How to connect and synchronize 4824 8 channel and 5444b 4 channel picoscope

[waqas243]

Hello Everyone,
I am student doing Masters in Embedded Systems. I am using picoscope 5444b with four channels to take data
from coil sensor array and magnetic sensor array. now i want to upgrade my sensor and need 12 channel at same time so I buy another picoscope 4824 with 8 channels and now i want to connect two of them and synchronize them to collect the data. Any help will be appreciated.

Hi waqas243 ,

Unfortunately, you can only synchronize our 6000 series PiocScopes for an entire capture.

For our other PicoScopes, you can synchronize the start of the capture periods by sending the same signal to one input channel of each PicoScope to be able to get them to trigger within 1 sample period of each other. However, the PicoScopes would be highly likely to drift out of synchronization over the duration of the capture period (because their sample clocks are completely independent).

Hello,
thanks for the reply and for helping
Is it possible to connect 5444b and 4824 to increase the number of channels. If possible then how.
Is it possible to get data by using both scopes for 12 channels i can sacrifice few samples.

Hi Muhammad,

It is possible to capture data from more than 1 PicoScope at the same time, but not by using our PicoScope 6 software. You would have to either use our PicoLog software (which would limit the sample rate to 1kHz, or below) or by creating your own application using our Software Development Kit.

However, as mentioned previously, the data would not be in-sync (it would gradually become mis-aligned on the Time axis).

If you are using a sample rate that is 62.5kHz or less then you could use a PicoLog 1012 to capture 10.7ms of data on 12 channels simultaneously, and they would all be sychronized (although staggered one sample period apart).
