Table 4. Command comparisons
34980A 3499A/B/C
Close channel 10 on the module in slot 3
ROUTe:CLOS (@3010) [ROUTe:]CLOS (@310)
Scan channels 0 through 40 on the module in slot 1
ROUTe:SCAN (@1001:1040) [ROUTe:]SCAN (@100:140)
and channel(s) rather than only
three digits as the 3499A/B/C
uses. Also, for the 3499A/B/C the
[ROUTe] in the command
structure is optional, where with
the 34980A it is required.
The 34980A offers new
measurement and module
capabilities such as counter/timer
and digital I/O with pattern
generator/detector that use
commands unique to their
functionality. Appendix A includes
a list of the 34980A and 3499A/B/C
commands as well as direct
comparisons of the commands.
SCPI Commands
The 34980A can be programmed
using SCPI commands or the IEEE
standard commands.
Configuration, measurements and
system control of the mainframe
and modules are easily achieved
using these instrument commands.
One difference between
instrument commands for the
3499A/B/C and the 34980A relates
to addressing specific channels in
the system. Table 4 shows an
example difference in 3499A/B/C
switch control commands
compared to 34980A commands.
Notice the 34980A uses four digits
to address the module slot number
IVI-C, IVI COM and LabVIEW
instrument drivers
34980A IVI-C, IVI COM and
LabVIEW instrument drivers are
available for simplified
programming. If you currently
program using Plug&Play drivers,
the IVI-C driver is similar and can
be used to program in the same
way. The IVI COM driver conforms
to the most modern IVI COM
instrument driver standard and
can be used in any programming
environment. LabVIEW
programmers are able to use the
34980A LabVIEW instrument
driver for their graphical
programming environment.
