Trigger Delay potential issue with 5244A

Hello, Setup: SDK 13.6.10.22 (32 bits). on Win7 PC Pico 5244A scope Using Labview examples. Scope setup: Channel A : 10V range Sampling: 250MS/s # samples: ~ 2000 # pre-triggered: ~ 200 Rapid Bulk Acquisition as per examples. # triggers to acquire: 100 Auto_trigger_ms = 10ms Description: I am sendin...

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...

Re: 5000 series power supply

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

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....
