a series of VISA Read strobes while waiting for the data
available bit to be true, followed by the VISA Read function when data is available. This
method provides the highest throughput.
