RE: adc2mV and Python's picosdk

Post by JamCam »

Hi there,
In the ps4000blockexample of the picosdk module for Python, the maximum ADC count value is given as:

Code: Select all

maxADC = ctypes.c_int16(32767)
However, the PicoScope 4262 has a 16-bit ADC, so, should this not be 65536?

In the case that both channels are enabled, is the effective ADC count value reduced to (2^n - 1) per channel, where n is the resolution of the ADC (16-bits)?

Many thanks

Signed 16 bit as the voltages can be positive or negative.
