6.7.2.7. Number of Records
The number of data records in the GFC 7000TA is limited to about a cumulative one million data points in
all channels (one megabyte of space on the disk-on-chip). However, the actual number of records is also
limited by the total number of parameters and channels and other settings in the DAS configuration.
Every additional data channel, parameter, number of samples setting etc. and will reduce the maximum
amount of data points somewhat. In general, however, the maximum data capacity is divided amongst all
channels (max: 20) and parameters (max: 50 per channel).
The DAS will check the amount of available data space and prevent the user from specifying too many
records at any given point. If, for example, the DAS memory space can accommodate 375 more data
records, the ENTR key will disappear when trying to specify more than that number of records. This
check for memory space may also make an upload of an DAS configuration with APICOM or a Terminal
program fail, if the combined number of records would be exceeded. In this case, it is suggested to either
try from the front panel what the maximum number of records can be or use trial-and-error in designing
the DAS script or calculate the number of records using the DAS or APICOM manuals. To set the
number of records for one channel from the front panel, press SETUP-DAS-EDIT-ENTR and the following
touchscreen button sequence.
