READ?
Starts a new set of measurements, waits for all measurements to complete, and transfers all available measurements.
Sending READ? is similar to sending INITiate followed immediately by FETCh?.
Parameter Typical Return
(none) -4.98748741E-01,-4.35163427E-01,-4.33118686E-01,-3.48109378E-01
Transfer measurements from reading memory:
READ?
l The FETch? 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 or 10,000 measurements on the
34461A. If reading memory overflows, new measurements will 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 Questionable Data Register's condition register (see Status System Introduction).
l The instrument clears all measurements from reading memory when the measurement configuration changes, or
when any of these commands is executed:
