[SENSe<Sensor>:][POWer:][AVG:]FAST

<state>

Enables or disables a fast unchopped Continuous Average measurement. The aver-
age count is enforced to 1. Any setting for average count is silently ignored. See also

"Calculating the measurement time"

Parameters:

<state>

*RST:

OFF

Example:

See

Chapter 10, "Performing Measurement Tasks - Program-

[SENSe<Sensor>:][POWer:][AVG:]SMOothing:STATe

<state>

Enables or disables the smoothing filter, a steep-edge digital lowpass filter. If you can-
not adjust the aperture time exactly to the modulation period, the filter reduces result
fluctuations caused by modulation.

Parameters:

<state>

ON | OFF
*RST:

OFF

Example:

SMO:STAT OFF

Manual operation:
