To allocate memory for the capture buffer
1 Set up measurement parameters, as described in the previous task.
2 Press [
Inst Mode
][
TIME CAPTURE
][
BUFFER LENGTH
], then enter the amount of time
data you want to capture (in seconds, blocks, or points).
3 Press [
ALLOCATE BUFFER
][
CONFIRM ALLOCATE
].
The size of the time-capture buffer is affected by the value of [
BUFFER LENGTH
]and
several measurement setup parameters. If the buffer required for the current setup is
too big to fit in the available memory, the analyzer automatically reduces the value of
[
BUFFER LENGTH
] until the buffer just fits. A message is displayed to let you know
that the buffer length has been reduced. If you see this message, press [
System Utility
]
[
MEMORY USAGE
] to see if you can free additional memory for the buffer.
If you forget to press [
ALLOCATE BUFFER
] before you begin filling the time-capture
buffer, the analyzer automatically performs an equivalent operation when you press
[
FILL BUFFER
]. However, it is generally better to use [
ALLOCATE BUFFER
]: This will
minimize the delay between pressing [
FILL BUFFER
] and the beginning of data
collection.
