number of sensors connected and their measurement modes. With one sensor connec-
ted, operated in the ContAv mode, it is about 1 ms.
Switching on the averaging filter does not affect the refresh rate, but the speed at which
the output voltage changes can be expected to slow down as a result of the filter effect.
For applications having high requirements on the dynamic behavior of the analog outputs,
for example leveling loops, it is advisable to freeze the screen of the R&S
NRP2 to avoid
interruptions caused by writing to the display memory (
