3 Operating the DC Power Analyzer
66 Model N6705A User’s Guide
The Duration fields let you specify the duration of the data log in
hours, minutes, and seconds. The maximum duration is 99,999 hours.
The Sample period specifies the interval between data samples in
milliseconds, which can be set from 1 millisecond to 60 seconds.
Check Log Min/Max to log the minimum and maximum values to the
data log file when in Continuously-sampled mode. When Log
Min/Max is checked, it will triple the resulting file size.
The Resulting file size text box indicates the file size when the data
log completes. The maximum file size is 2E9 bytes (1.87 Gbytes in
Microsoft Windows units). If settings exceed this limit, the logging
interval will automatically increase to keep the size within the limit.
If the file size exceeds the available space on the drive to which it will
be written, an error is generated and the Data Logger will not run.
Trigger
Select the Trigger button to configure the trigger properties. The
Data Logger uses triggers to synchronize itself with an external event.
The Source dropdown list lets you select a trigger source. The same
trigger source will be used to trigger all of the outputs that have been
configured for data logging. Depending upon the selected trigger
source, you can trigger the Data Logger as follows:
Trigger Source: Description:
Voltage <1-4> level
Current <1-4> level
Triggers the Data Logger when the voltage or current of the
corresponding output passes through the specified level.
Run/Stop key
Trigger the Data Logger when the Run/Stop key is pressed. This is the
default trigger source.
Arb Run/Stop key Trigger the Data Logger when the Arb Run/Stop key is pressed.
Output On/Off key
Trigger the Data Logger when any of the Output On/Off keys are
pressed. Also applies to the All Outputs On/Off key.
BNC Trigger input
Provide a low-true signal to the BNC trigger input connector. The
signal must have a minimum pulse width of 2 microseconds.
Remote Command Send a trigger command over one of the three interfaces (i.e. *TRG).
