1,000,000). The “w” command should not be used on a periodic basis to continually update the
waveform (because of the limited number of write cycles, and to limit bandwidth usage).
11. When custom waveforms are run (output type in the “s” command is set to “Custom”) the
current and voltage settings from the custom waveform are used, the current and voltage
settings in the “s” command are not used.
12. The waveform can be named by adding a ‘:’ (colon) after the waveform index and then the
name of the waveform. The waveform name can have up to 8 characters and can contain any
alphanumeric character except ‘@’ and ‘,’. For example, this command will name waveform 1
on unit 01 as “abc123”; @01.1w1#1,1:abc123,54321.
13. Waveform names will be included in the reply to a read request onlyif delimiter text has been
enabled using the “i” command. Waveform names can be written with a set command
regardless of whether or not text delimeters have been enabled.
14. To provide the most accurate duplication of the waveform at the output all polarity changes
should occur at zero current output. The reversing bridge switches at the start of any segmen
where a polarity change occurs, therefore the reversing bridge will never switch in the middle of
segment execution. Any time a polarity change occurs the power supply output will go to zero
prior to the start of the segment having the polarity change and the segment will begin to run
after the bridge polarity changes. Therefore the most acurate duplication of a waveform having
polarity changes occurs when the segment prior to a polarity change has a zero current setting.
