DATA:REMove? <num_readings> [,WAIT]
Reads and erases <num_readings> measurements from the reading memory. If fewer than <num_read-
ings> measurements are available, the query returns an error unless the WAIT parameter is specified, in
which case the query waits until <num_readings measurements are available.
34460A: 1 to 1,000 readings
34461A: 1 to 10,000 readings
34465A/70A: 1 to 50,000 readings (without the MEM option), or 1 to 2,000,000
readings (with the MEM option)

You can store up to 1,000 measurements in the reading memory of the 34460A, 10,000 meas-

urements on the 34461A, 50,000 measurements on the 34465A/70A (without the MEM option), or
2,000,000 measurements on the 34465A/70A (with the MEM option). If reading memory overflows,
new measurements overwrite the oldest measurements stored; the most recent measurements are
always preserved. No error is generated, but the Reading Mem Ovfl bit (bit 14) is set in the Ques-
