Re: Intel Skylake bug and Picoscope software

Hi derryuk, Unfortunately, as this is a 3rd party hardware/firmware issue, and we have limited information at this point in time, there is no way to be 100% certain. However, this may be easily fixed as there appears to be a BIOS fix that is being distributed for it. Just for reference though, the r...

Re: Performance of Picoscope 4262 does not reach expectation

Hi Audioguy, We are not aware of any known aliasing issues with the PicoScope 4262, and we can get clean results (without any significant aliasing) right up to 5MHz signals. The transfer of data (or lack of) between the different views depending upon whether they are split, switched, and which one i...

Re: Bug report - file deletion on save.

Hi Zane,

Do you mean that the exported file is being deleted, a previously saved psdata file is being deleted or that the psdata file is just not being saved?

Regards,

Gerry

Re: Measurements

Hi BDR, How are you calculating the RMS values? If you're calculating the values from the raw sample data, but only displaying RMS values every 2 or 3 seconds, then you would be better off letting the driver reduce the amount of calculations that need to be done, by downsampling in 'Average' mode, a...

Re: picoscope 2204A => data logger

Hi will87, Following on from my previous comment, if you wanted to log data in PicoScope, it can be done by automatically saving a file once the data has been captured (using alarms). This process can continue for as long as you need to log the data, however, if you are capturing a lot of data, you ...

Re: RS422 interface

Hi uarter20, Could you explain exactly how you would be delimiting the bytes of your data. Also, are you using some other method of synchronization, such as pins (otherwise how would you be able to prevent the timing between Tx and Rx from drifting out of sync during a long transmission). Our curren...

Re: picoscope 2204A => data logger

Hi will87, You won't find data logging functions in our PicoScope 6 software. Our PicoLog data logging software is what you need to use for saving data to a file over long periods of time. PicoLog allows you to save data to a file and view it at the same time in graph mode or tabular (spreadsheet mo...

Re: Measurements

Hi BDR, Transfer rates over USB can vary widely due to the real time utilization of the bus, and we have found that the fastest reliable transfer rate of PicoScope data over USB 3.00 is 156MS/s. For this reason the maximum streaming rate has been capped at that rate. The exact sample interval used s...

Re: FFT SW improvements

Hi Springburo, A standard spectrum analyzer, that uses a sweeping bandpass filter as the 'window' for detecting signals, enables the bandwidth of the filter to be changed via the front panel of the analyzer. It's bandwidth is also known as the 'Resolution Bandwidth' (RBW) of the analyzer, and althou...

Re: Guide to measure conductivity

Hi John, Purely for reference, a good way to measure small changes in resistance would be to use a wheatstone bridge. However, Pico Technology strongly advises against the use of any of our products where the application involves direct contact with the body. There are strict standards applicable to...

Re: 6402D persistence mode issue

Hi Michel, The mechanism used on the PicoScope 5000 series for external triggering differs subtly from the mechanism used on the PicoScope 6000C/D series. Replicating the signals that you used in your tests, the 6403D has a lower trigger limit below which the triggers reduce or stop. For the units w...

Hi nickgb, I was waiting to see if anyone would reply, because at Pico we're not in the business of randomly endorsing a product, but as they haven't, I can share my experience with you as a consumer, and in no way connected with Pico Technology. The orignal 6404 PicoScopes consume approx 2A with al...

Re: Driving a Solid State Relay with PicoLog 1216

Hi KEggemeyer, The PicoLog 1216 output, can directly drive the base of a suitable transistor (or gate of a suitable FET) such that the collector (or Drain) can "Pull Down" the coil of a relay (the other end of the coil being taken to, say, +5v. To be safe, add a small diode across the relay coil to ...
