Features and Functions
Storing and clearing readings
You can store up to 1,000 measurements in the reading memory of the 34460A, 10,000 measurements on
the 34461A, 50,000 measurements on the 34465A/70A (without the MEM option), or 2,000,000 meas-
urements on the 34465A/70A (with the MEM option). Readings are stored in a first-in, first-out (FIFO) buf-
fer; when reading memory is full, the oldest readings are lost as newer readings are taken.
In Local (front panel) mode, the instrument collects readings, statistics, trend chart and histogram inform-
ation in the background, so if you select any of those options, the data is ready for viewing. In Remote
(SCPI) mode, the instrument does not collect this information by default.
Changing the instrument from Local to Remote does NOT clear any readings in memory. Changing the
instrument from Remote to Local DOEs clear any readings in memory.
In general, you turn the reading of measurements on and off by pressing [Run/Stop], as described above.
You can also take one reading or a specified number of readings by pressing [Single].
To save readings, press [Acquire] > Save Readings. Then use the menu that appears to configure the loc-
ation where you want to save the readings:

l
represents approximately 252 M readings with Metadata Off, or 159 M readings with Metadata On.
For 1M, the limit is 1,000,000 rows in the resulting file. This allows you to accommodate common
l
spreadsheet, database and data analysis programs that have limitations of 1 million rows per file.
Metadata - Enables reading number, time stamp of first reading, and sample interval (if available) in the
file.
Separator - Specifies the character (Comma, Tab, or Semicolon) to use for separating the information on
each row.
When finished configuring reading storage, press Done > Save Readings to save the readings in memory
