Dear all,
I used the sigal generator in Picoscope6, all correct.
When I try to find icon Signal generator in Picoscope7, I haven't got is yet.
Many thank for your help, how to configurate Signal generator in Picoscope7 please.
Kind regards
Xavier

Many thanks for your answer.
I have converted a data file into *.m (under picoscope6, in fact, I don't find "Save as" with picoscope7?).
Therefore, Octave read only *.mat (not *.m)
I will discuss with my colleague who uses Matlab if there is a solution.
Kind Regards
Xavier

Many thanks and I'll try this solution.
Cheers
Xavier

Many thanks for Martyn to send a clear and complete response!
Warm regards

Hello,
I'd like to re-compute FFT analysis on the recorded waveform (*.psdata).
Is there some body who knows a solution with Picoscope 6?
Many thanks in advance
Warm regards

Dear technical support team, My question may be related to my personal understanding about the mode "CollectStreamingTriggered(UNIT_MODEL * unit)" with PS4262. I set trigger voltage = 100mV, preTrigger = 0 or 1000; I have used the C++ examples in github and made some minor modification on recorded d...

Dear technical support team, My ps4824a is now operational with BlockDataHandler (with or without trigger). May I continue this discussion for the function ps4000aRunStreaming(unit->handle, &sampleInterval, timeUnits, preTrigger, postTrigger, autostop, downsampleRatio, ratioMode, bufferLength) that ...

Dear Martyn, Many thanks for your continuing help. When I check all my program libraries this afternoon, I realized that ps4000a.dll I used is dated in April 2019. I have then updated the last one in SDK dated September 2021 (I have regenerated ps4000a.lib for my C++Builder). Very good surprise, my ...

I have tested with a DC signal generator, Scale of ChannelA: 10V with DC coupled. Here are the results: Voltage generated Measured in Int 0V -32767 1.6V -32767 2.5V -29817 5.0V -21604 7.5V -13523 9.9V -5423 -1V 32767 -5V 21746 There is a dead band from 0 to 1.6V with wrong values. For the rest int v...

Here are the test results: Case 1: ChannelA: 50V, ChannelB:0.1V, are DCCoupled, nothing connected. Timebase, SampleInterval: 199 , 2.5E-6 Returned timeIndisposed = 252 First N-points readings, Channel readings are in ADC Counts and mV Channel A Channel B -32767 -49954 32767 99 -32767 -49954 32767 99...

I have tried to set (PS4000A_RANGE)unit->channelSettings[PS4000A_CHANNEL_A + i].range: 5, 10 and 50V. In all these cases, buffer values are always -32767, +32767, i.e. .range doesn't have any effect on the channels. Furthermore, when DCCoupled is enabled, results are even worse: almost all saturatio...

I have taken the following function (sorry, I don't totally understand the content): void SetDefaults(UNIT * unit) { PICO_STATUS status; PICO_STATUS powerStatus; int32_t i; unit->resolution = Form1->ComboBox2->ItemIndex; // 0 to 4 (I have tested from 8bits to 16 bits) if (unit->hasETS) { status = ps...

Just a result of some additional tests with signal generator: ChanelA is connected to a signal generator: 0 to 2.5V, 10kHz square waveform. ChanelA is set to no DC coupling (otherwise, all saturation). ChanelB is short-circuited with 50 Ohm resistor The recorded time step is correct according to fir...

Great! Thanks of your help, it progresses, although I haven't got yet successful result. Here are modified codes: void BlockDataHandlerXY(UNIT * unit, int8_t * text, int32_t offset) { int32_t timeIndisposed; int32_t maxSamples; int32_t i, j; float timeInterval; int32_t sampleCount = BUFFER_SIZE; int...

In fact, there is no error returned, only status = 286. I have tried with a computer with true USB3.0, always 286 returned.
I have tried with a sampleCount of 1000 and a timebase of 2000: the same as before, timeIndisposed didn't change.
Many thanks
Xavier
