CSAT3 pipeline delay 8.1 Sampling Modes The CSAT3 can be configured to make measurements in either a singlemeasurement mode or an oversampled mode. In the single-measurement mode, the CSAT3 makes one measurement synchronously with the trigger provided by the CSAT3 internal trigger, SDM communications, or RS-232 communications. In the oversampled mode, the CSAT3s internal trigger, SDM communications, or RS-232 communication trigger several measurements. The average of these measurements is output at the trigger rate. 17

Sampling Modes
The CSAT3 can be configured to make measurements in either a single-
measurement mode or an oversampled mode.
In the single-measurement
mode, the CSAT3 makes one measurement synchronously with the trigger
provided by the CSAT3 internal trigger, SDM communications, or RS-232
communications.
In the oversampled mode, the CSAT3s internal trigger, SDM
communications, or RS-232 communication trigger several measurements.
The average of these measurements is output at the trigger rate.
