measurements. Sending READ? is similar to sending

l
The
query does not erase measurements from the reading memory. You can send the query
multiple times to retrieve the same data.
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
).
l
The instrument clears all measurements from reading memory when the measurement configuration
changes, or when any of these commands are executed:
