About Analog Outputs of Analog Discovery 2

[Paul Chang]

Dear sir,

I would like to know Analog Outputs limitation.

Does it can support the requirement ?

AC Freq range 0.05 Hz～120Hz
AC voltage range: -10mV ~ +10mV
AC resolution : <0.1mV
DC offset  is greater than -1000mV ~ +1000mV: 
DC offset resolution 5mV

special AC
AC overload test : 1 Vpp @50Hz/60Hz

Another question:

Can it measure input loop current <0.1uA?

 

Best Regards

Paul

Hi @Paul Chang

See my comment in bold:

AC Freq range 0.05 Hz～120Hz Yes: uHz ~ MHz
AC voltage range: -10mV ~ +10mV Yes
AC resolution : <0.1mV Almost: ~0.18mV
DC offset  is greater than -1000mV ~ +1000mV: Yes: -5V ~ +5V
DC offset resolution 5mV Yes: ~0.67mV

special AC
AC overload test : 1 Vpp @50Hz/60Hz
I don't know what does this mean.

Another question:
Can it measure input loop current <0.1uA?
There is no current measurement in the device but you could use the differential scope inputs (3mV/0.3mV resolution) with shunt resistor.
