Problem displaying 1PPS time signal from GPS Receiver

Post by Marlie »

Hello,
I have a Picoscope 2000 series scope and am trying to display a 1pps signal coming from a GPS receiver.
The scope is showing the signal in a random way. For example, it will correctly display the pulses every second for between 4 and 6 seconds and stop displaying them. Seconds later it displays a number of pulses again in the same way and once again stops.
Please let me know what might be causing this.
Thanks.

Hi Marlie,

Can you save and post a psdata file of what you are seeing.

Also, how are you able to confirm that the pulses aren't just not being received at the input channel, when they are no longer being displayed? (are you capturing them on another measurement device at the same time?). And what is the GPS receiver that you are using?

Regards,

Gerry
