Hi
I’m having some problems when I try to export the waveforms from PcLab2000. I use a Pcsgu250 Oscilloscope and intend to use these waveforms in QtOctave. When I use the export functions or the save dso data text file I get a text document that doesn’t do what I want. Basically, I have a simple circuit and have measured the voltage over the source and two points in the circuit. What I want to do is to create a diagram with the three sinewaves in octave. I’ve tried exporting them as waveforms and dso data with the source as ch1 and the two points on ch2. I’ve also tried exporting each sine with the other channels coupling set to gnd. Then I subtracted the gnd-value from the sine-value. This at least makes the waves go through zero, but they end up with incorrect phases.
I can’t upload any files unfortunately, but i’ll give two small examples from the dso data files.
First one:
TIME STEP:
125 = 10ms
VOLTAGE STEP:
CH1: 32 = 3V~
CH2: 32 = 1V~
GND 125 125
N CH1 CH2
69 177 204
70 176 205
71 176 205
72 175 207
73 175 207
74 174 207
75 174 207
76 173 208
77 173 208
78 173 208
79 171 209
CH1 ís the voltage source and CH2 is node A. These values are the respective maximums. Max voltage in the source were measured to 4.97V and in node A 2.63V.
Second one:
TIME STEP:
125 = 10ms
VOLTAGE STEP:
CH1: 32 = 1V~
CH2: 32 = 3V~
GND 125 127
N CH1 CH2
427 120 179
428 120 177
429 120 177
430 120 177
431 120 177
432 120 177
433 120 177
434 120 177
435 120 177
436 120 176
437 120 176
438 120 175
439 120 175
440 120 175
441 120 173
442 120 173
443 120 172
444 120 172
445 120 171
446 120 171
447 120 170
448 120 169
449 120 168
450 120 167
451 120 167
452 120 165
This time the voltage source is CH2 and CH1 had it’s coupling set to GND (if it matters somehow the probe was most likely still attached to node A). 179 is the maximum value on the source and the max was measured to the same as before.
Does anybody have any ideas what to do?
