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...

Re: Running a 6000 series scope off batteries

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 ...

Re: for my 3425

Hi Pico3425, To answer your question about the ground socket on the PicoScope, and following on from your previous question: You can use the differential probes that come with the scope to measure the potential difference between 2 points in a circuit, or system even if neither of them are at ground...

Re: for my 3425

Hi liu, Regarding how to connect and measure differential signals, page 10 of the user guide here: https://www.picotech.com/download/manuals/ps3425-en-3.pdf gives details on how to do this. Regarding the considerations of using a differential scope, and whether you need to use a laptop that is conne...

Re: looking for the right equipment

Hi, As discussed, all of our PicoScopes and PicoLoggers require a USB connection to a powered device in order to operate and transfer acquired data for storage. So, to perform unattended logging sessions, you would need to use one of our supported small form factor, portable platforms, such as Raspb...

Re: Integrator issue

Hi Mich, To answer your question, you are getting a result - but not one that you can see. Because the finite integral of the waveform w.r.t. the total collection time is a product of the total collection time (you should notice that the vertical axis of the integral waveform has units of Volt Secon...

Re: Thermocouple Data Logger TC-08 - Input Channel Isolation

Hi Lightsphere,

The TC-08 channels are not isolated from each other they have weak pull down resistors, and capacitors that are tied to ground.

Best regards,

Re: Effective number of bits of 5244B

Hi Herve, Sorry for the delayed response. To answer your original question, your calculation sets an upper limit for ENOB but doesn’t give the full picture of dynamic performance. When ADC’s are interleaved in time to create a faster sample rate, there is an inevitable bit of distortion of phase, ga...

Re: Phase locking with PicoScope 5000 series

You are correct in that the signal Generator (of which the AWG is a part) and the ADC and acquisition circuitry are driven by the same clock. Also, the waveform of the signal generator will always be in sync, and therefore the same number of cycles will be captured, for any fixed time period. If thi...

Re: Using Differenti​al Probe TA043 with Rigol 1204B Scope

Hi Zhiyong, The current sensing transformer although it may have quite a high frequency response is unlikely to be able to react to almost instantaneous changing current (it can't accurately reproduce a pulse as the core limits the frequency response to less than 8 harmonics). What you're measuring ...

Re: PicoScope oscilloscope software on BeagleBoard / BeagleB

Hi Mike,

Apologies for the delay. We have a number of options that we need to consider, and are currently establishing the support process and access to the drivers for this exciting development. We will give you an update in due course.

Best regards,
