Re: 5244D - no response from LabVIEW

--> using ps5000aOpenUnit call instead of the "-2" version fixes it. Make sure the call change is actually taken in the CN node, I had tried that test yesterday with no luck... :shock:

What about all these "ver 2" calls though?

Re: 5244A and 5244D

Thx Martyn.
Are their SDK function calls I should look at more specifically, ones that may break using the D, or expected modifications at the application level, with the updated SDK please? Thx

5244A and 5244D

Hello, I have a few questions about the versions A and D of the 5244 picoscope: - Beside migrating to USB 3.0 with the D version, are there any other changes documented beside the one I found in the API programming guide for 5000A rev 4? - Which 5000 series sdk version work with the 5244D (would Pic...

Re: ChA&B Block mode trig behavior with 4227

Hi Hitesh,
Which SDK would have this correction please?
I see the one avail is older than the last conversation we had about this in Feb.
Thx

ChA&B Block mode trig behavior with 4227

Hi I am experiencing some bizarre behavior with a 4227 that I would like to share and see if you can reproduce on your bench: HW : 4227 ; SDK r_10_5_11; IDE : Labview 2011, using the ExampleRapidBlock as the base program for testing. Signal: I feed the same 500Hz square pulse (0-5V) on both ChA and ...

Re: Noise Floor - 5000 series - 4227

Hi Hitesh. Thanks for the further info. Yes I understand 4227 and 5000 series are different, nevertheless the performance does not seem drastically improved. Noise floor is really important to pick up small signals, independently of the bit resolutions. The specs on the 5000 state a RMS noise as cop...

Re: Noise Floor - 5000 series - 4227

Thx Hitesh,

So what would be the DC RMS for the 5000 please?

So does this mean a 12-bit 4227 has:
- similar noise level than a 5000 in 15-bit mode (!)?
- better noise level than a 5000 in 8, 12, 14 -bit modes?

Thx

Noise Floor - 5000 series - 4227

Hi As per the 5000 series specs , noise figures are presented as : Noise (on 50 mV range) : 8-bit mode 120 μV RMS 12-bit mode 110 μV RMS 14-bit mode 100 μV RMS 15-bit mode 85 μV RMS 16-bit mode 70 μV RMS Does this noise represent the AC RMS noise or True RMS noise (--> including the DC component) ? ...

Re: 5000 series power supply

Thanks Karunen. The settings would be as follows: • 5243b, sampling Rate: 125 MS/s, 15 bits res. • 2 inputs: one on ~ 2V range, one on 50mV Range, • voltage source (if enough current available) : USB: 5V (PC) • Waiting for triggers coming in at 512 Hz. # samples on each channel to acquire for each r...
