Re: Buffer for the AWG

Hi Ian, Yes this is usual. It is the natural roll-off of the circuitry, and is why you see frequency specifications for analogue Channel inputs quoted as 0-xHz (-3dB) (sometimes they are quoted without the '-3dB' qualification, in which case it is implied). Most simple analogue circuitry (creating a...

Re: Implicit SetBandwidthFilter in ps5244d (ps5000a) API?

Hi gamaches,

Could you send in your code for a run, and a screenshot of the plotted data, so that we can have a look at exactly how you have set up the capture (if you would prefer you could send it in to our helpdesk at support@picotech.com).

Regards,

Gerry

Re: Macro Recorder Edit

Hi Red, Just so that you know, you can make slight changes to the times in the Macro editor, but if you want to make significant time changes then you need to save and edit the psmacro file. The psmacro file is an xml file, and the time is saved as absolute time hrs:mins:secs.thousandths, so you hav...

Re: PS3000A_ID_Streaming_Example application fft

Hi SG95, If an FFT was calculated using individual, or small groups of samples to plot small parts of the spectrum, gradually building up the complete spectrum over time, then it would be convenient to calculate and plot streamed data as it is being received. But when you perform an FFT you are tran...

Re: Macro Recorder Edit

Hi red03,

I don't see a problem with editing values to beyond 3m20s in the macro recorder (and saving and reloading them to use again).

Could you post your psmacro file and tell us what PicoScope you are using.

Regards,

Gerry

Re: Parallel recording of low and high frequency data

Hi Nepomukkk, If you are in a Spectrum view then the bandwidth you set is for all channels, so you can't perform live Spectrum captures on 2 channels using different Bandwidths. However, what you can do is use 2 different types of Spectrum views on data once it has been captured, as follows: 1/ Turn...

Re: ALARM-Capture Buffers Full - excess files

Hi paul, If you want 128 buffers of captured data written to a file repeatedly, which you can stop by hitting the stop button, then you can do that by adding a 'Restart capture' action to the end of your action list. I have created and attached a psdata file using your data file/settings that does a...

Re: ALARM-Capture Buffers Full - excess files

Hi pmohan, Looking at your alarm settings in your psdata file it appears that you have set alarms to go off for 2 events, i.e. on every capture and when the buffers are full, and then you are saving all buffers for both alarm conditions. If you only want the file to contain all 128 waveforms then yo...

Re: ALARM-Capture Buffers Full - excess files

Hi pmohan, Could you draw and post a rough diagram of approximately how you would like the capture to look once saved (using 3 waveforms instead of all 128) including labelling both channels (i.e. channel B as the transmit strobe pulse, if that is the case), and describe what you are attempting to a...

Re: Open source drivers for 2000 series

Hi PrzemoF, You're unlikely to find any open source drivers for our data acquisition devices, as we don't divulge how to communicate with them over USB, and we don't release any essential information about the Firmware (and changes to it that are inevitably made). This is deliberate as the informati...

Re: ALARM-Capture Buffers Full - excess files

Hi pmohan, I'm not quite sure what you are asking. In this scenario, a buffer refers to the waveform buffer split into multiple buffers, where each split buffer holds 1 waveform. So you have split the buffer into 128 buffers, each holding one waveform. when the Alarms function then writes out the ca...

Hi Brian, First of all, for anyone else reading this, the FAQ is being referred to is for PicoLog 5, not PicoLog 6. What the comment is referring to is the PicoLog 1000 sample rate of 1ms and the PicoLog 5 sample mode of real-time continuous . Real-time continuous mode is just transferring each sing...

Re: Measure 100% Rise Time

Hi Zalgo,

Can I ask why you need a 0 to 100% Rise Time measurement, as opposed to, say, a 1% to 99% Rise Time measurement (especially as a 0% to 100% rise time for an over-damped 2nd order system is infinite)?

Regards,

Re: Measure 100% Rise Time

Hi Zalgo, Not automatically using our measurement tools, which provide you with the 2 standard values of Rise Time measurement. There isn't a 0/100% Rise Time standard because it can take a disproportionately long time to converge on the 100% value of the input waveform (in some cases you may not ac...

Re: Measuring signal delay over a long time

Hi Benno, I don't know what the waveforms look like at a longer Timebase setting, but if they are periodic squarewaves, you can increase the Timebase length to capture one complete cycle, and then use Deep Measure to give you extremely accurate timings for the start of both waveforms. The timings fo...
