Metering Keys - Agilent Technologies 66311A User Manual

Metering Keys

Metering keys control the metering functions of the dc source. As set from the factory, all front panel
measurements are calculated from a total of 2048 readings taken at a 46.8 microsecond sampling rate.
Therefore, the factory default acquisition time for a single front panel measurement is about 100
milliseconds. Refer to "Making Front Panel Measurements" for more information about changing the
front panel sampling rate and the number of measurement points.
NOTE: The front panel sample rate and data point settings are separate and independent of the
sample rate and data point settings that are programmed over the HP-IB interface. When
an HP-IB measurement is in progress, the front panel display temporarily indicates
-- -- -- -- --. Front panel measurements resume when the HP-IB measurement completes.
HP-IB measurements are discussed in chapter 7.
