HPG 13150 400 V (A) Communication Interfaces 4-41
HPG™ 13150 400 V RF Power Generator
Prerelease version
• Command numbers 128 through 255 request information from the unit,
such as output on/off status and unit settings. The unit responds to these
commands by sending the data requested.
For AE bus, unless otherwise specified for individual commands, any value
greater than one byte must be sent and received least significant byte (LSB)
first. For example, if a command contained 7 data bytes made up of one 8-bit
value, one 16-bit value, and one 32-bit value, the 7 data bytes would be sent
in the following order:
0, 2, 1, 6, 5, 4, 3 (0 = 8-bit value, 2 and 1 = 16-bit value, 6 through 3 = 32-bit
value).
Most host port commands are the same for all of the available interfaces.
Differences are noted where they exist.
Table 4-13 describes the HPG
generator host port commands.
