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

Thx Karunen,

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) ? ...

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...

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

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.

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

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

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...

Alright. THx Hitesh.

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

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...

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.

Ok Thx Martyn.

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...

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...
