34970A Labview program

["Steven E. Williamson" <sew@npl.uiuc.edu>]

Peter,

The Labview program which (I think) is the latest version of
what we used to read out the Agilent 34970a using the serial
port is on my www.npl.uiuc.edu/~sew/ directory under the name
34970a-voltage-readout-serial.vi.  This is quite similar
to the GPIB version of the program except 1) the GPIB
initialization was converted to COM1 (I thought that there
would be additional parameters for this serial init. but apparently
the defaults were used -- and worked).  2) Jacob or Dannette
added an additional time constant: a wait after one cycle of
reading selected channels was completed (this is in addition
to the wait (dwell time) between individual channels).  I
suppose this added time constant was needed in order to
get a set of voltages rapidly (and therefore correlated in
time) without wearing out the multiplexor (and generating
way too much data).  Let me know if this to works.
