Re: ps3000aGetTimebaseStateles() Documentation

ps3000aGetTimebase-2, and ps3000aGetTimebase2-2, is not in that manual. What is the meaning of the -2 suffix? Many, but not all, functions in the dll have this suffix. I have no idea what is different about them, and whether or not to use them. I do not see this -2 suffix documented anywhere.

Fastest Sample Rate

Attached is a screen shot of LabVIEW code that is my attempt to read from whatever PicoScope 3000 series happens to be connected to the computer the shortest sample interval it is capable of. The theory: 1) A time base if 0 should get the fasted sample rate according to page 15, section 3.6 of: http...

ps3000aSetSimpleTrigger() outputs a status of PICO_AUTO_TRIGGER_TIME_TOO_LONG

From the function ps3000aSetSimpleTrigger() I get a status code of 0x4000. According to the file PicoStatus.h this is "PICO_AUTO_TRIGGER_TIME_TOO_LONG". This is not one of the possible status outputs for this function as given in: https://www.picotech.com/download/manuals/picoscope-3000-series-a-api...

ps3000aMaximumValue() Returns Wrong Value

According to the label on the underside of my PicoScope 3205D this has an 8 bit ADC. When the function ps3000aMaximumValue() is called on the 3205D I get a value of 32512, which is consistent with the signed output of a 16 bit ADC. I expected to use ps3000aMaximumValue() to make my application compa...

Re: ps6000aRunBlock-2() Relay Clatter

I have seen many functions with the -2 suffix, and these are the ones I have been using. What does the -2 suffix indicate? Is it true that all such functions having the -2 suffix should not be used? Or is this true only of ps6000aRunBlock-2?

Re: What are SetSimpleTrigger's delay units?

The answer is found in the function ps6000aSetTriggerDelay()'s description. The time unit is the time between samples. The number of samples to delay by is entered here.

ps6000aRunBlock-2() Relay Clatter

The function ps6000aRunBlock-2() is working within the application I wrote in LabVIEW which repeatedly reads data from a PicoScope 6424E. Trouble is I hear relay clatter every time this function is called. I start up PicoScope6000aExampleBlock.vi , there is initial clatter, but it is soon silent, an...

In the document at: https://www.picotech.com/download/manuals/picoscope-6000-series-programmers-guide.pdf The ps6000aSetSimpleTrigger() function in section 3.55 there is the delay argument. The unit for this unsigned 64 bit parameter is not given. What is it? Is it the same as for the autoTriggerMic...

Reading Max Sample Rate from a PicoScope

I have a PicoScope 3205D. The application I am working on is written in LabVIEW. I desire to read back from a PicoScope device these items: 1) How many channels have been enabled, and which of are enabled. 2) The maximum sample rate any of the 3000 series that happen to be connected are capable of. ...

Re: ps3000aGetTimebase() outputs Invalid Handle error

This problem is solved. In the LabVIEW call to ps3000aGetTimebase() the handle was set to pass by pointer. This must be set to pass by value. Once set to pass by value there was no error produced.

ps3000aGetTimebase() outputs Invalid Handle error

ps3000aGetTimebase() outputs a PICO_STATUS value of 0x0C, which is an Invalid Handle error, in spite of the handle having been successfully used just prior to this call. The VI in which the call to ps3000aGetTimebase() is called is attached. I have also attached the VIs that use this VI. The VI that...
