AWG Sweep Sync - 5204

Postby njsmersh » Wed Oct 13, 2010 11:21 pm

Hi,
How could the AWG get synced externally in a sweep mode? Or can it generate a pulse to sync the scope itself when a sweep starts?

Thanks

Hi There,

Thankyou for your inquiry with the AWG functionality. In order to assist you further please could you provide more detail of what you want to achieve.

Kindest regards,

Well,
Let's say I want to measure a filter V/F characteristics. Thus, I'm applying a sweep from the AWG to the input of the circuit, and I'm measuring the output with the CH1. To see a "nice" picture, the scope needs to get synced from the sweep "start" point, so that the full output fits the scope screen without jittering.
To achieve that, either scope needs to get synced from the sweep start point or the sweep generator itself - from the scope's sawtooth (old school).

Thanks for your reply,
NJ

Dear NJ,

One option is to use the pulse width trigger in the advanced triggers of PicoScope 6 this should trigger the scope on a particular frequency in the sweep (such as trigger when pulse is less than x). This should then trigger the capture when the sweep starts at the lowest frequency. Worth a try. There might be other trigger modes you could use or alternatively a mask dropout trigger.

Otherwise you will have to write your own code to setup the scope and AWG and then use software triggers to first trigger the AWG and then the scope. A lot more work but possible.

Advanced trigger types enable you to capture a stable waveform even with complex signals. Oscilloscopes that are capable of advanced triggering are ideal for troubleshooting glitches, timing violations, overvoltages and dropouts in analogue and digital circuits.

In this guide to advanced triggering we will review basic edge-triggering and its limitations, and then we will explore the possibilities that advanced triggering offers. Finally we will explain in detail how to set up advanced triggers in PicoScope 6.
