Hi melvyn, Unfortunately, it appears that we have a minor issue with multiple masks. So a better way to do this would be to use the alternative method that you suggested to collect the data (I can't see any immediate issue with the your method) then export the data to CSV, and either use a Module or...

Hi Peter, First of all, the answer on a postcard is - if you are trying to do what I think you are, then it can be done with a better NTC thermistor alongside your 10K NTC thermistor, and the TC-08. To explain why, you need to know about measurement goals, terminology, limits of measurement system c...

Hi Melvyn, What sample rate are you using? If you are not sampling too fast, you could use PicoScope 6 software to stream the data to the PC, and then automatically save a file when the waveform has been captured (using an Alarm), to provide a logging function, and you could then set a Mask for the ...

Hi nurber, If you measure a voltage with a DMM set to AC, the single value displayed is the RMS voltage. The equivalent DC voltage level that would provide the same amount of power when driving a resistive load over many cycles of the PWM waveform is referred to as TRUE RMS (not all DMM's perform th...

Hi natandmark, That is exactly what we do. There is an explanation on how we calculate IMD on page 185 of our User Guide here: https://www.picotech.com/download/manuals/picoscope6-oscilloscope-software-users-guide.pdf. For the measurement we look for the 2 highest peaks as F1 and F2 (you can specify...

Hi hadi_m, First of all, just so that you are aware, to perform 100base-TX analysis with a PicScope you should have a PicoScope that has a fast enough sample rate, i.e. ≥375MS/s. Note - If you're not interested in how we arrive at 375MS/s then skip to the next paragraph. So, for 100Base-TX using MLT...

Hi nurber, The answer to your question is that the 'Zero offset' function, for the PicoScope 4444, just removes any offset that is present on both differential inputs. The voltages displayed by PicoScope 6 do not include any common mode voltages, so whether or not the ground clip is connected should...

Hi nurber, It can be tricky to recreate but I found that in a reasonably clean environment (as mentioned by Alan) if you follow the example but use 10Hz instead of 20Hz, and also use a 10s total capture time (1s/div), you should be able to create the waveform. The psdata file is here: Heart-beat tra...

Hi nurber,

As this question is component rather product related, could you email your enquiry in to me at support@picotech.com

Regards,

Gerry

Hi schmidtmotorworks, The way to figure out what you ask is to compare the output specifications of the sensor or amplifier (i.e. the one that will be connected directly to the PicoScope), against the input requirements and specifications of the PicoScope to see if they are compatible. So, here are ...

Hi kuch68, My previous request for your setup diagram, and sanity tests were just to make sure that the regulation was set up correctly (which it is in isolation, with a DC supply). Now, if you look at the internals of the LM317 (page 8 & 10 of the T.I. data sheet here: http://www.ti.com/lit/ds/syml...

Hi mnni, You can set the time reference for logging to Time-of-day, for the Graph View or SpreadSheet View (by clicking the 'tick' icon to select 'options'), and you can save the Spreadsheet file on exit, which will give you a Real-Time reference column in the prn data file that will be the PC inter...

Hi Josh, What is the load on your regulator? As a sanity check could you do the following: [a] Connect the multi-meter to measure current between the PSU and the regulator (i.e. connect the regulator indirectly through the multi-meter instead of directly) then connect the probe tip and ground for ch...

As an update to my last post, you CAN zoom in vertically if you use all of the horizontal axis. This is useful for being able to accurately position a ruler on the converged waveform to verify that it is close enough in value to the automatic measurement of True RMS (as shown in the below screenshot...

Hi Steflibreville, As it is an energy centre I'm assuming that the 3-phase voltages will be classified as CAT II or above, according to the latest IEC 61010-031 standard (or your equivalent national product safety standard, which may have a different prefix in place of the “IEC”). In this case you w...
