Chapter 4 Features and Functions

Scanning

•Remote Interface Operation: The following command retrieves stored readings from memory (the readings are not erased).

FETCH?

Use the following commands to query the statistics on the readings stored in memory for a specific channel. These commands do not remove the data from memory.

CALC:AVER:MIN? (@305)

Minimum reading on channel

CALC:AVER:MIN:TIME? (@305)

Time minimum was logged

CALC:AVER:MAX? (@305)

Maximum reading on channel

CALC:AVER:MAX:TIME? (@305)

Time maximum was logged

CALC:AVER:AVER? (@305)

Average of all readings on channel

CALC:AVER:COUNT? (@305)

Number of readings taken on channel

CALC:AVER:PTPEAK? (@305)

Peak-to-peak (maximum-minimum)

The following command retrieves the last reading taken on channel 301 during a scan.

DATA:LAST? (@301)

The following command clears the contents of statistics memory for the selected channel.

CALC:AVER:CLEAR (@305)

Use the following command to determine the total number of readings stored in memory (all channels) from the most recent scan.

DATA:POINTS?

The following command reads and clears the specified number of readings from memory. This allows you to continue a scan without losing data stored in memory (if memory becomes full, new readings will overwrite the first readings stored). The specified number of readings are cleared from memory, starting with the oldest reading.

DATA:REMOVE? 12
