DATA:POINts?

Syntax

DATA:POINts?

Description

This command returns the total number of readings currently stored in reading memory from a scan or internal DMM measurements.

Used With:

  • 34921A through 34925A Multiplexer Modules

  • 34950A Digital I/O Module (digital input and counter channels only)

  • 34952A Multifunction Module (digital input and totalizer channels only)

Remarks

  • You can read the count at any time, even during a scan or a series of internal DMM measurements.

  • You can store at least 500,000 readings in memory and all readings are automatically time stamped. If memory overflows, a status register bit is set and new readings will overwrite the first (oldest) readings stored. The most recent readings are always preserved. Reading memory is not cleared when you read it.

  • The instrument clears all readings from memory when a new scan is initiated, when any measurement parameters are changed (CONFigure and SENSe commands), and when the triggering configuration is changed (TRIGger commands).  

  • The instrument clears all readings from memory after a Factory Reset (*RST command), after an Instrument Preset (SYSTem:PRESet command), or when mainframe power is cycled.

Return Format

The command returns a value between 0 and approximately 500,000 readings indicating the number of readings currently stored in reading memory.

The following query returns the number of readings in memory.
