Reading
Destination
Summary
The reading destination you select will depend on your application.
However, consider the following when selecting a destination:
1. Use
READ? or MEASure? to return readings to the output buffer
when throughput speed is not important or when the number of
measurements is too large to store in mainframe memory.
2. Use
INIT to store readings in mainframe memory when speed is
important. Use
FETCh? to retrieve the readings.
3. Use the
MEMory commands and INIT to store readings in shared
memory (VME memory card) when speed is important and when the
readings will not fit in mainframe memory. Use
FETCh? to retrieve
the readings.
In addition to selecting a destination, you may want to determine
beforehand the number of readings that can be saved in the B-size
mainframe RAM. Consider the following when determining the number of
readings that can be saved:
• Select your System Instrument.
• Send "DIAG:RDIS:CRE? MAX".
• Divide the number returned by four (4)
(this determines the approximate number of readings that can be saved).
You can also determine if a certain number of readings can be stored in the
B-size mainframe RAM by doing the following:
• Select the E1326B multimeter.
• Send "SAMP:COUNt nnn" command
(where nnn is the number of readings).
• Look for an "OUT OF MEMORY" error message
(if the message is NOT generated, then nnn readings can be stored).
