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.
Parameter
Typical Return
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)
(none)
Read and erase the three oldest readings from reading memory:

The
and
queries can be used during a long series of readings to periodically remove
readings from memory that would normally cause the reading memory to overflow.
does not wait
for all readings to complete. It sends the readings that are complete at the time the instrument
receives the command. Use
or
if you want the instrument to wait until all readings are
complete before sending readings.
l
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-
tionable Data Register's condition register (see
).
