Re: 5000 series power supply

Thx Karunen. Do you know how much this was related to sampling rate, etc..?
Thx

Re: 5000 series power supply

Would you have some specs on the current consumption though vs load on the scope ? The digitizer is meant to be included with a system that has other requirements and we can't really guess our way around. It would be better to have a sense of the current draw beforehand.

5000 series power supply

Hi,
I was wondering whether a 5243A (or 5244A) running with 2 input channels at 125MS/s could be powered up with a single USB ? I am hoping that the higher power requirements (1A or more) may only be required for the highest sampling rates and # channels. Thx
Regards,
laurent

Re: Dual Channel input and possible delay

ahem.... I forgot to place two 50 Ohm adapters at the front-end, which seems to solve the issue....

Dual Channel input and possible delay

Some possible issue with a scope acquiring simultaneousl with two channels Set up: Pico 4227 1 input signal, sine wave ~ +/- 2.5V , period ~ 8 microsec Measurement on PicoScope 6: Both Ch A and B on same +/- 5V input range, trigger is on channel A, level 0V. All good The signal feeds into both chann...

Re: 4224 bandwidth

Alright. THx Hitesh.

This would be a reasonable spec to add so it is clear what the instrument is capable of.
Best,

4224 bandwidth

Hi, I am planning to make some measurements with freq centered around 10MHz with the 4224 on the lowest 50mV Range. The specs mentions that the BW drops from 20MHz to 10 MHz with this vertical range setting. Do you have a typical attenuation plot so I can see where there is no attenuation on the sig...

Re: Different readings on ChA&ChaB - 4227

HI Martyn,

Direct connection, no terminators. Swapping cable has no effect. Acquiring A alone, then B alone produces the same results as seen as when acquiring both channels: Channel B shows the same artifact.
Thx.

PS: away from my desk until March 15.

Different readings on ChA&ChaB - 4227

Hi, I am working on an application where I need to acquire a given signal simultaneously on both channels A and B. I use a BNC splitter and BNC cables to connect to the digitizer. To test out the signal I apply a 5 V square wave on the split inputs. I have noticed a discrepancy between the reading o...

Re: Autotrigger in Rapid Block Mode

Hi, Is it still the case that the pico driver does not indicate whether a given capture was acquired from an actual trigger level being detected versus auto-triggering after a set delay (in the absence of the trigger condition)? What happens to a given data capture if I set the auto-trigger delay to...

Re: adc counts

Is there a function call equivalent to ps3000aMaximumValue for 4227 and 4224 ? There does not seem to be a corresponding call to the Max ADC with ps4000.dll

Re: Rapid Block Mode LabVIEW PS4224

Ok, I applied a temp. fix that may be helpful. It builds on the previous example using LV DataReference and correct the "Wrap" by re-shifting each capture by one sample. As a result if one wants to acquire 100 samples, 10times (ncapture = 10), one should set the buffer to 100+10 samples. Then shift ...
