Re: Setting advanced trigger for PicoScope 4824

Hi Hitesh, info = (PS4000A_CONDITIONS_INFO)(PS4000A_CLEAR | PS4000A_ADD); As you said, it means that the driver will clear any previous trigger conditions that were set and add the new trigger conditions. In the sdk guide, "info = PS4000A_CLEAR" also means clear previous conditons and add the curren...

Re: Problem of stop the Picoscope in Labview

Hi Hitesh, Previously, I have learned about the issue from njustzr. it works well on USB2.0 port while it only have the issue on USB3.0 port.

Re: pulse width trigger

Hi Chris,

How to set the triggerHysteresis in TRIGGER_CHANNEL_PROPERTIES structure? For 1.5% what should this value be? what is the mean of 256*10 in the API demo?


Many Thanks.

Re: Using Picoscope with Belkin USB hub

Hi Hitesh, As for what you said previously, i feel a little confused. The buffer memory is used as a cache on the device but you would need to ensure that enough data can be transferred to the PC to avoid the memory from becoming full and thereby losing data. In the quote, do you mean that effect is...

Re: Using Picoscope with Belkin USB hub

Hi Hitesh, Thanks for your response! I taked a look at IOGEAR Wireless 4-Port USB Sharing Station GUWIP204 and noticed that it support 802.11b/g/n compliant- up to 150Mbps. However, as we all know, PicoScope could manage the USB2.0 speed greater than 30MBytes(240Mbps). so i think GUWIP204 maybe lowe...

Re: Using Picoscope with Belkin USB hub

Hi Hitesh,

Since you have tested that PicoScope could collect data romotely with Belkin Network USB Hub. Do you know what is the maximun comunication distance ? And what is the data rate of the network USB Hub? Does the network USB Hub limit the communicating rate of PicoScope?

Many Thanks

Hi Hitesh, In the programmer guide of ps5000Apg.en, when refer to ps5000aGetValues, it says, it is used to get the stored data from the "drive" after data collection has stopped. when refer to ps5000aGetValuesAsync, it says, it used to get the stored data from the "scope" after data collection has s...

So i can't wait to share with you. Maybe you are also exploring the same deivce. I have tried PicoScope 6404D , 5244B and 2207 and...

Re: PicoScope6 with tablet PC

Hi All, I have tried to run PicoScope 6 on a Lenovo ThinkPad 8 (20BN000WCD) Tablet with win 8.1 OS and it does work. See the attached picture. The only downside is that the tablet has a power shortage for PicoScope. so in the attachment, we use a double USB cable with the power port on the other PC ...

Re: The USB bottleneck myth debunked

Hi alan, As described above the scope uses the hardware acceleration to quickly form and transfer the image to be displayed to the PC. Can we use the hardware accerleration with deep memory PicoScope when writing our own application? if so, which function can we use in SDK like 5244? is it ps5000aGe...

Have you added pulse count feature into the latest version of PicoScope 6? where? Recently, we have the same need too.
