7.1 Types of Files
• ######## represents a file name set by a user.
• The same file cannot be stored in both the PC card and the inter-
nal memory.
• When the medium for saving data is set to PC card, if the PC
card is not installed or the 3169-20/21 fails to write data to the
PC card, the data will be stored in the internal memory as a
backup data file (automatic output data only).
• The PC card and internal memory each hold up to 100 files:
measurement data files, waveform data files, backup data files,
and screen copy files.
The PC card holds up to 10 setting files. The internal memory
holds up to 5 setting files.
• When reading a file in binary format into commercially available
spreadsheet software, convert the file into a text file. The CD-R
supplied with the 3169-20/21 contains the conversion software.

For the headers of measurement data, see the list in the "Appendix"
(page 197)

Status Data (STATUS)
Status data is added to measurement data files (standard interval).
Status data consists of a 10-bit binary number, as shown below. It
indicates the occurrence of over-range, excessive input (excessive
crest factor), power outage, or other situations that may occur dur-
ing time-series measurement.
ov: Excessive input: The file contains data with an excessive crest
factor.
or: Over-range: The file contains data exceeding 130% of the
range.
pd: A power outage has occurred.
PLL: PLL unlock: PLL unlock has occurred.
For example, if a power outage occurred during time-series mea-
surement, the status data will be shown as "0100000000."

The zero of the upper bit may not be indicated on commercially
available spreadsheet software.
