Select a partition type for your file.
Select the maximum number of records you want to be recorded in the file.
The number of records in the waveform log file needed to store one waveform event
(series) is defined as follows:
Number of Records per Series = Sampling Rate (Samples per Cycle) x Number of Cycles
per Event / 512
The total number of records you must allocate to store the required number of events
(series) is defined as follows:
Number of Records = Number of Records per Series x Number of Series
For example, if you want to record a 64-cycle waveform sampled at a rate of 32 samples
per cycle, the number of records required for one waveform series would be:
Number of Records per Series = (32 x 64)/512 = 4.
If you want to allocate space sufficient to store 20 waveform events (series), you should set
up the waveform log file for 4 x 20 = 80 records.
Click OK, and send your setup to the meter or save to the database.
Click “Setup Recorder”, or click on the “Waveform Recorder” tab.
The following table lists available waveform options.
Option Format/Range Description
Samples per Cycle 32, 64, 128 Waveform sampling rate
Cycles per Series 16-2560 (32 samples/cycle),
8-1280 (64 samples/cycle),
4-640 (128 samples/cycle)
Defines the total duration of the
waveform per event/series
Before Cycles 1-20 Defines the number of cycles to be
recorded prior to event
Num. of Channels 1-6 The number of the simultaneously
recorded channels
