@Andreas
How do you make those graphs from a .csv ... Teach me please
Is it gnuplot ?
Can i get the "script/commands" ?
On the 3457 i used 100NPLC (Max)
On the K2015 i used 10NPLC (Max) , the K2015 has filtering enabled (i think default is 10 measurement moving average)
The temperatures are "bad" , as i had another linux program also accesing my USB-AVR temp logger (/dev/TTYACM0) , at first
t thought it was cool that 2 programs could acces the temp sensors. But then i discovered that they both send temp sensor commands , and the readings then got mixed up. I'ts actually funny that you can read/write from two tasks to one serialport .
I have stopped the 2'nd task , and attached another csv file.
My SVR on the Keithley , and SVR-T on the 3457A are lying in free air unencapsulated on the table.
And i'm an bit surprised that there can be 0.8C difference from the two boards that are maybe 15 cm apart.
Edit:
Ohh and remember both meters are 6.5 digits , even though the gpib returns more digits.
I haven't utilized the extra digit on the 3457A yet ....
Edit2: 11-jan - Uploaded a newer zipdile with more measurements in it
