index error in extractdata.c

Travis W. Johnson — Tue, 28 Sep 2004 15:09:48 -0000

extractdata.c's inner loop of display data the index is
off for multiple curves such as IV curves.

The HP4145 writes out header data to mark the start of
a curve. The data with the start header needs to be
dropped from the output. Changing the printf line from

printf("%1.4e\t",
series[k][i * conf.svcbv.var1.steps + j +
1].data);

printf("%1.4e\t",
series[k][i * conf.svcbv.var1.steps + j +
1 + i].data);

seems to work since for n number of curves n header
(flag=1) data points are dropped.

var1 only sweep output error

Travis W. Johnson — Mon, 23 Aug 2004 23:55:22 -0000

If one runs extractdata on a hp4145 file that has only var1
sweep extractdata dumps extra data or no data at all.

4 byte negative number error in float

Travis W. Johnson — Mon, 23 Aug 2004 23:45:48 -0000

4 byte negative number is incorrect (too much is masked
off)

The 2's complement conversion should use 0xFFFFFF
similar to
the 3 byte version in get_struct.c.

See the attached diff.

doesn't support nonlinear sweeps

Isaac Lauer — Fri, 14 Jun 2002 21:41:16 -0000

If var1 isn't swept linearly, the program complains
that it only supports linear sweeps.
