Internal Format

This command selects the internal data format of the measurement result from the SENSe block. The purpose of the command is to increase the measurement speed.

Parameters:

REAL means that the result is calculated in real-time after each measurement.

PACKed means that the raw measurement data is stored internally and the result is not calcu- lated in real-time between measurements. The results are calculated later when they are sent to the controller. Since the result is not calculated, other blocks cannot use this data. That means that you cannot have the DISPlay, OUTPut, and CALCulate blocks switched on when using PACKed format.

The following measuring functions in PM6680B/81 cannot be used with PACKed format: Phase, Duty Cycle and Volt.

PM6685 cannot used PACKed format with Duty Cycle.

The internal format affects the number measuring results that the measurement re- sult buffer can hold.

		Number of Results in
		Buffer
Format	Measuring Function	PM6680B/85	PM6681
Real:	All functions	2048	7019
Packed:	Frequency, Period, Ratio Totalize	2166	6143
	Pulse Width, Time-Interval, Rise/Fall time	764	4466
	Phase, Duty Cycle, Volt	N.A.	N.A.
	Low resolution Frequency and Period	N.A.	8191
	Low Res. Time-Interval and Pulse Width	N.A.	4095

You must consider this when fetching results with the :FETCh:ARRay query.
