Re: Reading one sample at a time in Compatible streaming mod

OK. Lets assume that I use the Fast Streaming mode and aggregate data. Is there is a driver imposed limit on how fast my program can call 'ps2000_get_streaming_values'? Can I call it every mili second?

Re: Reading one sample at a time in Compatible streaming mod

Its just an experimental setup trying to sample an analog signal where the user program reads the voltage value at the desired time. The best option for this purpose would be to have an API function that just reads a sample value from an input channel when invoked without starting any sampling/strea...

Re: Reading one sample at a time in Compatible streaming mod

I have a framework for running programs that runs a code segment repeatedly at a desired frequency. The framework allows to have an initialization code segment (the code that runs only once in the beginning) and then the code segment that is executed repeatedly. The code looks as follows: /* Initial...

Reading one sample at a time in Compatible streaming mode

Hi! I am using a 2204 device and I want to read one sample at a time (every 10ms) in the Compatible streaming mode. So I use ps2000_run_streaming(handle, 10, 1, 0). Now inside a while loop, I read value using ps2000_get_values(handle, &value, NULL, NULL, NULL, &overflow, 1) here value and overflow a...

Re: Arbitrary waveform generator issue

Thanks Martyn for your reply. I'll write to support@picotech.com. But I dont think its the hardware limitation. Because when I use Picoscope 6 software's Signal Generator interface and then change some signal properties while the signal is being produced and viewed on a dedicated Oscilloscope, I don...

Arbitrary waveform generator issue

Hello! I am using a 2205 device and want to use the AWG to produce a wave. With a fixed waveform, it works fine as I call the ps2000_set_sig_gen_arbitrary function once with some values and the waveform is produced as expected. But if my program wants to change the data in the buffer (to change the ...

Re: AWG in LabVIEW PS2000.dll

Why 4094? Should not it be 4096?

Programming AWG

Hello! I have a 2205 device. I want to capture a signal from one of the channels, "modify" it and then "play it back" using the AWG feature. In the PicoScope 6 documentation, I read the following: ".... you can even capture a waveform using your oscilloscope, modify it (if needed) using the AWG edit...

Re: Not able to read values in 2204/2205

Got it. Realized after posting my message that the voltage range needs to be adjusted (default was PS200_20V). My signal was in the range of ±100 mV.

Thanks anyway for the reply.

Not able to read values in 2204/2205

I recently bought a 2204 and a 2205 devices. While using the program PS2000con.c given with drivers/sdk, I am not able to get any meaningful value. It does not matter weather I connect a signal to a channel or not. I always get almost same values. 7, 7, 7, 7, 7, 7, 7, 7, -284, -284, 7, 7, 7, 7, 7, 7...

Picoscope: new Linux driver for 2204 & 2205

Hello! I recently purchased 2204 and 2205 devices. I notice that the Linux driver available for these devices is very old (works with Fedora 8). However, in the Labs, there is a newer version available for 3000 A and B Series devices (that works with Ubuntu 10.10/11.04). Can this driver be used for ...
