Thank-you for your post with regard to triggering on your filtered acquisition. As Martin described triggering occurs on raw data.
Some of our products have a bandwidth limit. Please could you inform me what device you are currently using.
Bandwidth Limit: a fixed-frequency single-pole analog filter. This can be useful for rejecting noise and harmonics that would otherwise cause aliasing.
Another option would be to acquire the data over a longer period of time. PicoScope 6 has two modes of operation. Block and streaming mode. You potentially acquire a larger amount of data depending on your requirements. Please could you inform me how long you are wanting to acquire your data for. You could in theory capture a large amount of data and then apply the filter to all your data.
In streaming mode, PicoScope 6 tells the scope to capture data continuously and, at the same time, to transfer each sample to the PC with minimum delay.
At longer timebases (more than 1 sec across the screen) data is drawn on the screen at the same time as it is collected. In this mode data is "streamed" continously across the USB link.
We have made significant improvements to this USB streaming which for most devices currently on sale has increased the streaming sampling rate from 1MS/s to 10MS/s.
As well as the improved sampling rate, streaming mode uses the PC memory for waveform storage so is not limited by the buffer memory of the oscilloscope hardware. A massive 100 million samples can be collected using PicoScope in streaming mode.
The following models can now stream data in PicoScope at 10MS/s for a single channel and 5MS/s for two channels and 2.5MS/s for 3 or 4 channels: PS3204A/B, PS3205A/B, PS3206A/B, PS2205MS0, PS2206, PS2207, PS2208, PS5203, PS5204,PS6402, PS6403, PS6404, PS6407, PS4224, PS4423, PS4227, PS4224, PS4223, PS4262, PS4224IEPE.
The following models can now stream at 6.6MS/s for a single channel, 3.3M for two channels and 1.65MS/s for three or four: PS2202, PS2203, PS2204, PS2205, PS3223, PS3224, PS3423, PS3424, PS3425.
The PS2104, PS2105 and original PicoScope 3200 series (PS3204, PS3205, PS3206) are not covered by this upgrade.
This way you could capture all your data and use the Power of PicoScope 6 to zoom into the data, apply filtering and conduct further analysis.
I look forward to your response.
