From the front panel, the instrument prevents you from specifying a sample timer that is
shorter than the time required to make measurements based on the present function, range,
and integration time.
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

For the 34460A/61A only, press
Save Readings
to save the readings in memory to a file.
For the 34465A/70A only, press
Options
to configure reading storage options:
Rows/File
- Specifies the maximum number of rows or readings to be written to a file.
l
For
Max
, the limit is the number of bytes allowed by the file system (2
32
= 4.294967296 GBytes). This
represents approximately 252 M readings with Metadata Off, or 159 M readings with Metadata On.
l
For
1M
, the limit is 1,000,000 rows in the resulting file. This allows you to accommodate common
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
