Frequently Asked Questions
Question: Does any data loss occur if acquisition is turned on and the NET is not
connected?
The damage that occurs depends upon the parameters of the unit. If the unit parameters are set to dump to
disk ONLY then there is no effect, otherwise RAM will fill and acquisition will stop. For further clarification
see the explanation in the section
“Ethernet Port”
.
Question: What happens if the Compact Flash card is pulled from the 130-MC when the
LED is RED.
If the LED shows RED the drive is writing data and should not be removed until the LED changes to GREEN.
Data loss can result from pulling a drive when the LED is RED.
See further explanation in the “Replacing t
he
Compact Flash™”.
Question: Can a different sampling rate be used on different datastreams?
Yes
refer to the table below:
The sample rate list can be broken into two groups:
Group One: The following rates are only available when recording a single sample rate for all streams: 1000,
500, 250 and 125.
Group Two: The following rates may be recorded in any combination within all streams: 200, 100 and 50.
